FIELD: determination of angles of deviation of various objects from vertical line. SUBSTANCE: transducer includes case 1 with cylindrical chamber filled with two immiscible liquids 2 and 3 having different densities and taken in equal proportions. Radiator 5 and ultrasonic receiver 6 are placed at angle of 45 deg to plane of base of case. Radiator 5 is connected to output of generator 7 and receiver 6 to module 8 of preliminary signal processing and amplitude detector 9 connected in series. Boundary of separation 4 of liquids is used in the capacity of reflector of ultrasound. EFFECT: simplified design, increased functional reliability. 1 dwg
