Key Features

●    High measurement accuracy: The multi-hole structure design balances the flow field, reduces vortices, vibrations and signal noise, improving the flow field stability. The accuracy is ±0.25-0.5% with actual flow calibration.

●    Low straight run requirement: The flow element serves as a conditioner, adjusts the uneven flow to uniform flow, shortening the straight run requirement to 0.5D upstream- 2D downstream. 

●    Low permanent pressure loss: The BVFM reduces vortices and turbulent friction, lowering kinetic energy loss. Pressure loss is 70% less than traditional Orifice, close to Venturi tube.

●    Wide turndown ratio: Standard measurement range ratio is 10:1, can reach to 30:1-50:1 with multiple transmitters. 

●    Good repeatability and stability: The repeatability of the balanced flow sensor is ±0.1%. Multiple flow holes evenly distribute force. No moving parts results in 5-10 times longer life than traditional orifice.

●    Resistant to dirt and clogging: Multi-hole symmetrical design reduces turbulence, minimizes dead zones, allows dirty media to pass, reduces clogging. 

●    Wide measurement range: The BVFM covers flow velocity from minimum to sonic speed, with Reynolds number range from below 200 to above 10^7.

●    Energy and cost saving: The overall energy and cost saved by BVFM from its low pressure loss, short pipe run, high process control accuracy , and long service life 

●    Application scope: The BVFM can satisfy almost all the insdutrial measurement applications. It can measure gas-liquid two-phase, corrosive, slurry or fluid with solid particles. The A+X Balanced Venturi Flow Meter can also measure bidirectional flow.
