As the name indicates, ultrasonic / level sensors measure distance by using ultrasonic waves. The sensor head emits an ultrasonic wave and receives the wave reflected back from the target. ultrasonic / level sensors measure the distance to the target by measuring the time between the emission and reception.
A radar liquid level sensor is an instrument for measuring the height of a liquid and converting it to an electrical signal. Radar liquid level sensor technology transmits a high frequency electromagnetic wave pulse typically in the microwave spectrum, and receives the wave reflected off a liquid surface.
