Spiraflo Flowmeters

Good accuracy over 25 to 1 Turndown.  This is combined with inbuilt density compensation giving a compact installation requiring only 6 straight diameters upstream and 3 straight diameters downstream.

Operates on the well established spring loaded variable area principle:- a circular plate moves against a precision torsion spring with the resultant angle of deflection indicating flowrate.  An inbuilt temperature sensor allows for density compensation.  An input also allows for pressure input.  The resulting signals are fed into a flow computer to calculate the flowrate.
