The Compu-Flow C6FM is a fixed-mount Doppler ultrasonic flow meter designed for permanent installation on pipes carrying liquids with suspended solids, particles, or entrained air. Its non-invasive clamp-on transducers measure flow through the pipe wall, eliminating the need to cut into the line or interrupt the process. The C6FM uses the CLTV6.5HPC Doppler transducer system and includes a standard 25 ft sensor cable with 4–20 mA output installed and active.
