_1280x1280__56594.1620410686.jpg?c=2 "Badger Meter Hedland Variable Area Air & Compressed Gas Flow Meter, Aluminum, 1/4 in. Female NPT")
The Hedland air and compressed gas meter provides an economical solution for operators who need a quick, visual indication of flow, without the use of additional electronics. Simple to read thanks to an easy-to-read linear scale and 360° rotatable guard/scale. Has a magnetic coupling that eliminates the need for mechanical linkages that leak, loosen and wear over the life of competitive meters. Pneumatic flow meter is offered with a standard multi-pressure flow scale has a vertically graduated scale, calibrated for air in standard cubic feet per minute. This configuration requires that a pressure gauge be installed at the meter inlet.
