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.

Flanged Flowmeters
Install these flowmeters securely into large pipelines with the flanged ends. They have a case that protects them from blows that could crack or shatter the body. Mount them vertically inline with your pipe system, so liquid flows up from the bottom. As liquid flows through the meter, it pushes an indicator up the scale, showing you the flow rate.
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.

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.

Flanged Flowmeter/Totalizers
Using the flanged ends, securely install these flowmeter/totalizers in large, high-flow pipelines to measure the flow rate and total volume of liquid flowing through. They use ultrasonic waves to measure flow, so they don’t have any internal moving parts that can break or get stuck. You can reset the batch total, but you can't reset the cumulative total. They measure accurately in any mounting orientation.
These flowmeter/totalizers are calibrated with water.

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.
Optional elliptical flange kit lets you convert elliptical flanges to NPT female connections.

High-Vacuum Flanged Sights
Add a window to your high-vacuum system. With a pane of glass sealed inside a high-vacuum CF flange, these sights bolt onto vacuum chambers, tee fittings, and manifolds. Use a copper gasket (sold separately) to create a seal. Not for use with pressure. To illuminate dark interiors, attach an optional light to the flange with set screws.
