Notice message (!)
EXC. CURR. LIM
# 701
The maximum current value for the measuring tube exciter coils has
been reached since certain fluid characteristics, e.g. high gas or solid
content, are in the limit range. The device continues to work
correctly.
In particular with outgassing fluids and/or increased gas content, the
following measures are recommended to increase system pressure:
1. Install the measuring device downstream of a pump
2. Mount the device at the lowest point in an ascending pipeline
3. Install a valve or an orifice plate downstream from the
measuring device
