NIVOLIC WL Water Level Sensor
HIGH ACCURACY
HIGH RESOLUTION
LONG TERM RELIABILITY
The NIVOLIC WL, when combined with a weir, allows monitoring of water flow. It is commonly used for assessing performance of dams
The NIVOLIC WL consists of a chamber in which a cylindrical weight is suspended from a vibrating wire transducer. The cylinder hangs partially in the water which level has to be monitored.
Changes in the water level of the chamber modify the buoyancy force acting on the weight, thus modifying the tension and the resonant frequency of the vibrating wire. A thermistor is integrated in the gauge, enabling measure of temperature.
