MAINTENANCE
5.1 STORING AND CLEANING OF THE SENSOR
Ultrasonic level sensors do not require any special maintenance, however, the bottom
of the sensor must not be covered by sediments. If necesary the sensor can be easily
cleaned using a soft bristled brush and detergent compatible with PVDF. Do not use
harsh abrasive brushes or solutions which may damage the PVDF sensor enclosure.
Ensure that the tank / pipe does not contain any fluid or pressure before
dismounting.
