Refill U-tube gauges.

Measure small changes in air pressure with these gauges. They are commonly used to indicate clogged filters and to monitor fans and blowers.

A band of green, yellow, and red provides a clear indication of changes in differential pressure.

Use in medium-pressure applications up to 1,500 psi.

Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements.

Also known as pitot tubes, these can be used with manometers to measure air flow rate.

View readings at the source with the dial indicator or remotely using a receiver—these transmitters measure the difference in pressure between two inputs in liquid applications.

Remotely monitor the difference in air pressure between two inputs with these transmitters.

Get the flexibility of a differential pressure transmitter and a switch in one. These transmitters can work as a traditional transmitter using an analog output but also have electronic switch outputs and IO Link compatibility, making them great for advanced automation applications.

Measure the difference in pressure between two process lines without needing to program your receiving device to correct for errors. These transmitters automatically compensate for errors caused by vibration and temperature changes.

These versatile meters display airflow and one other measurement simultaneously. They’re also known as anemometers or vane meters.
