clamp-on ultrasonic flow meter

M-3100 Series Clamp-On Ultrasonic Flow Meter

The Malema M-3100 Series Clamp-On Ultrasonic Flow Meter is a non-invasive ultrasonic transit-time flow measurement system consisting of the M-3100T Transmitter and M-3150S Clamp-on Ultrasonic Flow Sensor. Designed to measure the fluid velocity of liquid within closed conduit (pipe), the flow meters are installed on the pipe without disrupting the flow path, eliminating risks of leakage or contamination.
