For presentation of measured values
With the continuous level measurement, the level in a vessel is detected. The measured value is further processed, e.g. as 4 … 20 mA signal in a PLC or a process control system. Often also the indication of the measured value on site is requested. For this purpose, a wide range of instruments is available. The differences are the kind of indication, the voltage supply and the mounting. Typical applications are measured value indication with a level measurement in a pump shaft or the remote indication on a measurement loop which is difficult to reach such as e.g. a wood chips silo.
