Liquid Level sensors Application:
Liquid level sensors are termed as the sensors used for detecting liquid levels or interfaces between liquids such as water and oil or solids and liquids. These sensors can also be defined as transducers or as integrated systems with instrumentation and control capabilities. This type of liquid level sensor is one of the most important sensors and plays a vital role in variety of industrial and consumer applications. ultrasonic liquid level sensors use ultrasonic technology to generate a high-frequency sound wave to measure the time for the echo to reflect off of the target and return to the ultrasonic liquid level sensor. The distance from the ultrasonic liquid level sensor to the fluid is then calculated based on the speed of sound and the profile programmed into the sensor.
