FIELD: measurement equipment.
SUBSTANCE: media interface sensor (MIS) for an oil-water filtering plant (OWFP) comprises a bronze flange with holes and accessories for a tight fixation to a cover or a bottom of a reservoir; on the flange there is a water-impermeable electronic unit fixed, stands of a measurement channel. With the electronic unit, using tightly installed conductors, there are ultrasonic receivers and ultrasonic radiators in the form of piezoceramic orifices with diameter of ~15÷18 mm and thickness of ~1.5÷3 mm. To seal piezoceramics, they use silcast or polyurethane. The electronic unit continuously monitors speed of passage and amplitude of ultrasonic pulses in the controlled medium. The sensor does not contain threaded joints.
EFFECT: simplified service, higher reliability and safety of sensor operation.
