RMG TERZ 94 94-S turbine meter

The TERZ 94 / 94-S turbine meter complements the RMG TRZ 03, TRZ 03-L and TRZ 03 K turbine meters (see RMG Publication Nos. 3.161-E and 3.171-E). The TERZ 94 / 94-S directly measures the flow rate at measurement conditions and integrates the measured values, so that, as a result, the gas volume which flowed through the meter is registered by an electronic totalizing unit. The gas flow drives a turbine wheel whose speed is recorded through non-contact measurement by a sensor. Therefore, the meter is characterized by long-term stability and low wear. The TERZ 94 / 94-S is provided with HF and LF outputs which allow the device to be used as a flow transducer for control applications and remote transmission. 

The two variants TERZ 94 and TERZ 94-S differ in the following features:

TERZ 94

 Battery operation

 Electronic suppression of the slow-down effect of the turbine wheel after flow stop by external shut-down of the totalizer

TERZ 94-S

 External power supply

 4-20 mA current output for outputting the flow rate

Electrical connections

The LF and HF volume pulses and the alarm output are led out of the meter head by a 7-pin connector (Binder). All other connections have to be made at the terminals on the board.
