The MCU controller and gap sensor when used together provide an ultrasonic point level liquid switch. Typical applications include sludge blanket level detection in settlement tanks, interface detection for immiscible liquids and contamination detection, such as oil in water or water in oil. The MCU201 and MCU203 control units provide simple and economical control electronics for wall-mounting near a tank or pipeline containing a single ultrasonic gap sensor. The sensors operate on the attenuation of an ultrasonic signal through the fluid.
