Accurate and easy-to-use measuring system
The Compu-Flow Portable Doppler Ultrasonic Flow Meter provides an accurate and easy-to-use measuring system for high-solid fluid flow through pipes 0.50 inch to 999 inches (inside diameter). The Doppler flow meter is well suited for flow measurement applications such as sludges, slurries, aerated liquids, sewage, dredges, pulp, plastics and activated sludges.
The meter measures flow velocity by sensing signals from reflective materials within a liquid flowing in the pipe. An example of this Doppler Effect is similar to a train whistle – increasing in pitch as the train approaches and decreasing in pitch as the train moves away. To the person riding on the train the pitch remains the same. The increasing pitch is due to phase-front compression and the decreasing pitch is due to phase-front expansion. The flow meter uses this effect to measure the velocity of a liquid through a pipe wall.
