5.2.4 Level measurement
• Always mount the device below the lowest measuring point
• Do not install the device at the following positions:
• In the filling curtain
• In the tank outlet
• In the suction area of a pump
• At a point in the tank which could be affected by pressure pulses from the agitator
• Mount the device downstream from a shutoff device: the calibration and function check can
be carried out more easily
