Ultrasonic Level Indicators/Transmitters

Sansel Instruments and Controls offers ultrasonic level indicators/transmitters – ULI 100. An ultrasonic wave is pulsed 2 times a second. The same transducer receives the reflection of this pulse. The time difference between the time of pulse and the reflection corresponds to the distance of the reflecting object from the transducer. Since speed of sound is dependent on the temperature of air, inbuilt temperature sensors monitor and compensate for variation in sound speed over the entire working range. Pump-in/out: the ultrasonic transmitter can be configured for high/low level control applications, wherein the flow into or out of a tank is to be controlled. Conveyor line counter: this ultrasonic transmitter can be used to reliably count the objects moving on a high speed product conveyor line; open channel flow measurement: this ultrasonic transmitter can be used to measure the flow velocity of liquids in an open channel by measuring the water head a trapezoidal/triangular channel; web loop tension: the ultrasonic transmitter can be used to control web speed by monitoring loop tension.
