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 Gases
Commonly referred to as thermal mass flowmeters, these transmitters calculate flow rate by measuring how much they cool as air and other gases pass through them. This means they’re accurate even if there are temperature and pressure changes, unlike most other transmitters. Used to monitor flow or control equipment, these transmitters, also known as transducers, convert measurements to an electrical signal that is interpreted by receiving devices. As flow increases, the output signal increases. For your receiving device to interpret the signal, you will need to calibrate it for the measurement range and output signal of the transmitter. They only give accurate readings within the rated measurement range. A digital display makes it easy to check the flow rate and adjust settings. Mount these transmitters inline with your system.
These transmitters are calibrated with air. You can use them with other gases, but they will not be as accurate.
Adapter cords are required to connect these transmitters to a power source.
