Air and Liquid Flow Switches

▪Single-pole, double-throw snap switch ▪Sensitivity flow adjustment screw ▪120/240VAC operation ▪Full load amps: 7.4 at 115V, 3.7 at 230V Additional flow range information is available on Grainger.ca.

Liquid Flow General-Purpose—Start or stop electrically operated equipment such as signal lights, alarms, motors, automatic burners, and metering devices. Nos. WWG2RUL3 and WWG2RUL4 have 4 stainless steel paddles that fit 1", 2", 3", and 6" pipe; paddle can be trimmed to fit incremental pipe sizes.

Liquid Flow High-Sensitivity—For heavy-duty applications that need instant switching such as water treatment systems, electronic circuit cooling systems, compressors, booster pumps, and bearings.

Liquid Flow Industrial/Heavy-Duty—Designed for large pipe applications, including heating and hydronic systems, air conditioning, refrigeration, and process work. Paddles can be trimmed to suit. Fit 2" to 16" pipe with flow rates up to 998 gpm.

Paddle Kits—Designed to replace damaged paddles and return flow switches to original flow-sensing capability. WWG2RUL4 WWG2RUL3

Paddle Liquid Flow Switches These GEMS SENSOR liquid flow switches can sense liquid flow in either direction to monitor flow/ no-flow conditions. The paddle style is trimmed during installation to allow switch actuation at the desired flow rate. As pipe flow increases, the switch paddle pivots to move out of the liquid path, producing less than 3 psig pressure drop no matter the pipe size. WWG1AKZ4

GEMS SENSORS

Liquid Mechanical Flowmeters Thes epositive displacement, nutating disc flowmeters are ideal for in-line use, or can be mounted to a Fill-Rite® diaphragm or rotary vane pump. The corrosion-resistant housing is rugged enough for most applications. Model allows for simple selection of metering units and is easy to calibrate.
