System Sensor’s Accuflow
™
Low Flow Rate detectors are a new line of solid state
waterflow detectors designed for use in wet pipe water mist systems where low
flow detection is required.
Robust Construction.
Accuflow low flow detectors consist of a rugged enclosure for
indoor and outdoor use. Like all System Sensor waterflow detectors, low flow models
operate across a wide temperature range, from 32ºF to 120ºF (0°C to 49°C).
Reliable Performance.
Accuflow low flow detectors are intended for applications
where flow detection of 3 GPM or greater is required. By incorporating a solid state
retard, proper sensitivity, timing accuracy and switch resetting is assured.
False Alarm Immunity.
The solid state circuitry of Accuflow low flow detectors
provides greater timing accuracy over traditional mechanical retard designs. This
accuracy minimizes the risk of false alarms created by pressure surges or air trapped
within the sprinkler system.
Simplified Operation.
Accuflow low flow detectors are designed to simplify installa-
tion. Wired like traditional waterflow detectors, these models do not require the
installer to run an additional third wire. Two conduit openings permit easy attach-
ment to the local alarm system.
