10.3.3
Troubleshooting sensor-related problems
Incorrect and unstable measurements, especially at low flows, are typically a result of an
unstable zero point due to:
● Incorrect installation
● Bubbles in the liquid
● Vibrations or cross talk
● Solid particles settling in the liquid
Follow the 4-step guide to troubleshooting:
Step 1
Preliminary application inspection (Page 190)
Step 2
Zero point adjustment (Page 190)
Step 3
Measurement error calculation (Page 190)
Step 4
Application improvement (Page 190)
The guide enables you to trace the reason for incorrect measurements and to improve the
application.
Step 1: Inspecting the application
Ensure that:
1. The sensor is installed as described in Installing/mounting (Page 37).
2. The sensor is located in a vibration-free position. Vibrations can disturb the sensor and
therefore cause measurement error.
