1. Structural principle of metal tube float flowmeter
Metal tube float flowmeter is a commonly used flow measurement instrument, and its structural principle is as follows: Working principle: The float of the metal tube float flowmeter is placed in the measuring tube, and when the fluid flows through the measuring tube, the float will be subjected to the force of the fluid. As the flow rate changes, the float will move up and down inside the measuring tube. When the float moves to a certain position, the buoyancy it receives reaches an equilibrium state with its own gravity. At this point, a circulation gap will be formed between the float and the orifice plate (or cone tube), and the area of this gap will remain constant. And the annular gap area is directly proportional to the rising height of the float, that is, the position of the float rising in the measuring tube can represent the size of the flow rate. In order to transmit the position information of the float to indicate the flow value, a magnet is installed inside the float. The change in float position is transmitted to the external indicator through an internal magnet, allowing the indicator to correctly display the current flow rate value. This magnetic coupling transmission method eliminates the need for direct contact between the indicator housing and the measuring tube. Therefore, even with limit switches or transmitters installed, the instrument can still be used under high temperature and high pressure working conditions. The metal tube float flowmeter is mainly composed of two parts: the sensor measuring tube and the float. The measuring tube is a channel for fluid flow, and the float moves in it with the change of flow rate. The liquid recei
