Once the sensor has been installed and electronically connected, it is possible to measure the filling height via the service opening of the mounting plate, for example with a dip stick.
This process should be performed with an ongoing slide, because the sensor only measures the level of the surface on a moving flow.
The measured filling height serves as a value of calibration for the sensor.
If the density of fluidization is supposed to be used for a calculation of the flow signal, the filling height at a turned off conveying has to be known.
After the input of the parameter, the sensor gives out a trend signal for the flow rate.
Flow-/ No Flow conditions are also reliable identified.
