Metal tube flowmeter F820s series
Model: F821, F822, F823, F824, F825, F826, F827
 
Description

Metal tube rotameter is basically a variable area
flow meter. The differential pressure across the annulus
area is constant and the flowrate is measured as a function
of the position of annulus area created by float position.
The position of the float is sensed by a magnet and
indicated on the dial in terms of flowrate.
