What is an Clamp-On Ultrasonic Flow Meter?

Clamp-on Ultrasonic Flow Meters measure liquid flow from the outside of the pipe instead of cutting into it. They use external sensors that rest on the pipe surface and read flow using sound. Because they stay outside the system, clamp on meters offer a way to measure flow without shutting down equipment, draining lines, or altering existing piping. Their purpose is to deliver accurate flow data while keeping the system sealed and undisturbed.

Clamp on Flow Meters rely on ultrasonic signals that travel through the pipe wall and the liquid inside. Two external sensors send and receive these signals. By looking at how the sound moves through the pipe, the meter can understand the speed and pattern of the flow. The method is non invasive and does not require the meter to come into contact with the liquid. This makes clamp on technology different from inline meters, which must be installed inside the pipe and often require cutting, welding, or system shutdown.
