MTEK6000 SERIES USER'S MANUAL

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.
