Install a pair of measuring probes at the same height of the tank with a distance of 1 m. One probe emits ultrasonic waves and the other receives ultrasonic waves. The transmitting probe emits ultrasonic waves, so that the ultrasonic waves propagate in the medium in the storage tank. In the process of propagation, ultrasonic waves will be attenuated. Finally, the remaining energy will be sent to the receiving probe, and the host computer will judge whether there is liquid through the remaining energy. With liquid, the ultrasonic wave transmission rate is high and the residual energy is low. No liquid, low light transmittance, and more residual energy.
Dinghua electronic external liquid level switch adopts variable frequency ultrasonic technology: ultrasonic signal change detection technology to improve the stability of the switch and make it suitable for various complex field working conditions.
Influencing factors: the tank is made of non-hard material, and the temperature of high-intensity turbulence is -60℃~220℃
