What type of device is utilized to test the flow rates of water in fire protection systems?

The device that is specifically utilized to test the flow rates of water in fire protection systems is the Pitot Gauge. This tool measures fluid flow velocity and is commonly used in conjunction with a flow meter to assess how much water is being delivered through a fire protection system.

The Pitot Gauge operates by measuring the dynamic pressure of the water as it flows through a pipe. It calculates the velocity of water based on this pressure differential, enabling technicians to determine the flow rate effectively. This is crucial in fire protection systems to ensure that they can deliver adequate water supply during a fire incident.

While flow meters can also measure the flow rate, they typically provide a continuous readout of water flow and are more often used for monitoring rather than field testing. Pressure gauges measure the pressure within the system, and vacuum gauges measure negative pressure, neither of which directly yields flow rate information. Thus, using a Pitot Gauge is the most appropriate choice for specifically testing flow rates in fire protection systems.
