In continuous level measurement, the filling height in a vessel is repeatedly detected. The measured value is further processed, e.g. as a 4 … 20 mA signal in a PLC or process control system. Indication of the measured value directly on site is also frequently requested.
A wide range of indicating instruments is available for this purpose. Typical applications are measured value indication for level measurement in pump shafts or remote indication for difficult-to-reach measuring points.
