Ultrasonic Level Indicators

ULI 200 series transmitters are 3 wire type instruments. An ultrasonicwave is pulsed 5 times a second. The reflection of this pulse is received by the sensor. The time taken for the wave to travel to the object and back to the sensor is proportional to the distance of the object from the sensor. The compact size, narrow beam angle and small dead band ensures that these sensors will work reliably for small tanks. These non-contact instruments find a variety ofapplications. Typical applications are measuring level of liquids in small storage tanks and diesel tanks. Other applications include Conveyor line counting, Web loop tension measurement, Open Channel flowmeasurement, collision detection, and more…
