Kyue Variable Area Flowmeter With Plastic Tube Flow Meter OEM ODM
1.Product Overview
The plastic tube float flowmeter is a visual flow instrument based on the variable area measurement principle. Its measurement tube is made of transparent engineering plastics (such as polycarbonate PC, polysulfone PSU, or acrylic resin PMMA). The flow rate is indicated by the vertical position of a float inside the tapered tube, which changes with the flow rate. This meter features a simple structure, intuitive reading, cost-effectiveness, and corrosion resistance. It is widely used for low-pressure, small-flow measurement of clean liquids or gases.
