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.

Flowmeters for Air

Measure the flow rate of compressed air.

Easy-Read Flowmeters for Air

The prominent dial is easier to read from a distance than a standard scale.

High-Pressure Flowmeters for Air

Rated for at least six times the pressure of standard flowmeters for air, these can withstand pressures of at least 600 psi.

Easy-Read High-Pressure Flowmeters for Air

With a prominent dial instead of a scale, these flowmeters are easier to read from a distance than other high-pressure flowmeters for air.

Panel-Mount Flowmeters for Air

For installation in instrument panels, these flowmeters have fittings on the back.

High-Accuracy Panel-Mount Flowmeters for Air

Choose these flowmeters for highly accurate flow rate measurements.

Impact-Resistant Panel-Mount Flowmeters for Air

For protection against damage, these flowmeters have a rugged, impact-resistant case.

Flowmeters for Inert Gas

The correlated scale and conversion charts let you use the same flowmeter for nitrogen, oxygen, argon, and helium.

Impact-Resistant Flowmeters for Water

A 304 stainless steel case protects these flowmeters from blows that could shatter the glass body.

Flow Transmitters for Air

Calibrated for compressed air.

Air Meters and Leak Detectors

Remote-Reading Airflow/Temperature Meters

With a probe on a cord, these meters access hard-to-reach places in duct.

Airflow/Temperature Meters

Airflow/Static Pressure Meters

This meter is often used to test airflow through supply and return grilles and air filters.
