POWER FOR THE MTEK6000
MOUNTING THE INSTRUMENT ON
THE METER
Two 4.5V alkaline battery packs (part #
1011-0035C-001) supply operating power to
the device for approximately two years of
typical operation. Recommended operating
temperature range for the MTEK6000 when
powered with these packs is –4 F (-20 C) to
130 F (54 C). If this supply should fail, an
on-board back-up battery will maintain the
unit's memory and real time clock. Backup
power can maintain history data for up to
seven years. When back-up power is used,
the unit discontinues normal operation until
the main battery pack is replaced.
1. Check the meter's rotation direction.
Standard setup is clockwise rotation of the
meter output shaft, as viewed from the top.
The rotation of the unit can be changed to
counterclockwise. Also, the input drive
value for the unit can be changed.
2. Align the instrument's index base plate
holes with the corresponding holes in the
meter's index base plate. Secure the unit
by bolting it to the meter. Ensure that the
drive dogs are correctly aligned and not
binding.
Note that only one power source powers
the MTEK6000; connection of battery
packs to a unit configured for external
power does not provide an additional
source of backup power for the unit.
3. Plug all unused holes in the index base
plate with the caps provided in the
accessory package.
Optional Power Supplies
Several optional supplies are available:
A. Two Single-D Lithium battery packs -
(part # 1011-0039B-001) provides an
approximate life expectancy of two years
over the temperature range -220 F (-300 C)
0
to 1580 F (70 C). Each 3.6V, 13.0 AH
battery pack can be used individually (~
1yr life) or as a pair.

When changing a MTEK6000 in the field
from a 10, 100, 1,000 or 10,000 ft3/rev drive
meter with a 5 ft3/rev drive, the CF per Pulse
In or Meter Drive parameter, must be
changed to a value of 10 using software or the
optional, external keypad / display.
7. Take care to align the gears properly, and
verify that they turn freely and do not
bind.
NOTE
Electronic parameter CF per Pulse In or
Meter Drive should always equal the meter
drive value EXCEPT for 5 ft3/rev meters
which should be set at 10. When switching to
5 ft3/rev, the gear ratio is adjusted so that two
revolutions of the input drive gear result in
one revolution of the magnet and hub
assembly, which sends a pulse signal to the
instrument that equals 10 ft3/rev. The value
can be changed using software or the
optional, external keypad / display (see
Appendix A for addressing).
To change the input drive value to 10, 100,
1,000 or 10,000 ft3/rev, return compound gear

PULSE INPUT TO THE MTEK6000
Software is used to configure the pulse input.
The optional, external keypad / display can
also be used to configure the pulse input and
other parameters. See Appendix A for
addressing.
Magnetically operated reed switches inside
the meter drive assembly send electronic
pulses as the drive turns. These pulses
represent uncorrected meter volume to the
instrument.
WALL AND PIPE MOUNTING
To eliminate false counts that can result from
the reed switch "bounce”, the MTEK6000
The MTEK6000 can also mount directly on a
wall or on a pipe. Mounting feet are provided
for wall mounting. See Figure 2-5.
uses
a
set/reset,
dual-reed
switch
configuration. An input pulse is generated
only when the opening and closing of the
first switch is followed by the opening and
closing of the second switch. The main
counter input is also monitored for fault
conditions. When enabled, if any of the dual-
reed switches should be defective, the input
pulses will automatically switch to the
working counter input and the MTEK6000
will generate a Faulty Counter alarm. This
function is enabled if the Counter Fault
Monitoring parameter is set to 1 and
disabled if set to 0. The default value is 0 for
disable. See Appendix A for addressing.
For pipe mounting, approximately 10 feet of
2-inch rigid iron pipe or conduit is required.
The pipe should be installed 18 to 24 inches in
the ground in 6 inches wide concrete. The
length of the 2-inch mounting pipe or conduit
will vary according to the site, but typical
installations place the MTEK6000 at about
eye level for ease of operation. Mounting
plates are provided for pipe mounting. Secure
the MTEK6000 to the pipe with the provided
U-bolts, washers and hex nuts. See
Figure 2-6.
For units supplied with indexes, the main
counter input is terminated at the UNIT
(BLK) MTA connector and the uncorrected
pulse wiring at the FIELD (WHT) MTA
connector at the lower right hand corner of
the corrector printed circuit assembly.
Metretek, Inc. can supply a remote index
similar to the main index or a sandwich
pulser for wall or pipe mount installations.
When the sandwich or external pulser option
(1, 10, 20, or 50 pulse per revolution) is
supplied, connect the N.O., COM, and N.C.
wiring to terminals 32 (SET1), 33 (GND) and
34 (RST1) respectively.
The pulse input is software selectable for
Form C (three-wire) or Form A (two-wire)
connection.

