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.

Totalizers for Water

Measure the total flow volume of water in your system.

High-Accuracy Totalizers for Water

Three times more accurate than standard totalizers for water, these are rated for ±1.5% accuracy.

High-Temperature Totalizers for Water

Withstand temperatures of at least 194° F.

Washdown Totalizers for Water

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

Totalizers for Fuel

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

High-Accuracy Totalizers for Fuel

More than twice as accurate as standard totalizers for fuel, these are rated for ±2% accuracy.

Totalizers for Oil

Designed for use with light oils.

Totalizers for Drinking Water

These totalizers meet NSF/ANSI Standard 61 for use in drinking water systems.

Flanged Totalizers for Drinking Water

Flanged ends provide secure connections in large pipelines with high flow rates.

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.

Flowmeters

Easy-Read Flowmeters for Water

Instead of a scale, these flowmeters have a prominent dial that’s easy to see from a distance. Dial displays readings in gallons.

High-Pressure Flowmeters for Water

Rated for pressures up to 3,500 psi.

Easy-Read High-Pressure Flowmeters for Water

For easier reading from a distance, these flowmeters have a prominent dial instead of a scale. They can withstand pressures up to 3,000 psi.

Full-View Flowmeters for Water

The transparent body lets you inspect water color and clarity in addition to measuring the flow rate.

Easy-to-Install Full-View Flowmeters for Water

Union nuts on both ends make it easy to install and remove these flowmeters from your system.

Washdown Flowmeters for Water

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

Pipe-Mount Flowmeters for Water

Install these flowmeters without disassembling your pipeline. Drill a hole in an existing run of PVC pipe and secure the flowmeter with the included clamps.
