Tecfluid 6000 Series

Description

Tecfluid 6000 Series

Variable area glass tube flow meter

Working principle

The Tecfluid 6000 Series flowmeters work according to variable area principle, which is obtained by a float that moves inside a borosilicate glass tapered tube.The fluid flows up through the tapered tube forcing the float to a position with sufficient free area to enable the flow to pass, where there is an equilibrium of forces: – E = force of the fluid flow – Pf = weight of the float – Al = free area of flow (Al = Ac, tube area, – Af, float area) Each position of the float corresponds to a value of flow rate.
