Product Information
Water flow detectors are mounted to water-filled pipes in sprinkler systems. It is used on steel pipe, schedules 10 through 40, sizes 50mm - 200mm(2” thru 8”). Water flow in the pipe deflects a vane, which triggers a switch usually after a specified delay period. All water flow detectors have a pneumatically controlled mechanical delay mechanism. Delays reset if the flow of water stops before the entire delay has elapsed. All switches actuate when the water flow rate is 10 gallons per minute or greater, but will not actuate if the rate is less than 4 gallons per minute.
The cover incorporates tamper resistant fasteners that requires a special key for removal. One key is supplied with each device.
