音波式液面レベルセンサ。The sensor is mounted on the bottom wall of a tank containing a liquid using a waterproof structure that emits ultrasonic pulses to a stopper that fits liquid-tightly to a member and a support that is installed upright on the stopper. A transducer and a waterproof ultrasonic receiver that generates electrical signals in response to emitted ultrasonic pulses are held so that their transmitting and receiving surfaces face each other at a predetermined distance. When the stopper is fitted to the sensor mounting member of the tank, either the ultrasonic transmitter or the receiver should be above the liquid level line that is to be detected in the liquid, and the other should be In the device configured to face the lower level line, the edge of either the next wave surface of the ultrasonic transmitter or the receiving surface of the ultrasonic receiver located above the level line is An ultrasonic liquid level sensor characterized by a semicircular arc shape with curvature.
