What Does Sonar Measure in a Lift Station?

Explanation:
Sonar in a lift station is used to measure liquid level by determining how deep the wastewater is. The sensor sends a sound pulse toward the surface, hears the echo when it reflects off the liquid, and measures how long the round trip takes. Using the speed of sound in the surrounding gas and the time of flight, the system calculates the distance from the transducer to the liquid surface, which is the liquid depth. That depth reading is essential for controlling pumps and triggering alarms. Flow rate isn’t obtained directly from sonar, and temperature or pressure aren’t what the sonar measurement provides.
