Badger Meter Headland Variable Area Air Flow Meter, 1/2 in. Female NPTF Aluminum Fitting

Aluminum air flowmeters install in any position. This variable area type flowmeter utilizes a spring and piston type assembly. Differential pressure caused by flow between the metering cone and the piston/magnet assembly moves the piston against a retaining spring.
