Gilflo Flowmeters

Good accuracy over an unrivalled 100 to 1 Turndown.  This is combined with installation requiring only 6 straight diameters upstream and 3 straight diameters downstream and means the Gilflo offers a very compact installation. 

Operates using the Spring Loaded Variable Area principle:- As flowrate increases, a profiled cone is deflected against a precision spring which varies the orifice area.

The resultant differential pressure across the cone and orifice is measured using a Multivariable Transmitter or DP Transmitter to obtain the flowrate.
