Flowmeter(Plastic Tube)
Model: PT11,PT12,PS31,PS32
Manufacturer: TECFLUID(ITALIA)
Introduction:
Variable area flow using a float in a tapered tube made from special plastic materials.
The fluid flows up through the tapered tube forcing the float to a position with sufficient free area to enable the flow to pass.This free area is related to the flow rate, the weight of the float and the density and viscosity of the fluid.The pressure drop across the flow meter remains constant over the entire flow range. This occurs because the pressure drop is related to the fluid velocity and area of flow, the area of flow increases as the flow rate increases.