prevent possible damage. The probe is
designed to fit into standard Metretek, Inc.
thermowells. Optional 15-foot (4.5 meter)
and 30-foot (9-meter) cables are available.
See Fig 2-10.
To install the thermal probe, use the supplied
temperature probe adapter. Refer to Table
2-1. Insert the probe into the thermowell and
tighten the securing nut FINGER TIGHT

Users retrofitting instruments requiring the
5/8” adapter can order the adapter from
Metretek, Inc.
Oil or ethylene glycol (antifreeze) should be
used to improve heat transfer from the
thermowell to the thermal probe. Be aware,
however, that it is possible to cause hydraulic
crushing of the probe. This can happen when
there is little or no air in the thermowell
above the probe. When the probe is fastened
by tightening the securing nut, the space in
the well decreases as the probe enters. As a
result, hydraulic pressure may rise high
enough to cause damage. If you use oil or
antifreeze, make sure there is enough air
in the thermowell above the fluid to
prevent crushing the probe.

INSTALLING THE PULSE OUTPUT
WIRING
configuration requires that a constant wetting
current be available at both the normally open
and normally closed terminals by the device
attached to that pulse output.
The MTEK6000 comes standard with a
board installed that provides two optically
isolated pulse outputs. These outputs are
configurable as either Form C or Form A
type outputs. An alternative version of the
board is available that provides four pulse
outputs. Both versions of the board also
provide terminal block positions to access the
uncorrected mechanical volume switch
output of the index. See Fig. 2-11 for pulse
output wiring. The option boards optical
coupling and physical arrangement of
circuitry provide a minimum of 1,500 volts
of isolation.
The corrected volume pulse output generated
can be scaled to any desired volume value.
Typical values are 10, 100, 1,000, or 10,000
cubic feet per pulse, or the metric equivalents.
The scaling factor is selected by the Pulse
Out CF Per Pulse parameters. The pulse
duration (width) is also configurable up to
5,000 ms. The Pulse Output On-Time and
Off-Time parameters determine the pulse
time for corrected volume, uncorrected
volume and pressure corrected volume pulses.
The Alarm Pulse Time (ms) parameter
determines the pulse time for alarm outputs.
See Appendix C in this manual or Meter
Reader Help screen for description of this
parameter.
Wiring connections for the pulse outputs are
made from terminals 19 to 17 for Pulse
output #1, terminals 16 to 14 for Pulse output
#2, terminals 13 to 11 for Pulse output #3 and
terminals 10 to 8 for Pulse output #4. See
Fig. 2-11 for pulse output wiring location and

Volume and Alarm Pulse Specifications
Uncorrected Pulse Output Specifications
1. All pulse outputs are isolated from
ground and each other. Provides 1,500
volts between input and output and
between contact sets.
1. 3W contact rating (power dissipation).
2. Maximum switching voltage up to 30V.
3. Maximum switching current up to 200mA.
4. Maximum continuous current @ 500 mA.
2. Form C: DC load only, 125mWdc max,
50Vdc max
Form A: AC or DC load 800mW max,
400V max., 100mA max, continuous
3. Configurable pulse width from 1 to 5,000
milliseconds (ms).
NOTE
All pulse outputs are disabled in the standard
unit to conserve power. The Alarm pulse
output is a one time pulse output signal. No
other alarm pulse will be generated until the
alarm is cleared and becomes active again.
Uncorrected Mechanical Pulse Output
(Units with a Metretek Index)
The uncorrected mechanical pulse output is
derived from the Form C reed switch in the
index assembly. As the magnet in the drive's
assembly rotates past the Form C switch, a
single uncorrected volume pulse output is
generated. Volume per pulse is determined
by the drive rate. Each uncorrected volume
pulse is equal to the gas flow for one shaft
revolution.
The pulse output can be wired as a Form A or
Form C switch output. Use terminals 25
(normally open), 24 (common) and 23
(normally closed) for Form C output. To
wire as Form A, use terminals 25 (normally
open) and 24 (common) and make no
connection to terminal 23 (normally closed).
The duration (width) of each pulse is equal to
the length of time the reed switch is in its
closed position (depends on the rate of the
meter). No configuration is necessary to
enable the uncorrected mechanical pulse
output.

