The DFM 6.1 Doppler Flow Meter is a non-contacting, clamp-on flow meter that uses Doppler technology for effective pipe flow measurement.
The DFM 6.1 Doppler Flow Meter is a non-contacting, clamp-on flow meter that uses Doppler technology for effective pipe flow measurement. It is suitable for liquids with suspended solids like wastewater, slurries, and chemicals. The meter is easy to install without interrupting the flow system and offers features such as a digital flow rate display, data logger, and control relays. It can measure flow in either direction and is ideal for controlling flow within a process or testing existing equipment for accurate flow measurement.

The DFM 6.1 is listed as a clamp-on ultrasonic Doppler flow meter for full pipes and difficult liquids, including wastewater, slurries and liquids containing suspended solids. Its non-contacting approach can be considered where the pipe outer wall is accessible.
Before requesting a configuration, provide the process medium, pipe or channel details, normal and maximum operating range, installation access, temporary or permanent requirement and the output or communication needed by the receiving system. Photographs, drawings and existing nameplate details are useful for replacement or retrofit enquiries.
Compare this model with the ultrasonic flow meter selection guide and the Pulsar Measurement product range to confirm the measurement approach.
When should Doppler be considered instead of transit-time? Doppler may be a better starting point where the liquid contains suspended solids or bubbles. The final choice depends on the actual liquid and pipe conditions.
