In Ultrasonic Level Measurement, the sensor emits ultrasonic pulses in the direction of the medium, which then reflects back to the sensor. The elapsed time from the emission to the reception of the signals are proportional to
the levels in the tank. Ultrasonic sensors are ideal for simple standard applications where Intrusive Level Instrumentation cannot be installed.
Signals from the transducer are fed into the processor and then processed by patented algorithms to calculate the height of the liquid according to the formula.
