Send flow rate measurements to monitor and control equipment. Also known as transducers, these transmitters convert flow rate measurements to an electrical signal that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs). As flow 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 flow correctly no matter their 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.

Variable Area Flow Measurement—Variable-area transmitters determine flow rate by tracking where the liquid pushes an internal piston.

Turbine Flow Measurement—Turbine transmitters measure flow by counting how many times their turbine turns as liquid passes through. To avoid clogging the turbine and other damage, use them only with clean, low-viscosity liquids. The digital output sends flow data with a pulse, which is a spike of voltage. The higher the flow, the more pulses they send. The voltage of the pulse output matches the input voltage sent to the transmitters. These transmitters meet NSF/ANSI 61 for use with drinking 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.

Variable Area Flow Measurement—Variable-area transmitters determine the flow rate by tracking where the liquid pushes the piston. They have two configurable outputs. One can be wired as an analog output or a digital switch. The other one can be wired as a digital switch, digital pulse output, or IO Link. Pulse outputs send flow data using spikes of voltage that match the input voltage of the transmitter. The higher the flow, the more pulses they send. These transmitters are calibrated with water, glycol solutions, and coolants but can be recalibrated in the field for other liquids.

Vortex Flow Measurement—Vortex transmitters determine the flow rate by measuring the size of the vortex created as liquid flows through them. They don’t have any moving parts that can break or get stuck. Use them only with liquids that are at least 95% water. They have one analog output for flow and another for temperature. The output for temperature can also be wired for IO Link.

Using ultrasonic waves, these transmitters measure the flow rate of your liquid from outside your pipe. They're a good choice for applications where you need to retrofit your system or avoid liquid coming into contact with the transmitter. Also known as transducers, these transmitters convert measurements to an electrical pulse that can be interpreted by receiving devices, such as remote displays and programmable logic controllers (PLCs). The pulse outputs match the input voltage of the transmitter. The higher the flow, the more pulses they send. 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. Configure them for either a 4-20mA or digital pulse output when installing.

A digital display makes it easy to check flow rate and configure settings. Clamp these transmitters onto your pipe with the included mounting hardware and gel pads. They measure flow no matter the mounting orientation.

These transmitters are calibrated with water but can be used with other liquids and will generally measure accurately, even if they differ in viscosity and density. You can recalibrate them in the field for accurate readings on pipe and operating conditions.

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). To measure flow, they have oval-shaped gears that move the liquid through the flowmeter—how fast the gears turn correspond to the flow rate. Also known as transducers, they help you monitor status or control equipment by converting measurements to an electrical pulse that can be interpreted by receiving devices. The higher the flow, the more pulses they send. Mount them inline with your pipe system. They’re accurate in any mounting orientation.

These transmitters are calibrated with oil but can be used with other liquids and will generally measure accurately, even if they differ in viscosity and density.

Thread mounting hardware (sold separately) into your pipe connection and insert the probe of these transmitters to measure the flow and temperature of water, oil, or air. The probe is held in place with a compression fitting on the other end of the mounting hardware. They’re often used in large-diameter pipes where it would be difficult to install a transmitter inline. To calculate the flow rate, these transmitters generate a small amount of heat, then measure the cooling effect your liquid or air has on it. They measure and output both flow and temperature, making them ideal for applications where temperature fluctuates. Also known as transducers, they 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. 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. They’ll measure flow correctly in any mounting orientation. These transmitters are calibrated with air, glycol solutions, oil, and water but can be recalibrated in the field for other liquids.

Adjust settings at the source using the digital display. These transmitters have two configurable outputs. One can be wired for flow or temperature as an analog output or a digital switch. The other one can be wired for flow as a digital switch, digital pulse output, or IO Link. Pulse outputs send flow data using spikes of voltage that match the input voltage of the transmitter. The higher the flow, the more pulses they send. To change settings and receive error messages remotely from your PLC or computer, you can program one of the outputs to use IO Link. You’ll need an IO Link controller (not included) to connect to your interface.

Commonly referred to as thermal mass flowmeters, these transmitters calculate flow rate by measuring how much they cool as air and other gases pass through them. This means they’re accurate even if there are temperature and pressure changes, unlike most other transmitters. Used to monitor flow or control equipment, these transmitters, also known as transducers, convert measurements to an electrical signal that is interpreted by receiving devices. As flow 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. A digital display makes it easy to check the flow rate and adjust settings. Mount these transmitters inline with your system.

These transmitters are calibrated with air. You can use them with other gases, but they will not be as accurate.
