ORI - Model 30000 Series -Flow Switch Piston Sensor for Liquids

Orange Research manufactures these flow switches with a compact size and basic profile, resulting in a low-cost switch that can be mounted where space is limited. This makes these flow switches popular for OEM applications where simple flow switch actuation is required.

As a leading flow switch manufacturer, we produce these components with rugged materials to allow for long-term, high-pressure use. Orange Research flow switches are popular for portable systems where shock and vibration are common. Stainless steel springs and brass or stainless steel pistons and pressure bodies allow these flow switches to be used in a variety of applications, including lubricating systems, chillers, coolers and heat exchangers.

Flow Switch Calibration

Flow switches are calibrated on increasing flow in the vertical position on water at 70°F. For other fluids or conditions we can manufacture your flow switch with special calibration and settings, as requested. In this case, specify orientation, fluid, specific gravity and viscosity.

How a Flow Switch Works

Designed for in-line use, the fluid enters the end connection and exits the flow switch side port. As the fluid passes through the flow switch it pushes against a spring-loaded piston magnet sensor. As the sensor magnet moves into proximity of the reed switch, the switch is activated.
