Principles and Structure
的主要测量元件为一根小端向下,大端向上垂直安装的锥形塑料管及其在内可以上下移动的浮子。 The main measuring element of the plastic tube rotor flowmeter is a conical plastic tube with a small end facing downward and a large end facing upward, and a float that can move up and down inside. When the fluid flows through the conical plastic tube from bottom to top, a pressure difference is generated between the upper and lower parts of the float, and the float rises under the action of this differential pressure. When the force that causes the float to rise is equal to the combined forces of gravity, buoyancy, and viscous force, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the flow rate of the fluid flowing through the flowmeter and the rising height of the float, that is, the flow area of the flowmeter. The position height of the float can be used as a flow measurement.
