Remedy
1. Check supply voltage
2. Replace MASS 6000
1. Activate current output
2. Activate digital output
3. Change direction
Ensure that the measuring
pipe is full
Replace MASS 6000

2. Replace MASS 6000
Switch off MASS 6000,
wait 5 s and switch on again
Select empty pipe limit
Ensure that the measuring
pipe is full of liquid
1. Increase time constant
2. Ensure medium does not
contain air bubbles
3. Ensure that the sensor is
mounted on a rigid frame
without vibrations
4. Ensure that pump frequency
is different from resonance
