Ultrasonic Level Measurement

3151 Ultraonic Liquid Level Transmitter Measurement Level sensor is a high reliability, high stability, high accuracy and small volume level transmitter with split structure , It is widely used in measuring the liquid height of small inside diameter pump as well as level height of liquid...

Product Details

The ultrasonic level measurement is a digital level meter controlled by a microprocessor. In the measurement, the pulsed ultrasonic wave is emitted by the sensor, and the sound wave is reflected by the liquid surface and received by the same sensor and converted into an electrical signal. Ultrasonic level gauge has automatic power adjustment, temperature compensation, anti-interference and other functions. Due to the non-contact measurement, the measured medium is almost uncontrolled, and can be widely used in various environments such as water environment, acid and alkali, mud, food.
