Deep Well Monitoring - Endress+Hauser Rma 421 Bedienungsanleitung

6.2 Deep well monitoring

The water depth relative to the distance of the water surface to
the well entry at ground level in a deep well is to be measured
and displayed. Additionally the filling sequence is to be
displayed on the bargraph between 0% and 100% and
retransmitted to a data recorder as a 0 - 10 V signal. f the
system becomes faulty then the analogue output is to transmit
the 0% value.
