Covers the design and performance requirements for 1 inch through 8 inch nominal size water flow detector testers. Includes both traditional mechanical type water flow detector testers (where the water flow detectors are tested by the passage of water past the vane), and electrical style (where the water flow past the water flow detector is electrically simulated). Also verifies that the product described will meet stated conditions of performance, safety and quality useful to the ends of property conservation.
