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.

Low-Pressure Differential Gauges with U-Tube
Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure. They are commonly used to indicate clogged filters.
Magnet-mount gauges can be moved for use in multiple locations.

- For Use With: Air, Argon, Carbon Dioxide, and Hydrogen
- Accuracy: Not Rated (Not Graded)

Air Sensors for Differential Pressure


Use these sensors with differential pressure gauges and switches to measure the static pressure drop across air filters, cooling coils, and blowers in air-handling equipment. Install them in duct through a hole and connect to your gauge with tubing.
Sensors with pressure tubes give more accurate measurements in applications with high air flow.

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.
