When it comes to determining the level of liquid, many different industries rely on sensors. Although those that use radar to operate remain popular, others are just as advantageous. A perfect example of that is the ultrasonic level sensor.
What are Ultrasonic Water Level Sensors?
To start with, ultrasonic liquid level sensors operate in a very specific way. These sensors emit a burst of sound waves in extremely fast succession. The sound waves travel to a designated target. Upon reaching it, they bounce off, followed by returning to the sensor.
The amount of time that it takes the bursts of sound to retreat to the sensor is how the distance between the sensor and the liquid gets calculated. Keep in mind that an ultrasonic level sensor typically has several parameters programmed in. Those include weight, volume, and other measurements. The program uses all those to make precise calculations.
Ultrasonic water level sensors accurately determine the level of fluid. However, to do this, they require zero obstructions in the air column that goes between the sensor and target. So, if anything like dust, light powders, heavy foam, or vapors exists, the sensor won’t operate correctly. These factors could also cause the sensor to give a false reading.
Common Uses for Ultrasonic Level Sensors:-
• Liquid Level Measurement – A sensor like this often measures the level in a body of liquid, whether a tank, lake, pit, well, and so on. The sensor can measure liquid in non-linear vessels as well
• Solids Level Measurement – Ultrasonic water level sensors also work well for measuring the level of solids. While some companies prefer a radar sensor, one that operates with sound waves actually does a better job. For this, the key is to make sure the environment has little to no air particles. Otherwise, the sensor could give a false reading
• Open Channel Flow – This is another use for ultrasonic liquid level sensors. Often associated with irrigation canals, water treatment facilities, and environmental monitoring situations, an open canal allows for the filtering, transporting, and metering of water
• Object Detection and Profiling – Perhaps one of the remarkable benefits of these sensors is their ability to detect and profile different objects. For optimal results, companies use this type of sensor in either wet or dirty environments with slow-moving objects. Unlike radar, ultrasonic water level sensors do well in harsh conditions
