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.
