Introducing the C6™ Ultrasonic Doppler Flow Meter

The C6™ ultrasonic doppler flow meter is a non-contact portable flow meter suitable for liquids with high concentration of suspended solids or aeration. The C6 doppler flow meter is perfect for sewage sludge, slurries, aerated liquids, raw sewage, dredges, pulp, plastics, and wastewater.

When you need a reliable portable ultrasonic doppler flow meter, the C6™ is the right choice. This flow meter has been tested in the field for the last 30 years. The Compu-Flow™ Doppler ultrasonic flow meter provides an accurate and easy-to-use measuring system for high-solid fluid flow through pipes with inside diameters ranging from 0.50 inches to 999 inches.

Doppler Flow Meter Working Principle

The Doppler principle, discovered by Christian Doppler in 1842, explains the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source. In Doppler flow meters, the principle is used to measure the velocity of a fluid within a pipe. Here’s a simplified explanation:

1. An ultrasonic transducer emits waves into the fluid.
2. These waves reflect off particles or bubbles in the fluid.
3. The reflected waves return to the transducer with a frequency shift.
4. The device analyzes this shift to calculate fluid velocity.
5. Combined with the cross-sectional area of the pipe, the flow rate is determined.
