Elements for good practice and installation examples
We propose here, and without being exhaustive, some elements of good practice such as:
- The sensor have to front and be perpendicular to the surface water to be measured. This surface has to be stable and
without ripples for more accuracy, without foam). If possible it shouldn’t be any obstacle between the sensor and the
water surface (if you can’t avoid it, please refer to the calibration chapter to mask it with a filter).
- The calibration is compulsory and the verification of the max distance (Z) very important.
Calibration has to be checked at least once a year.
- Sensors with ultrasonic technology don’t need much maintenance, but at least once every six months you should clean
it, check on-site the presence of debris, floating debris, anything hang to the sensor
