MTEK6000 SERIES USER'S MANUAL

TRANSDUCERS IN THE MTEK6000

The MTEK6000 uses a precision strain gauge pressure transducer mounted inside the unit, combining maximum accuracy with low

power consumption. To sense gas temperature, the MTEK6000 employs a highly linear and stable device, a platinum resistive temperature detector (RTD). Case temperature sensing is accomplished with an on-board precision reference integrated circuit (IC).

CONNECTING THE PRESSURE TUBING

WARNING

You must DEPRESSURIZE THE METER and its associated piping before you make pressure piping connections. FAILURE to do so may result in EXPLOSION and FIRE, causing SERIOUS PERSONAL INJURY and PROPERTY DAMAGE.

Do NOT attempt to connect any piping or fittings to a meter or pipe under pressure.

Do NOT SMOKE while connecting gas or test pressure to the meter.

Note

Federal Standard 192.02 requires a shut-off valve between the pressure source and the instrument. A needle valve is supplied with the optional pressure piping kit for this purpose. Its rating is 1,500 PSIG MAOP.

Figure 2- 5 Pressure Connections

As a minimum requirement, connect the pressure tubing as shown in Fig. 2-7. An optional pressure tubing connection kit (part # 2019-0009B-001) can be shipped with each instrument. Fig. 2-8 is the recommended pressure installation for ease of operation. Additional piping and valve are required for the installation and are not supplied. Use Teflon tape or pipe seal compound on all threaded connections. The tubing supplied in the kit may be longer than you need for your installation. You can cut or coil the tubing, but do not make any sharp bends in it (minimum radius is 3/4"). Tighten all the connections and perform a leak test once the meter and instrument are pressurized.
