An adjustment screw lets you alter the set point to suit your application. These switches activate or deactivate equipment when the flow rate reaches your set point. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).

These switches activate or deactivate equipment when the flow rate reaches your set point. They are single pole, double throw (SPDT) and can be installed to turn one circuit 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 bronze body.

For protection from dirt, washdowns, and corrosion, these switches have an enclosure that meets NEMA 4X. They activate or deactivate equipment when the flow rate reaches your set point and have an adjustment screw for altering the set point. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).

These switches are UL listed and CSA certified for environments with flammable gases and combustible dust. They activate or deactivate equipment when the flow rate reaches your set point. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).

Switches with a brass body meet NEC Class I, Divisions 1 and 2, Groups B, C, and D; and NEC Class II, Divisions 1 and 2, Groups E, F, and G.

Switches with a 304 stainless steel body are more corrosion resistant than switches with a brass body and meet NEC Class I, Divisions 1 and 2, Groups A, B, C, and D; and NEC Class II, Divisions 1 and 2, Groups E, F, and G.

For applications with a variable flow rate in environments with flammable gases and combustible dust, these UL-listed switches have an adjustment screw to alter the set point. They activate or deactivate equipment when the flow rate reaches your set point. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).

Switch with a brass body meets NEC Class I, Divisions 1 and 2, Groups B, C, and D; and NEC Class II, Divisions 1 and 2, Groups E, F, and G.

Switch with a 304 stainless steel body is more corrosion resistant than the switch with a brass body. It meets NEC Class I, Divisions 1 and 2, Groups A, B, C, and D; and NEC Class II, Divisions 1 and 2, Groups E, F, and G.

For flow monitoring at a glance, these switches have a plastic window with a rotor indicator that spins when flow is present. They activate or deactivate equipment when the flow rate reaches your set point. All have an adjustment screw for altering the set point to suit your application. Switches are single pole, double throw (SPDT) and can be installed to turn one circuit from "off" to "on" (normally open) or from "on" to "off" (normally closed).

Switches with a polypropylene body are lighter than sights with a metal body.

Switches with a 316 stainless steel body are more corrosion resistant than switches with a brass body.

Install these switches 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) or from “on” to “off” (normally closed). They come with four 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.

Switch with a 316 stainless steel body is more corrosion resistant than switches with a brass body.

Switch with an enclosure that meets NEMA 4X provides protection from dirt, washdowns, and corrosive liquids.

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 paddle can be trimmed to fit a range of pipe sizes. The flow rate varies based on the pipe size and the paddle length. Enclosure meets NEMA 4X for protection from dirt, washdowns, and corrosive liquids.

Socket-weld connection is for use with unthreaded male pipe.

Threaded connection is for use with NPT female pipe.

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).
