High-Pressure Flow Switches for Oil
 |
Measure the flow rate of oil at pressures up to 3,600 psi to activate or deactivate equipment. Designed to compensate for viscosity and density changes, these switches have an adjustment screw to select your specific flow rate within the set point range. As flowing liquid pushes an internal piston, the switch reads the position of the piston to measure the flow. When the piston passes the set point, the switch actuates. These switches are single pole, double throw (SPDT) and can turn one device from off to on (normally open) or from on to off (normally closed). Their IP65 rating protects them from dust and low-pressure washdowns, such as from a garden hose. All are accurate in any mounting position.
These switches are calibrated with and measure oil accurately. They can also be used with other liquids by applying your liquid’s specific-gravity conversion factor to calculate the new set point.

High-Pressure Flow Switches for Gas
 |
Good for compressed-air systems and other compressed gases that reach up to 3,600 psi, these switches measure the flow rate to activate or deactivate equipment when they reach a set point. Tighten or loosen the adjustment screw to choose your flow rate anywhere within the set point range. As flowing gas pushes an internal piston, the switch reads the position of the piston to measure the flow. When the piston passes the set point, the switch actuates. These switches are single pole, double throw (SPDT) and can turn one device from off to on (normally open) or from on to off (normally closed). They must be mounted horizontally to function correctly. IP rated, they seal out dust and can be lightly rinsed.
These switches are calibrated with and measure air accurately. They can also be used with other gases by applying your gases’ specific-gravity conversion factor to calculate the new set point.
