A new series of solid state waterflow detectors is now available from System Sensor. The Accuflow series includes models for 2" through 8" steel pipe risers, as well as 1" NPT branch line applications. The detectors are compatible with a range of pipe schedules, including 2" schedule 5-40, 2"-6" schedule 7-40, and 8" schedule 10-40. The Accuflow detector's retard mechanism ensures consistent timing accuracy to within one second. Dipswitch selections permit field adjustment of retard settings. The detectors' non-polarized, two-wire design allows connection to both conventional and addressable fire and/or security systems, as well as a local bell or notification device. www.systemsensor.comSystem Sensor.
