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.

Impact-Resistant Flowmeters for Water

A 304 stainless steel case protects these flowmeters from blows that could shatter the glass body. They measure the flow rate of water and can also be used with air. All install directly in your pipeline. Fittings are 316 stainless steel for corrosion resistance in harsh environments.

Panel-Mount Flowmeters for Air
Monitor the flow rate of compressed air from your instrument panel—these flowmeters have fittings on the back for panel mounting.
Flowmeters with a flow-control knob let you open and close the valve at the inlet to adjust the flow rate within the range.
Certificate of calibration traceable to NIST states that the flowmeter has passed a test for accuracy.
Flowmeters with two pipe sizes have internal NPT female threads and external NPT male threads.
316 stainless steel fittings are more corrosion resistant than brass and PVC fittings.
Optional repair kit includes replacement seals.

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. They measure the flow rate of compressed air in your system and directly install in your pipeline. The dual scale shows readings in both standard cubic feet per minute and cubic centimeters per minute and rotates 360° for viewing at multiple angles.

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. They’re rated for pressures up to 3,000 psi. They measure the flow rate of compressed air and are designed for installation directly in your pipeline.

Flow Transmitters for Air

Calibrated for compressed air, these transmitters send flow-rate readings to data recorders, loggers, and displays. They have compression tube connections that bite down on hard metal and plastic tubing for a secure seal. The digital display shows the flow rate, so these transmitters can also be used as flowmeters. Fittings are 316 stainless steel for corrosion resistance in harsh environments.