GROUNDING
case it is of no benefit to earth ground the
MTEK6000’s external lug.
The information presented here is merely a
guideline to help customers avoid surge damage
to the MTEK6000. None of these guidelines are
to be construed as replacing or superseding
rules and practices defined by the National
Electrical Code (NEC), or the Classification of
Gas Utility Areas for Electrical Installations
guidelines, as published by the American Gas
Association (AGA) or other regulatory agency.
A sound understanding of Federal, State and
Local laws is fundamental to proper and legal
installation work.
When the external ground lug of the
MTEK6000 is to be used, it should be
connected to a common ground rod (or "bed"
of grounding equipment) to which is securely
tied all other equipment chassis, metal
cabinets, and intrinsic ground brackets. Solid
copper ground wire or ground strapping of an
approved size and type must be used to tie this
equipment to the rod. If possible, it is far
preferable that all external equipment be tied
to a single site ground, that the distance
between the MTEK6000 and external
equipment is kept at a minimum (less than 20
feet is best), and the ground rod be located no
farther than halfway between the MTEK6000
and the other equipment.
The MTEK6000 is configured so that the
majority of the internal metal components
within the device are connected (common) to
the gas pipeline / meter to which the
instrument is attached. Additionally, a large
surge bypass MOV device has been provided
inside the MTEK6000 that provides an
alternate path (rather than through the
correctors electronics!) for surge current to
flow. One side of this device connects to the
pipe through the index & meter. The other
side is brought out through the enclosure to
an external copper grounding lug. The
separation of these two points allows for the
existence of cathodic protection voltage
levels on the pipe (typically about 1 volt
below the surrounding soil) while still
providing a path for surge current to safely
bridge these points, find earth ground, and
not damage the instrument.
If separate site grounds must be used, as when
the MTEK6000 and UPS are separated by a
distance greater than 20 feet, Metretek can
provide an optional device, the SPM (Surge
Protection Module). A pair of SPMs can
properly protect both devices in this
circumstance. Control drawings detailing
proper wiring of SPMs (including hazardous
areas) are included with the SPM.

the unit operates in a protective mode. The
on-board battery will continue to protect the
unit's memory; therefore data prior to
entering this mode will be maintained. The
supply voltage is monitored constantly and
the unit will reset itself should the supply
voltage become greater than 6.0 volts. If the
unit is left alone without applying adequate
supply voltage, the battery will continue to
drain and the outside display will eventually
go blank.
Lost Differential Pressure Alarm (EFM)
A Lost Differential Pressure alarm is
generated when the differential pressure
circuitry is over-ranged. This can occur if
the differential pressure transmitter is

temperature, and the rest of the analog
channels are sampled, and the unit executes
the processes and run calculations.
2. Display the desired parameter. Press
jump followed by the address of the
parameter, and then press ent (see
Appendix A for parameter addressing
for your device).
3. Assign a function key to the parameter.
Press jump, edit, and then the function
key you wish to assign to the current
item [F0 - F9].
In this mode, the EFC should be configured
to wake-up on the number of specified
pulses along with an hourly wake-up to

CHAPTER 4: OPTIONAL EQUIPMENT
ANALOG OUTPUT (AO) OPTION
The Analog Output Module (part # 1021-
0001B-001) and connecting cable (part #
1002-0245B-001) provides a two-wire,
loop-powered, optically isolated, precision
4-20mA output. This module interfaces
with the MTEK6000 series product line to
provide a 4-20mA output for flow rate,
pressure, or numerous other control and
monitoring applications. Up to two modules
can be installed in the MTEK6000 in place
of the batteries by using the AO module
adapter plate, (Metretek stk #1008-0011B-
001).
Power for the digital interface section of the
AO is selectable by using the DIPswitches,
and can be supplied by Vcc of the
MTEK6000 or from the main supply
voltage. The AO module interfaces to an
MTEK6000 series product via the standard
I2C serial interface bus. The MTEK6000
unit requests the desired mA output from the
AO module using this bus. An I2C digital
I/O chip is used to send the information to
the analog output section of the AO board.
The analog output section of the board
derives its power from the current loop, and
is optically isolated from the digital control
interface section. The analog output section
receives commands from the digital I/O chip
through opto-isolators. Commands are in
the form of a serial data stream. The AO
module provides 4-20mA output signals
with a resolution of 1 part in 65536 (16 bit).
The D/A also allows for over-ranging of the
output to a minimum of 3.5mA and a
maximum of 24mA. The field interface to
the D/A is a simple two-wire connection.
Reverse polarity protection is provided.

