What is the Hydrant Pressure Test?
Hydrant pressure tests ensure adequate water supply to fire protection systems – and an Ultrasonic Flow Meter is an essential tool for getting the job done
Reliable sources of water are essential in a fire emergency. Hydrant pressure tests ensure this reliability by determining the pressure and rate of flow at any point in a water distribution system. This is accomplished by measuring static (non-flowing) and residual (flowing) pressure, as well the rate of discharge in liter per minute (LPM) of each fire hydrant
Methodology
- Shut off the complete hydrant system and measure the head of the pump.
- Adjust the head of the pump by the existing valve of the hydrant, measure the flow of water by opening the hydrant accordingly.
- Hydrant to be opened to be delivered 125% of the flow.
- Check the rpm of the pump at each operating point.
