Ultrasonic Level Sensors

Ultrasonic level sensors measure the distance to a surface, such as the top of a liquid in a tank, using ultrasonic waves. They emit high-frequency sound pulses that bounce off the surface and return to the sensor. By calculating the time taken for the sound to return, the device determines the level of the substance. These sensors are non-contact, reliable, and suitable for various liquids and solids. They are widely used in industries like water treatment, food processing, and manufacturing to monitor and control levels efficiently.
