Economical Variable Area Piston Type Flowmeter for fluids or gases.

How It Works
Enclosed in a transparent housing is a piston/shuttle and spring that is calibrated to provide a direct view of flow rate for fluids or gases. The orange colored shuttle lines up with flow scale on the side of the meter. The transparent housing also acts as a Sight Flow Indicator enabling visual observation of the media.
