1 piece 4 to 20ma integrated ultrasonic level meter ultrasonic water level gauge range 15m 24vdc power supply from factory

if the material container contains a stirrer, it will also reflect the ultrasonic signal, causing a false reflection echo and being transmitted to the microprocessor. the microprocessor will process the true mask echoes according to statistical principles, so the echoes that the ultrasonic waves are required to reflect from the surface of the material should be at least three times the echoes reflected from the agitator arms.
