The new Series AVFS Adjustable Air Flow Switch complements the Dwyer Instruments line of thermo-anemometer transmitters and handheld instruments. The AVFS is specifically designed to monitor air flow in ducts and provides a 3A contact output to indicate a change or loss of flow. Simply turn on the fan or air handling unit and adjust the set-point via the potentiometer to show normal status. Then alter a damper or decrease fan speed to activate the AVFS. The AVFS will signal a loss of flow and the N.O. SPST output will indicate the detected decrease. For ease of installation and system troubleshooting, the Series AVFS possesses a redgreen LED indication to provide local status if the air flow is above (green) or below (red) the set-point. The AVFS provides a ±5% set-point repeatability across a full scale range of 1-10 ms (197-1969 fpm) and includes a mounting bracket for quick duct mounting. The AVFS Series Adjustable Air Flow Switches come in a compact, rugged PBT enclosure that is rated NEMA 4X (IP65), making them ideal for any ventilation system installation or similar BAS application.

SIGMA's Flow Switch is an extension of the level switches. There are two types of flow switches : one for low flow / line size up to 50 mm line size (Model FS 1000) and another from 25 mm onwards up to 800 mm or above (Model FS 1010).Operating Principle :Model FS 1000 is a valve type Flow Switch wherein an increase in flow through the body raises the valve disc depending upon the flow. This in turn raises the magnetic sleeve moving inside a non-magnetic enclosure. The movement of the sleeve attracts the magnet located outside the tube which in turn actuates a micro switch. Decrease in flow reverses the action.Model FS 1010 is a target type which moves from a vertical position to a near horizontal position as the flow increases. This change in position moves a magnetic sleeve in a non-magnetic enclosure. The movement of the magnetic sleeve attracts a magnet which in turn actuates a micro switch. Decrease in flow brings the target back to the vertical position.
