Environmental and safety conditions
Optimum use of the HydrINS 2 flow meter requires a suitable measurement environment in order to
avoid as far as possible any environmental disturbances that could affect the measurement.
Hydreka shall not be held liable for the quality of the measurements performed using the HydrINS 2 /
HydrINS 2 Mini flow meter if the recommendations given below are not observed.

Conditions in the measurement environment
Protection:
IP 68 (NEMA 6):
HydrINS 2:
72 hours under 10 metres (32.8 feet)
Display units:
72 hours under 2 metres (6.56 feet)

Measured velocity Vm
Q = A × Fi × Fp × Vm
Where:
Q: flow rate
A: internal cross-section (calculated by Winfluid software from the inside diameter,
DI)
Fi: insertion factor (calculated by the Winfluid software)
Fp: profile factor (calculated by the Winfluid software)
Vm: measured velocity
