Transmitters

Various transmitters with various connections and communications can be con-
nected to the ERZ2000-DI and bus connections. This normally takes place via the
wizard and supports pre-settings that often only have to be acknowledged.

4.1 Flow meters

Basically, the ERZ2000-DI can work with all flow measuring devices that are used
in the flow measurement of gas.

4.1.1

Turbine wheel gas meters

The operating method of turbine wheel gas meters is based on the measurement
of gas speed with a turbine wheel. In the process, the speed of the turbine (ap-
proximately) within the measuring range (Q

min

- Q

max

) is proportional to the mean

gas speed and thus the flow rate. The number of rotations, therefore, is a meas-
urement for the gas volume flowing through.
