For monitoring flow at a glance, these switches have a plastic window with a rotor indicator that spins when there’s flow. They activate or deactivate equipment when the flow rate reaches your set point. Tighten or loosen the adjustment screw to choose your set point anywhere within the range. To measure flow, they count how many times the turbine turns as liquid flows through. Use them only with clean, low-viscosity liquids to prevent clogging the turbine and other damage. All are single pole, double throw (SPDT) and can either turn one device from off to on (normally open) or on to off (normally closed).

These switches are calibrated with water. They can also be used with other liquids but may not measure accurately if their viscosity is significantly different.

Choose a fitting material that is compatible with the liquid you're running through your line.

Send flow rate data using these transmitters while also being able to visually confirm liquid is flowing. They measure flow by counting how many times the turbine turns as the liquid moves through it. To prevent clogging the turbine and other damage, use them only with clean, low-viscosity liquids. These transmitters, also known as transducers, convert the flow measurement to an electrical signal that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs), to monitor flow or control equipment. Mount them directly inline with your system. They measure accurately in any mounting orientation.

These transmitters are calibrated with water. You can use them with other liquids, but they may not measure accurately if the liquid’s viscosity differs from water.

Send flow rate and temperature measurements simultaneously to a programmable logic controller (PLC), data logger, or other receiving device. Used to monitor status or control equipment, these transmitters, also known as transducers, convert measurements to an electrical signal that is interpreted by receiving devices. As flow or temperature increases, the output signal increases. For your receiving device to interpret the signal, you will need to calibrate it for the measurement range and output signal of the transmitter. They only give accurate readings within the rated measurement range. Mount them inline with your pipe system. They’ll measure flow correctly in any mounting orientation.

A digital display makes it easy to view readings and adjust settings at the source. To change settings and receive error messages remotely from your PLC or computer, program one of the outputs to use IO Link. You’ll need an IO Link controller (not included) to connect to your interface.

Also known as magmeters, these transmitters use a magnetic field to measure flow rate and temperature with high accuracy. Because they use a magnetic field, they only work with conductive liquids, such as water. These transmitters, also known as transducers, convert measurements to an electrical signal that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs) to monitor flow or control equipment. For your receiving device to interpret the signal, you will need to calibrate it for the measurement range and output signal of the transmitter. As flow or temperature increases, the output signal increases. These transmitters have one analog output for flow and another for temperature. They only give accurate readings within the rated measurement range. A digital display makes it easy to view readings and adjust settings at the source. Mount these transmitters inline with your pipe system. They measure flow correctly in any mounting orientation.

These transmitters are calibrated with water. They can only be used with liquids with a conductivity of at least 20 µS/cm.

Measure and transmit flow rate, pressure, and temperature of industrial gases, such as air, argon, CO2, and nitrogen, flowing through your system. These transmitters are ideal for applications where temperature and pressure can fluctuate. To calculate flow rate, they generate a small amount of heat, then measure the cooling effect your gas has on it. Also known as transducers, these transmitters convert measurements to an electrical signal that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs). As flow, temperature, and pressure increases, the output signal increases. For your receiving device to interpret the signal, you will need to calibrate it for the measurement range and output signal of the transmitter. They only give accurate readings within the rated measurement range. Mount them directly inline with your system. They measure correctly no matter their mounting orientation.

A digital display makes it easy to read measurements and adjust settings based on your gas. These transmitters have two configurable outputs, and each output can only be wired for one measurement (flow rate, pressure, or temperature). Outputs configured as digital pulse send flow data using spikes of voltage that match the input voltage of the transmitter. One of the outputs can be wired for IO-Link, so you can change settings and receive error messages remotely from your PLC or computer. You’ll need an IO Link controller (not included) to connect to your interface.

These transmitters are calibrated with air but still measure accurately when used with other gases.
