Reynolds Number
| A Reynolds number is a parameter describing flow velocity, viscosity, and pipeline size. To maintain system accuracy, a Reynolds number >10000 is required. To calculate the Reynolds number, use the following formula: | Reynolds
number = DV/u D = internal pipe diameter (m) V = flow velocity (m/s) u = kinematic viscosity (m2/s) Water (u) = 1·10-6m2/s |
Backpressure Calculation
Minimum downstream pipe backpressure levels are required to prevent cavitation within the sensor. The minimum back pressure is calculated by the following formula: 2.7P + 1.3 x Po (P = Pressure drop across sensor. Po = Water saturation vapor pressure at operating temperature.)
