FIELD: instrumentation.
SUBSTANCE: ultrasonic dirt sensor (UDS) contains a metal corrosion-proof flange with holes and fittings for tight fastening to a tank wall, on the flange a waterproof electronic unit with ultrasonic receivers and ultrasonic radiators connected by conductors laid with leak-tightness inside guides of measuring and bearing channels is fixed and the vessel (barrel) of the bearing channel made of thin corrosion-proof metal, while the vessel (barrel) of the bearing channel is filled with clean distilled water only once by a manufacturer and hermetically soldered.
EFFECT: simplification in service, improvement of reliability, safety of the sensor operation, improvement of accuracy of measurements of water pollution and expansion of scope of application.
