The Parker S series variable area flowmeter measures a liquid flow rate of 0.2L/min to 2L/min. This variable flow indicators with a float inside an outer graduated flow scale on the viewing sleeve. It utilises the technique of differential pressure across a piston. As the flow increases, the piston moves against a calibrated spring.
