General

FID series Dial Flow Rate Indicators Indicating the volume of flow

switch of fluid flowing through the pipe line. It is a variable orifice type

unit, which uses pressure drop across a spring loaded piston to create the

movement of a pointer across dial. The piston housing contains a

magnet, the movement of which is transferred to a radially magnetized magnet fitted to the pointer shaft.

Due to this magnetic linkage, the pointer magnet remains in a dry area and therefore the movement of the pointer

remains smoother for longer of operation.
