Compact Insertion Flow Switches for Water
At half the height of standard insertion flow switches, these are often installed in tees or pipe outlets in low-clearance areas. They’re installed in tees or pipe outlets to detect the flow rate of liquid in contact with the sensing paddle. They activate or deactivate equipment when the flow rate reaches your set point. Switches are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open). The flow rate varies based on the pipe size and the paddle length.
Maximum flow rate is how much water can temporarily flow through your pipe without damaging the switch.
Switches with a socket-weld connection are for use with unthreaded male pipe. Those with a threaded connection are for use with NPT female pipe.
Switches with a trimmable paddle can be cut to fit a range of pipe sizes. Those with a 301 stainless steel paddle can be used with higher maximum flow rates than switches with a Noryl plastic paddle.

Hazardous Location Insertion Flow Switches for Water, Oil, Air, and Inert Gas
For installation in environments with flammable gases and combustible dust, these flow switches are UL listed for hazardous locations. They meet NEC Class I, Divisions 1 and 2, Groups C and D; and NEC Class II, Divisions 1 and 2, Groups E, F, and G. They’re installed in tees or pipe outlets to detect the flow rate of liquid in contact with the sensing paddle. Switches activate or deactivate equipment when the flow rate reaches your set point. All come with five sensing paddles that can be trimmed to fit a range of pipe sizes. The flow rate varies based on the pipe size and paddle used.
SPDT switches control one circuit. They can be installed to turn the circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).
DPDT switches control two circuits. They can be installed to turn both circuits from “off” to “on” (normally open) or from “on” to “off” (normally closed).
Switches with a 316 stainless steel body are more corrosion resistant than switches with a brass body.
