High Pressure Variable Flow Monitor - Magnectic Follower
1. Flow Rate Moniters
Meter Type
High pressure magnetic follower flow rate monitor for; liquids @ 1.00 Specific Gravity, oil @ 0.873 Specific Gravity, and air @ 100 PSIG.
How It Works
Enclosed within a high-pressure casing (A), a high-strength magnet (B) in tandem with the sharp-edged annular orifice disk (C), is pressed towards the zero flow rate position by a linear rate compression spring (D). A tapered metering shaft (E) is positioned concentrically within the annular orifice disk and provides a variable-area opening that increases by the square of linear displacement of the orifice disk. Fluid flow creates a pressure differential across the orifice disk, pressing the magnet/orifice disk duo against the compression spring. The flow rate is read by aligning the magnetically coupled follower (F) with the graduated scale (G) located within the environmentally sealed window (H). The variable-area orifice design provides pressure differentials and orifice displacements that are linearly proportional to the fluid flow rate.
