In the pharmaceutical industry, cleanliness and process safety are critical. A clamp on ultrasonic flow meter is the ideal solution for hygienic flow measurement because it does not require pipe cutting, welding, or direct contact with the process fluid. By using external ultrasonic sensors, a portable ultrasonic flow meter ensures contamination-free and highly accurate flow monitoring in pharmaceutical applications.
What is Clmap on Ultrasonic Flow Meter
The clamp on ultrasonic flow meter is a non-invasive flow measurement device that uses ultrasonic signals to accurately calculate flow velocity through the pipe wall. This type of ultrasonic flow meter operates based on the transit-time (time-difference) measurement principle.
Ultrasonic waves transmitted in the direction of fluid flow travel faster downstream and slower upstream. As a result, the ultrasonic signals experience different propagation times over the same transmission path. By precisely measuring this time difference, the ultrasonic water flow meter calculates the fluid flow velocity and volumetric flow rate with high accuracy.
Unlike traditional inline flow meters, the portable ultrasonic flow meter is installed externally on the pipe surface. This non-contact installation ensures zero interference with the internal flow, no pressure loss, and no risk of contamination.
Because of its hygienic, non-invasive design, the portable ultrasonic flow meter is particularly well-suited for applications where cleanliness, system integrity, and operational safety are critical.
