Introduction

General information

Design variants

The EC 21 temperature corrector (correction is made via the temperature measured and a fixed
pressure value) or the EC 24 volume corrector (correction is performed using measured pressure
and temperature values) can be used as a unit together with electronic turbine meters from RMG or
separately with any mechanical turbine or rotary displacement meters.
The following device types are available:

Pulse outputs
There are various hardware configurations for the device types listed:
 without current output:
 with current output (4 to 20 mA): S board
and additional boards for:
 pulse comparison (not available for the TERZ 94)
 RS 485 interface (for Modbus)
 memory submodule with clock
If the corrector is used together with an electronic RMG turbine meter, please observe the
instructions for the measuring element in the annex to this manual!
The operating concept
The operating concept has been chosen in such a way that the operator can easily use the device
without wasting too much time reading a manual.
