What device measures water flow in sprinkler systems?

• A. Water meters
• B. Pressure-reducing valves
• C. Maximum working pressure
• D. Light hazard occupancy

Answer: (A)

Water meters measure the amount of water moving through the service line into the sprinkler system, providing a record of flow (volume over time) for testing, verification of supply, and billing. They are the device placed on the water supply path to quantify how much water is delivered to the system. The other options don’t measure flow: a pressure-reducing valve lowers pressure, maximum working pressure is a rating, and light hazard occupancy is an occupancy classification.
