Contactless Flow Transmitters
 |
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.

Portable Noncontact Flowmeters
 |  |
Often used to pinpoint flow issues, these flowmeters clamp onto pipe, so you can spot-check the flow rate at different points without disassembling your system. They measure by tracking the time it takes for ultrasonic waves to pass through your liquid, so they don’t need to come into contact with your liquid. As a result, they can be used with a wider range of liquids than other flowmeters.

Flanged Totalizers for Drinking Water
 |  |
Bronze Body Round Flange | Bronze Body Analog Display |
Flanged ends let you securely integrate these totalizers into large drinking water pipelines to measure the cumulative amount of water flowing through them. They meet NSF/ANSI 61, so they're safe to use with drinking water. They measure flow volume by counting how many times their turbine turns as liquid flows through. To avoid clogging the turbine and other damage to the sensor, use them only with clean, low-viscosity liquids. Their total cannot be reset.
These totalizers 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.

Insertion Flowmeters
 |
No need to disassemble your PVC pipeline—insert these flowmeters into a drilled hole and secure them using the included clamps. As liquid flows through the meter, it pushes an indicator up the scale, showing you the flow rate. They have a clear body, so you can check the color and clarity of flowing liquid to identify and diagnose problems. Mount these flowmeters vertically.
These flowmeters are calibrated with water but can be used with other liquids. If you’re using these with a liquid other than water, you’ll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for your liquid.

Output modules allow you to transmit flow data from flowmeter/totalizers to an external device such as a programmable logic controller (PLC), data recorder, logger, and remote display.
4-20 mA output modules have an analog output. As flow increases, the output signal from the transmitter increases. For your receiving device to interpret the signal from the transmitter, 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.
Pulse output modules have a digital output. They transmit flow data using spikes of voltage that match the input voltage of the transmitter. The higher the flow, the more pulses they send.

Insertion-Mount Flow Switches
 |  |  |
Threaded Connection with IP65 Rating | Threaded Connection with NEMA 4X Rating | Threaded Connection |
Avoid complicated inline installation—these flow switches insert into a tee or pipe outlet, so you don’t need to disassemble your pipeline. They have a paddle that’s pushed as your liquid moves through to determine flow. When the paddle reaches a set position determined by the set point, it activates or deactivates equipment. They are single pole, double throw (SPDT) and can either turn one device from off to on (normally open) or on to off (normally closed). They should be mounted vertically into a large-diameter horizontal pipeline, so liquid pushes the paddle.
These flow switches 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.
Choose a fitting material that is compatible with the liquid you're running through your line.
316 Stainless Steel Body and Brass Body—Switches with a brass or 316 stainless steel body have multiple paddles you can choose between to get you closest to your set point. For a higher set point, loosen the locking washers to remove the largest paddles. You can also trim the paddles to fine-tune your set point. The more you trim, the higher the set point.
Noryl Body—Switches with a Noryl body have a paddle that you trim to adjust the set point. The more you trim, the higher the set point.
316 Stainless Steel Fitting and Brass Fitting—Brass and 316 stainless steel fittings resist impact better than Noryl fittings.
IP65 Enclosure Rating—IP65 rated switches seal out dust and can be lightly rinsed.
NEMA 4X Enclosure Rating—NEMA 4X rated switches protect against dust, weather, and washdowns.

Hazardous-Location Insertion-Mount Flow Switches
 |
Safely activate and deactivate equipment in environments with flammable gases and combustible dust when your flow rate reaches a set point. They are UL listed and CSA certified for use in hazardous locations. These switches save you from disassembling your pipeline because you insert them into pipe tees or pipe outlets instead of mounting them inline. They actuate when your system’s liquid pushes the paddle into a set position. To change your set point, the paddle has multiple layers that you can remove. For the lowest set point, use the largest paddle that will fit your pipe. To increase your set point, loosen the locking washers and remove paddles. You can trim the paddles to fine-tune your set point. The smaller the paddle, the higher the setpoint.
They should be mounted vertically into a horizontal pipeline, so liquid pushes the paddle.
These switches are calibrated with water and air. They can also be used with other liquids and gases but may not measure accurately if their viscosity is significantly different.
SPDT—SPDT (singe pole, double throw) switches can turn one device from off to on (normally open) or from on to off (normally closed).
DPDT—DPDT (double pole, double throw) switches can either turn two devices from off to on (normally open) or on to off (normally closed).
