Applications - Ultrasonic
Ultrasonic transmitters are very popular because they are not in contact with the liquid. They transmit a pulse which bounces off the media and returns to the sensor. The time taken to send and receive the signal is measured.
Consideration needs to be given to the location of the transmitter to ensure that external influences will not affect the signal
Below are some simple diagrams to show the System Applications of Ultrasonic Level Controls.
