ABSTRACT:
An ultrasonic liquid level monitoring system includes an ultrasonic transducer unit that is mountable to a tank. The unit has an emitter to generate an ultrasonic beam passing through the wall of the tank. The emitter further receives an echo of the ultrasonic beam off a liquid surface. An acoustic lens is disposed between the emitter and the tank wall to receive and shape the ultrasonic beam to compensate for lensing effects of the tank wall.
