    About Pressure Gauges
    industrial info icon

    Find a gauge with the right connection material and dial type—many with traceable calibration certificates.

    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.

    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.
    Pressure Tubes—Sensors with pressure tubes give more accurate measurements in applications with high air flow.

    Compression Tube Flow Transmitters for Gases

    Image of Product. Front orientation. Flow Transmitters. Compression Tube 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.