AGA-8 Supercompressibility Gross Method 1
APPENDIX B: CALCULATIONS
The EFC is configured with values for BTU
content, specific gravity and mol percent of
CO2.
AGA-7 Volume Calculations
The MTEK6000 EFC performs volume
calculations based on the Ideal Gas Law.
Boyle’s Law is used for pressure and
Charles’s Law for temperature. These laws
state that the volume of any definite weight of
a perfect gas varies inversely with change in
absolute pressure and directly with change in
absolute temperature. The unit can perform
such calculations for turbine, rotary, and
diaphragm displacement meters.
AGA-8 Supercompressibility Gross Method 2
The EFC is configured with values for
specific gravity and mol percent of N2 and
CO2.
Vc = Vu x (Pm + Pa) x Tb + 459.67 x (Fpv)2
Pb
Tm + 459.67
Where:
Vc = Volume corrected to base conditions
Vu = Uncorrected line volume
Pm = Measured line pressure (psig)
Pa = Atmospheric pressure
Pb = Base pressure
Tb = Base temperature (0F)
Tm = Measured line temperature (0F)
Fpv = Supercompressibility factor
The unit makes continuous correction for the
specified gas composition based on actual
sensed pressure and temperature.
NOTE
All of the AGA factors can be based on either
flowing or constant values.
The supercompressibility factor can be
calculated from either NX-19 or AGA-8
Gross Methods 1 and 2 reports and applied to
the volume equation.
NX19 Supercompressibility Report
The EFC is configured with values for
specific gravity, mol percent of N2 and CO2.

MTEK6000 SERIES USER'S MANUAL
To enable analog sampling, set this parameter
to 1-99 seconds. Set to 0 to disable analog
sampling.
APPENDIX C:
PARAMETER DESCRIPTION
The parameters relative to the operation and
configuration of the MTEK6000 are listed
below (See Appendix A for the addresses of
these parameters).
Atmospheric Pressure
If the station is configured for ABSOLUTE
pressure, enter 0.
atmospheric pressure for GAUGE pressure.
The default value is 14.4 PSI for gauge and 0
for absolute.
Enter the actual
Alarm Pulse Output Enable/Disable
The EFC can generate a generic pulse output
on any alarm condition. This parameter
enables the pulse output through Relay #2.
Enter 35.7 to enable or 0.0 to disable. The
Default value is 0.
Audit Trail Logging Enable
This parameter enables Audit Trail logging in
the MTEK6000. Examples of audit trail
events include editing any item at the device,
and logging the time it enters calibration
mode. After the maximum number of events
(250) has been logged, no more parameters
can be changed in the unit until the audit trail
is uploaded and reset by the software. This
parameter is disabled at the factory. The user
may enable Audit Trail logging by entering
250. Default value is 0 for disable.
Alarm Pulse Time (ms)
This parameter sets the output band width in
milliseconds (ms) for pulse outputs generated
by an alarm condition. The user should take
care in assigning a value for this parameter.
The value should always be less than the
Wakeup Interval Parameter; else the unit will
stay awake for the duration of the pulse.
Range 0 to 32,000 ms. The Default value is
70.
NOTE
Once the audit trail is enabled, the user cannot
disable it without reloading the database.
Analog Sampling Rate (seconds)
This parameter sets the rate at which the unit
will sample its dynamic analog input variable
channels. When enabled, the unit samples
pressure, flow temperature, case temperature
and the external analog transmitters values
once for each selected interval.
Base Pressure
The Base Pressure parameter appears as a
factor in the Corrected Volume calculation. It
is one of the factors used to correct the
flowing volume, as registered by the meter
itself, to the base volume used for calculating
“Standard Volume”. The normal pressure
ranges for this parameter are 11.000 to 16.000
PSI.
The sample’s minimum and maximum values
are then checked against their corresponding
High and Low Setpoints.
If the unit
determines that these conditions were
exceeded, it “wakes up” and finds the average
of all samples accumulated since the last
process execution, displays this analog mean,
and applies it to any necessary subsequent
calculation.
The standard value for this parameter is
14.730 PSIA, 101.560 kPa, or 1.114 kg/cm2,
depending upon the system of units chosen
for the particular device. Default value is
14.73.

factor in the Corrected Volume calculation. It
is one of the factors used to correct the
flowing volume, as registered by the meter
itself, to the base volume used for calculating
“Standard Volume”. The default value of this
parameter is 60.000 degrees F.
The corrected volume is calculated based
upon AGA report #7 or #8 and reflects the
corrected volumetric flow taking the base
conditions into consideration. The Initial
value is 0.
Corrected Volume (Pressure Only)
The corrected volume is calculated based
upon AGA report #7 and reflects the
corrected volumetric flow taking only the
Pressure base conditions into consideration.
The temperature factors have no effect. The
Initial value is 0.
Calibrate Mode Time-out
The fractional portion of this parameter is the
Calibrate Mode Time-out. It controls how
long the unit will remain powered up in the
calibration mode if no key is being pressed.
For example, a calibration time-out of 30
minutes would be entered as XX.30. The
default value is 60.30.
Corrected Volume and Flow Multiplier
This multiplier specifies the output value for
corrected volume and flow. For example, if
the device is to measure flow in thousands of
cubic feet (MCF), select Thousands (1000's)
of units from the pick list. The Default value
is 1000.
Calibration Password
A password can be entered to prevent
unauthorized users from accessing calibration
mode. The value may be up to six digits long
(including the decimal point and sign). The
Default value is 0.

