MTEK6000 SERIES USER'S MANUAL
January 2002 1 - 1
CHAPTER 1: OVERVIEW
NOTE: The MTEK6000 is similar in
many respects to the Metretek AE6000
but there are also differences. The
information in this manual applies only to
the MTEK6000.
The MTEK6000 series products are low-
cost microprocessor-controlled, electronic
devices for measuring gas flow and volumes
or monitoring pressure and temperature for a
system. With integral pressure and
temperature transducers, the MTEK6000 is
designed for accuracy, reliability, and ease
of maintenance. It can mount directly on a
meter's index plate, on a wall or pipe.
Low-power CMOS design and sophisticated
power conservation circuitry allow the
MTEK6000 to operate one to two years on
battery power.
Two pulse inputs, two status inputs, two
pulse outputs, two external analog inputs
(4-20 mA or 1-5V) and a tamper input are
standard. A large 13-digit LCD display,
with a magnetic scroll switch located on the
enclosure exterior, permits data viewing
without opening the enclosure. Station
parameter display and alarm display can be
performed with only external device. The
standard internal 2400/1200/300 baud
modem provides remote configuration,
calibration, and retrieval of data.
The operator can also use an industry-
standard portable computer running
Metretek software to configure parameters.
See Chapter 5 for information on these
packages. The MTEK6000 calculates
corrected volume using AGA-7, AGA-3,
AGA-5 and NX-9 or AGA-8 reports.
Optional equipment includes an external
keypad and display for configuration and
calibration, analog output modules, two
additional pulse outputs, serial port modules,
and various security options.
The MTEK6000 product line consists of six
models that cover a wide range of
applications.
• The MTEK6000 EFCV provides a live
pressure and temperature reading in
volume corrections for Positive
Displacement meters (turbine, etc.)
• The MTEK6000 EFCP provides a live
pressure and a fixed temperature reading
in volume corrections for Positive
Displacement meters (turbine, etc.)
• The MTEK6000 EFM provides a live
pressure and temperature reading in
volume corrections for Orifice meters.
• The MTEK6000 EPR provides a live
pressure reading for monitoring systems.
• The MTEK6000 ETR provides a live
temperature reading for monitoring
systems.
• The MTEK6000 EPTR provides a live
pressure and temperature reading for
monitoring systems.
HAZARDOUS LOCATIONS
The MTEK6000 is listed by Underwriter’s
Laboratories to bear the UL/C-UL mark (US
& Canadian Listing) for use in hazardous
locations.
The intrinsically safe version can be
installed in a Class I, Division 1, Group D
hazardous location when connected through
the intrinsic safety barriers as listed in
control drawing 401061. A copy of this
drawing is shown in appendix E.
The non-incendive version can be installed
in a Class I, Division II, Group D hazardous
location when installed in accordance with
control drawing 401060.
This drawing is also listed in Appendix E.
