4 to 20mA Integrated Small Blind Zone Ultrasonic Level Meter LED Display Ultrasonic Sensor Non contact Level Measurement Device

When installing the ultrasonic level gauge, it should be noted that the installation should be perpendicular to the surface of the object, avoiding the use of objects for measuring foam properties, and avoiding the distance from the surface of the measuring object to be less than the dead zone distance. Meet the container wall, detect large solid objects should adjust the probe orientation, reduce measurement error
