Inline Flow Switches

Fixed-Setpoint Flow Switches

Since they come factory set to a specific set point, these switches are easier to install than adjustable flow switches.

Flow Switches with Sight

For monitoring flow at a glance, these switches have a plastic window with a rotor indicator that spins when there’s flow.

Fixed-Setpoint Flow Switches for Drinking Water

Factory set to activate equipment when your drinking water system reaches a fixed level, these flow switches are easier to install than adjustable flow switches.

Flow Switches

Activate or deactivate equipment when your flow rate reaches a set point.

Variable-Pressure Flow Switches

Accurate even in applications where pressure fluctuates regularly, these flow switches split flow into two paths and measure their difference in pressure drop to calculate the flow rate of liquid.

Fixed-Setpoint Hazardous Location Flow Switches

Safe to use where flammable gases and combustible dust may be present, these switches activate or deactivate when your flow reaches a factory-set level. All are UL listed for hazardous environments.

Hazardous Location Flow Switches

UL listed for use where flammable gases or combustible dusts may be present, these flow switches activate or deactivate equipment when your flow rate reaches a set point.

Fixed-Setpoint High-Pressure Flow Switches

Quicker to install than adjustable flow switches in high-pressure lines, these switches come factory-set to activate or deactivate equipment at a specific level. They compensate for the viscosity and density changes of liquid.

High-Pressure Flow Switches for Oil

Measure the flow rate of oil at pressures up to 3,600 psi to activate or deactivate equipment.

High-Pressure Flow Switches

Rated for pressures up to 3,600 psi, these switches measure the flow rate of liquids to activate or deactivate equipment when your flow rate reaches a set point.

Electronic Flow Switches

When these switches reach a set flow rate, they send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms.

Insertion Flow Switches

Avoid complicated inline installation—these flow switches insert into a tee or pipe outlet, so you don’t need to disassemble your pipeline.

Fixed-Setpoint Insertion Flow Switches

Easy to install, these flow switches come already set to a specific set point and don’t require you to disassemble your pipeline.

Electronic Insertion Flow Switches

Instead of disassembling your system for inline installation, thread these flow switches onto a mounting adapter 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.

Sanitary Electronic Insertion Flow Switches

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. They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate.

Hazardous Location Insertion Flow Switches

Safely activate and deactivate equipment in environments with flammable gases and combustible dust when your flow rate reaches a set point. These switches save you from disassembling your pipeline because you insert them into pipe tees or pipe outlets instead of mounting them inline.

Flow Transmitters

Noncontact Flow Transmitters

Using ultrasonic waves, these transmitters measure the flow rate of your liquid from outside your pipe.

Flow Transmitters with Sight

Send flow rate data using these transmitters while also being able to visually confirm liquid is flowing.

Flow Transmitters

Send flow rate measurements to monitor and control equipment.

Flow and Temperature Transmitters

Send flow rate and temperature measurements simultaneously to a programmable logic controller (PLC), data logger, or other receiving device.

High-Accuracy Flow and Temperature Transmitters

Also known as magmeters, these transmitters use a magnetic field to measure flow rate and temperature with high accuracy.

Insertion Flow and Temperature Transmitters

Thread a ring fitting into your pipe connection and insert the probe of these transmitters to measure the flow and temperature of water, oil, or air.

Ultra-Low-Flow Flow Transmitters

Often used in low-flow metering applications for lubricants or antifreeze, these transmitters measure flow rate and send the data to a remote display or programmable logic controller (PLC).

Flow Transmitters for Flanged Pipe

Install these transmitters between two flanges in a flanged pipe system to measure flow rate and send the data to a remote display or programmable logic controller (PLC). For easy cleaning and maintenance, you can slide the transmitter out from between the flanges.
