Ultrasonic Level Measurement In Water And Wastewater Plants

By Tim Thomas, Level Product Business Manager, Endress+Hauser, Inc.

Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry. Although radar technology certainly does offer high performance and accuracy, in many water and wastewater applications non-contact level measurement using ultrasonic is the best choice due to its lower cost and application-specific benefits. This paper will compare ultrasonic and radar sensors, and provide examples where ultrasonic instruments are the best choice.
