Instead of disassembling your system for inline installation, thread these flow switches onto a mounting adapter (sold separately) and insert them into a pipe tee or pipe outlet. They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures. Use the buttons on the display to adjust the set point and other settings. These switches are accurate in any mounting position.

IP65 rated switches protect against dust and washdowns. IP67 rated switches withstand temporary submersion.

When these switches reach a set flow rate, they send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms. Use the adjustment screw to select their set point. 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. They must be mounted horizontally to function correctly. IP rated, they withstand dust, washdowns, and temporary submersion.

These switches are calibrated with and measure water accurately. They can also be used with other liquids by applying your liquid’s specific-gravity conversion factor to calculate the new set point.

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.

Easy to clean and install, these flow switches are 3-A certified to meet sanitary design standards and insert into your line with a quick-clamp mounting adapter (sold separately). They have a smooth probe, and unlike flow switches that measure with a paddle or turbine, these don’t have moving parts for contaminants to get stuck in. Rated IP67 and IP69K, they withstand temporary submersion and high-temperature, high-pressure washdowns. The mounting adapter attaches to a quick-clamp tube tee or outlet (often called tri-clamp fittings) in your large-diameter tubing system using a gasket and clamp (not included), so you don't need to disassemble your line for inline installation. This mounting adapter is also easy to remove and clean.
