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 trouble-shooting, the Series AVFS possesses a red/green LED indication to provide local status if the air flow is above (green) or below (red) the set-point. 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.
Mounting:
Mount the airflow monitor by means of the mounting clamp provided. Diameter of the mounting hole for the unit: .9 in (24 mm) mm. If mounting is to be airtight, use the gasket provided. The sensing head must be completely immersed into the airflow and should be in the range of the highest flow velocity, if possible.
Maintenance:
Upon final installation of the Series AVFS Air Flow Switch, no routine maintenance is required. The Series AVFS is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return goods authorization number before shipping.
