Introductions
WESDUN is a manufacturer specializing in the production of Wall-mounted ultrasonic flow meter;Clamp-on ultrasonic flow meter. WESDUN ultrasonic flow meter is a wall-mount, clamp-on or insertion type ultrasonic flow meter using transit-time technology.
Both Clamp on type sensors and Insertion type sensors are available. New designed using advanced chip and low-voltage broadband pulse transmission, ensure flow meter with high accuracy and repeatability for long term operation.
