In Lift Station Monitoring, What Measurement Does Sonar Provide?

Explanation:
Sonar in lift station monitoring provides a depth measurement—the distance from the sensor to the wastewater surface. It works by sending a sound pulse down into the wet well and timing how long the echo takes to come back. That time is converted into distance, which is the depth of the liquid below the sensor. This value changes as the wet well fills or drains. To get a traditional level reading, you’d convert this depth using the sensor’s mounting height or the well’s geometry, but the direct output from the sonar is the depth. Temperature and velocity aren’t measured by this sonar measurement, which is why those options aren’t correct.
