Radar vs. Ultrasonic Level Sensors: A Selection Guide
In process automation, water management, environmental monitoring, and industrial storage applications, measuring liquid or solid levels is a critical task. Accurate level measurement ensures safety, efficiency, and cost control. Among the various non-contact level measurement technologies, radar sensors and ultrasonic level sensors are the most widely used. Both sensor types are designed to measure the distance from a transmitter to the surface of a medium, but they operate using different principles—electromagnetic waves in the case of radar, and acoustic waves for ultrasonic technology. Each technology has unique strengths and limitations. This article serves as a practical selection guide, comparing ultrasonic...