Counter Fault Monitoring (EFC Only)
This parameter can be used to enable or
disable fault monitoring on the main counter
#1. Form C (3-wire) input is required for this
function. In this mode, two working counters
are monitored for discrepancies. A “Delta”
value will be accumulated which reflects any
discrepancies between the counters. If any of
the dual-reed switches should be defective,
and the “Delta” exceeds the Counter Fault
Threshold parameter, the input pulses will
automatically switch to either working single-
ended counter. The EFC will generate a
Faulty Counter alarm. To enable, set this
parameter to 1 and to disable set to 0. The
default value is 0 for disable.
Corrected Pulse Output -Cubic Unit / Pulse
This parameter should reflect the value of the
corrected pulse output sent from the station to
an external device. For example, if each
output pulse represents 1000 cubic feet, then
this parameter should be set to 1000. The
Default value is 1000.
Corrected Pulse Out Enable/Disable
Corrected pulses can be sent to an external
device by enabling the Pulse Output Channel.
The rate at which pulses are generated is
determined by the Corrected Pulse Out - CF
per Pulse parameter. To enable Relay #1 for
pulse output, enter a value of 35.8. Enter -1
to disable. The Default value is -1.

MTEK6000 SERIES USER'S MANUAL
Cubic Unit/Pulse In or Meter Drive
Date (Month, Day, Year)
This parameter determines the volume unit
represented by one input pulse, and is
normally set to equal the drive (CF/Rev) of
the meter. Standard indexes produce one
pulse per revolution; therefore, the CF/Pulse
will equal the drive rate of the meter. The
Default value is 100.
This is the current Date in the unit
(MMDDYY). It is updated on each process
scan.
Flow Rate Update Interval (s)
This parameter determines how often the flow
rate gets updated in the EFC. However, it has
no control over Volume updates. Volume is
updated every time the unit wakes up from
the sleep mode or every 3-4 seconds if the
unit is always awake.
For instruments utilizing remote pulsing
devices, this value can also be determined by
dividing the CF/Rev of the meter by the
number of pulses per revolution generated by
the remote pulser.
The Flow Rate Update Interval parameter is
of the form XXX.YY.M where the integer
portion (XXX) is the time interval in seconds
between Flow Rate updates. The digits after
the decimal point (YY.M) represent the zero-
flow period (i.e. the amount of time to wait
without receiving pulses before generating a
zero flow rate). The first two digits are
minutes and the third digit (T) is a fraction of
a minute. Thus, a two-minute zero-flow
period would be entered as XXX.020, a ten
minute period as XXX.10. The maximum
allowed period is 27 minutes and the default
is one minute (XXX.010).
For example: Consider a 3GT meter with a
100 CF/Rev drive and a 50 Pulse/Rev Imac
Pulsamatic Transmitter. The CF/Pulse is
determined as follows:
CF/Pulse = 100 CF/Rev * 1 Rev/50 Pulses
= 2 CF/Pulse
NOTE FOR METERS WITH 5 CF/REV
DRIVE RATES:
Re-position the input compound gear to the
correct position, and set this parameter to a
value of 10. Refer to Section Two or contact
Metretek, Inc. for assistance in positioning the
compound gear.
The user MUST specify a zero-flow period,
which is larger than or equal to the Flow Rate
Update Interval. Specifying a zero-flow
period smaller than the Flow Rate Update
Interval will result in a zero-flow rate being
displayed even when there is an apparent
flow. For example: A value of 600.11 would
update flow rate every 10 minutes and display
zero flow if 11 minutes passed without an
input pulse. A value of 600.01 will not work
properly. It would try to update flow rate
every 10 minutes, but would zero the flow
rate every minute, even if pulses come in
faster than one per minute.
Current Day High Volume Alarm Reset
After the Current Day's Total is exceeded, the
setpoint at which the unit exits this condition
is entered in this location. The Default value
is 99,990.

Setpoint
This parameter specifies the setpoint at which
the unit determines whether the Current Day
Flow Total is in an alarm condition. For

100,000.
