About Flowmeters and Totalizers
Flowmeters measure the rate of flow for a liquid or a gas. Totalizers measure the cumulative flow volume. Flowmeter/totalizers display both the flow rate and the cumulative flow volume.

Easy-Read Flowmeters
A large dial instead of a scale makes it easier to read the flow rate from a distance. As liquid flows through these flowmeters, it pushes a needle along the dial, showing you the flow rate. They measure flow correctly no matter the mounting orientation.
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.
Choose a direction of flow that matches your pipe system, so you don't have to tilt your head to read the dial.
Style B flowmeters should be installed away from other fittings to get the most accurate reading. To determine how far away from the fittings it should be, take your pipe's diameter and multiply it by 10.
Choose a fitting material that is compatible with the liquid you're running through your line. Aluminum, brass, bronze, and 316 stainless steel fittings resist impact better than PVC fittings.

Any-Orientation Flowmeters
A spring piston instead of a float allows these flowmeters to measure flow rate in any mounting orientation. As liquid passes through, it pushes an indicator up the scale, showing you the flow rate. They have union fittings on both ends, making it easy to position the scale so it’s visible.
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.
Choose a fitting material that is compatible with the liquid you intend to run through your line. Brass fittings resist impact better than polysulfone fittings.

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.

Easy-Read Flowmeters for Gases
Instead of a scale, these flowmeters have a large dial that makes it easy to read the flow rate of your gas from a distance. As gas flows through, it pushes a needle along the dial, showing you the flow rate.
These flowmeters are calibrated with air but can be used with other gases. If you’re using these with a gas other than air, you’ll need to calculate the flow rate by multiplying the number shown on the scale by the specific-gravity conversion factor for your gas.
Flowmeters with a bronze body should be installed away from other fittings to get the most accurate reading. To determine how far away from the fittings it should be, take your pipe's diameter and multiply it by 10.

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. A complete transmitter consists of a flow transmitter, display, and mounting hardware kit (all components sold separately). Flowing liquid turns the turbine in the transmitter, while the easy-to-read display counts the number of turns to measure and transmit the flow. The display also shows total and batch flow volumes. Use these transmitters with clean, low-viscosity liquids to avoid clogging or other damage to the internal parts. Mount them inline with your pipe system. They’re accurate in any mounting orientation.
Also known as transducers, these transmitters help you monitor status or control equipment by converting measurements to a digital pulse that can be interpreted by receiving devices. Each pulse is a spike of voltage. The higher the flow, the more pulses they send. 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. Transmitters will only provide accurate readings within the rated measurement range.
The transmitters are calibrated with water but can be used with other liquids.

Socket-Connect Flowmeter/Totalizers
The unthreaded ends of these flowmeter/totalizers install into a PVC piping system, so you can measure the flow rate and volume of liquid passing through your system. Bond the joint together with PVC cement and primer. You can reset the batch total, but you can't reset the cumulative total. They measure flow correctly no matter the mounting orientation.
These flowmeter/totalizers are calibrated with water.
Ultrasonic flowmeter/totalizers measure flow with ultrasonic waves, so they don’t have internal moving parts that can break or get stuck.
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.

Socket-Connect Flowmeter/Totalizers with Remote Display
Often used in hard-to-access areas, these flowmeter/totalizers have a display that can be placed up to 25 feet from the sensor. Use them to measure the rate and volume of liquid flowing through your system. They measure flow 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. Batch totals are resettable but can be protected with a security code to prevent tampering. The reset function can also be disabled so that they operate as a cumulative totalizer. Cumulative totals cannot be reset. No matter the mounting orientation, they’ll measure flow correctly.
These flowmeter/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.
For a complete unit, you’ll need a display, a sensor, and a tee fitting (all sold separately).
Tee fittings mount inline with your pipe. They have two unthreaded socket ends that bond to unthreaded PVC pipe with PVC cement and primer.

Flanged Totalizers for Drinking Water
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 Flow Switches
Connection
with IP65 Rating
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.
Switches with a Noryl plastic body have a paddle that you trim to adjust the set point. The more you trim, the higher the set point.
Choose a fitting material that is compatible with the liquid you're running through your line. Noryl plastic fittings work with a wide range of chemicals. Brass and 316 stainless steel fittings resist impact better than Noryl plastic fittings.
Socket-connect flow switches bond to an unthreaded PVC pipe tee or pipe outlet with PVC cement and primer (not included).
IP65 rated switches seal out dust and can be lightly rinsed.
