Open Channel Doppler Flow Velocity Meter (battery powered)

Open Channel Area Velocity Flow Meter - Battery Powered

Portable flow monitoring for open channels and partially filled pipes

The BFU-300 battery powered open channel Doppler flow meter is designed for measuring flow in open channels, sewers, culverts and partially filled pipes without requiring a flume or weir. It is a practical solution for temporary surveys, wastewater monitoring, stormwater studies, effluent checks and remote sites where mains power is not available.

Designed for difficult flow conditions

Using area velocity measurement, the instrument measures both water level and flow velocity, then calculates flow rate based on the channel or pipe profile. This makes it especially useful where traditional primary devices are not practical, or where installation time, civil work and site disruption must be kept to a minimum.

Portable battery-powered operation

The battery powered design makes the BFU-300 well suited for field technicians, municipalities, environmental consultants and industrial facilities that need reliable flow data from remote or hard-to-access locations. It can be used for short-term investigations, compliance checks, inflow and infiltration studies, and general wastewater or surface-water monitoring.

Q&A

What is a battery powered open channel flow meter used for?

A battery powered open channel flow meter is used to measure flow in open channels, sewers, culverts and partially filled pipes where permanent power may not be available. It is commonly used for wastewater, stormwater, industrial effluent and environmental monitoring.

Does an open channel Doppler flow meter need a flume or weir?

In suitable installations, an area velocity Doppler flow meter can measure flow without a flume or weir. This can reduce installation cost and make the system easier to deploy in existing channels or partially filled pipes.

What is the advantage of area velocity flow measurement?

Area velocity measurement combines water level and velocity readings to calculate flow. This is useful in applications where flow conditions change, where the pipe is only partially full, or where installing a primary measurement structure is not practical.

Where should the sensor be installed?

The sensor should be installed in a stable section of the channel or pipe where the flow profile is representative and not heavily disturbed by bends, obstructions, turbulence or sediment buildup. Correct placement is important for reliable flow data.

Is this type of flow meter suitable for wastewater?

Yes, Doppler area velocity flow meters are commonly used in wastewater and sewer monitoring because they can work in fluids that contain suspended particles or bubbles, which help produce the Doppler signal.
