Clear Tube Flow Meters - Series PT/PS

The variable area Flowmeter using a float in a tapered tube made of special plastic materials.

Working principle

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 flowmeter remains constant over the entire flow range, since it is related to the fluid density and the float weight and dimensions. Flow indication is achieved since the area of flow increases as the flow rate increases.
