System Sensor’s Accuflow

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.
