McDonnell & Miller Flow Switches Are Used For General Purpose Air And Liquid Flow Applications.
McDonnell & Miller Flow Switches are solidly manufactured for long lasting durability and dependability. Series AF1 Air Flow Switch is for applications with medium and high velocity requirements. Brass, steel and aluminum construction. Single pole, double throw snap switch. Sensitivity adjusting screw makes flow adjustment easy. Two electrical knock-outs allow connection from either end. Can be equipped with a time delay relay. Series FS1 High Sensitivity Liquid Flow Switch is for applications where high sensitivity is required and moderate or low flow rates are encountered such as air conditioning, heating and hydronic systems, water, fuel oil, some viscous liquids and oils in process work. In-line configuration eliminates need for a pipe tee. Switch compartment is completely sealed to protect it from the liquid. Series FS7-4 Industrial Liquid Flow Switch is used for large pipe applications, including heating and hydronic systems, air conditioning, refrigeration and process work. Brass with sealed tube construction. Single pole, double throw snap switch. Magnetic switching mechanism eliminates need for bellows. Series FS8-W Liquid Flow Switch With Gold Plated Contacts is for applications with environmental exposure or those requiring a water-tight, dust tight or a NEMA 4X rated flow switch. Sealed Monel bellows. Single pole, double throw snap switch. Four stainless steel paddles included.
