VENBFLOW HYDRO TURBINE DISCHARGE MANAGEMENT
VenBFlow is a new innovation method by TNBR that use very old fluid mechanic principles (Bernoulli principle) and continuity equation. It measures hydro turbine and water intake discharge and is a non intrusive measurement.
VenBFlow measures intake vent shaft or any accessible vent differential head just after intake entrance with respect to stationary water level before intake. It require at least 30cm differential head at full discharge. Recommended measurement resolutions are as follows:
For 30cm max differential = 0.5% of full discharge
For 100cm max differential = 0.17% of full discharge

Benefits
Measurement accuracy: 2%Â
Suitable for efficiency monitoring since it does not introduce head loss
Smallest efficiency degradation can be discriminated <0.5%
Suitable for portable measurement equipment
