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.

Flowmeter/Totalizers for Water

Determine the flow rate and total flow volume of water with the same meter.

Washdown Flowmeter/Totalizers for Water

To protect against dust, washdowns, and corrosion, these flowmeter/totalizers have an enclosure that meets NEMA 4X.

Remote-Reading Socket-Connect
Flowmeter/Totalizers for Water

With a display that can be placed up to 25 feet from the sensor, these flowmeter/totalizers are often used in hard-to-access areas.

Socket-Connect Flowmeter/Totalizers for Water

Bond the unthreaded connections to PVC pipe with PVC cement and primer.

Flanged Flowmeter/Totalizers for Water

For secure connections in large pipelines with high flow rates, these flowmeter/totalizers have flanged ends.

Flowmeter/Totalizers for Water and Chemicals

To withstand water and a variety of caustic chemicals, these flowmeter/totalizers have a corrosion-resistant 316 stainless steel body.

Flowmeter/Totalizers for Oil and Fuel

Use with oil, gasoline, diesel fuel, and kerosene.

Flow Transmitters for Air

Calibrated for compressed air.

Compact Flow Transmitters for Water

Use these transmitters in areas with limited clearance.

Totalizers for Water

Measure the total flow volume of water in your system.

Washdown Totalizers for Water

The enclosure meets NEMA 4X to protect these totalizers from dust, washdowns, and corrosive liquids.

Totalizers for Grease

Install this totalizer on your grease gun to accurately measure grease dispensing and reduce waste.

Totalizers for Oil

Designed for use with light oils.

Remote-Reading Totalizers for Drinking Water

With a display that can be mounted up to 1,000 feet from the body, these totalizers are often installed in hard-to-access areas and remote locations.

Totalizers for Fuel

Measure the total flow volume of gasoline, diesel fuel, and kerosene.

Washdown Flowmeters for Water

For protection from dust, washdowns, and corrosion, these flowmeters have an enclosure that meets NEMA 4X.

Digital Flowmeters for Water with Solids

Also called Doppler flowmeters, these use ultrasonic waves to spot check flow rate throughout your system. They are for water containing particles 100 microns (similar to flour) or larger.
