integrated ultrasonic fuel level sensor with display for water diesel petro palm oil generator fuel tank range 1.2m rs232

the ultrasonic fuel consumption sensor is bonded to the middle of the bottom surface of the box body, and the ultrasonic ceramic wafer layer in the sensor is driven by an external excitation source, and the time difference of the mechanical wave reflected from the original mechanical wave and the liquid interface is received, and the ultrasonic sound speed is used to realize the inner body of the box. the liquid level is initially measured.
