音波レベル計。 In a level meter that uses an ultrasonic pulse echo method to measure the air propagation time to the surface of an object to be measured to measure the surface level, a detection probe with only a transmitter is installed, and the A reflecting plate is installed in front of the radiation direction so that the radiation direction of the radiated ultrasound beam is substantially parallel to the surface, and the radiated ultrasound beam is reflected at a substantially right angle and is perpendicularly incident on the surface, and The distance from the transmitter to the surface of the object to be measured is made slightly larger than the dead zone, and another detection probe having only a receiver is installed in front of the reflector and facing the surface. An ultrasonic level meter characterized in that level measurement is performed by making a reflected ultrasonic beam from a surface enter a receiver of the another detection probe.
