Metal float flowmeter

Principle of metal float flowmeter: When the fluid flows through the measuring tube from bottom to top, the float will gradually rise due to buoyancy and fluid thrust. When the gravity, buoyancy, and fluid thrust of the float are balanced, the float will hover at a certain position in the measuring tube. When the flow rate of the fluid metal tube float flowmeter increases, the thrust also increases, and the displacement of the float will also increase. After the displacement of the float increases, the annular gap between the orifice plate or cone tube will also increase, which will pass through a larger flow rate. Therefore, the metal tube float flowmeter is a variable area flowmeter.
