Introduction

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.
Features
− For secondary applications
− With electronic totalizing unit
− Flow display
− Display of maximum flow values
− Alarm output
− Detachable meter head (for use as a remote totalizer)
− Digital transmission of meter readings
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
