ABSTRACT:
A method for cleaning the sensing probes in a water quality momitoring apparatus, when the probes become coated with a build-up of slime, algae or particulate matter, which comprises the steps of continuously removing particulate matter from the body of the liquid, moving a part of the body of liquid into a confined zone surrounding the probe and applying ultrasonic energy to the confined liquid to remove deposits of foreign matter from the surface of the probe and the liquid confining surface areas.
