ULS-02 & ULS-06
Ultrasonic Level Sensor
The ULS-02 ultrasonic level sensor transmits series of ultrasonic pulses which propagate towards the liquid surface. The reflected acoustic wave is received back in the ULS-02 transducer and processed in the electronic module. The distances calculations are based on time flight of the acoustic wave to the level and back.
The ULS-02 and ULS-06 sensors can easily be combined with the new generation open channel non-contact RAVEN-EYE® radar velocity sensor and constitute a custom-tailored non-contact open channel area/velocity flowmeter.
The ULS sensors are ultrasonic level sensors providing continuous level measurement of liquids like water and wastewater. They are self-contained units that include the electroacoustic transducer and the electronic module.
The ULS-02 and ULS-06 level sensors are suited to continuous non-contact level measurement of liquid in closed conduit or open channel applications.
