FE951 Clamp-on Ultrasonic Flow Meter
Summary:
The FE951 clamp-on ultrasonic flow sensor features a compact footprint and requires no external circuitry for measurement and output. The sensor is directly clamped onto the exterior of rigid plastic pipes to provide precise measurements of the fluid flow inside. Since the sensor does not come into direct contact with the fluid in the pipeline, it does not contaminate the fluid, making it particularly well suited for applications with stringent hygiene and cleanliness requirements—such as liquid flow monitoring in medical devices, biopharmaceuticals, industrial automation, new energy, and semiconductor industries.
