在使用时，在流量变化的时候，浮子在测量管中，会随之向上移动，当浮子与孔板或锥管间的流通环隙面积保持一定时，这就说明某一位置的浮子所受的浮力F与浮子重量W已达到平衡状态。 When the metal tube float flowmeter is used, when the flow rate changes, the float will move upward in the measuring tube. When the area of the ring gap between the float and the orifice plate or the cone tube remains constant, this indicates that a certain The buoyancy F and the weight W of the float at the position have reached an equilibrium state. 也可正常使用工作。 The position where the float rises in the measuring tube represents the amount of flow, which indicates that the area of the ring gap is proportional to the height of the float. When the position of the float is transferred from the internal magnet to the external indicator, the indicator will correctly indicate this Time, the indicator housing will not be in direct contact with the measuring tube at this time. Therefore, under high temperature and high pressure working conditions, the limit switch or transmitter is installed, and the instrument can also work normally.
The float flowmeter is suitable for measuring liquids and gases, because it uses the variable area measurement principle. Including indicating type, high voltage type, jacket type, explosion-proof type, electric remote transmission type, and corrosion-resistant all-metal structure. ）标准模拟信号输出和现场指示的功能；（ 2 ）累积，数字通讯，现场修改测量参数；（ 3 ）不同的供电方式；（ 4 ）带有磁性过滤器和特殊规格品种。 Functions include ( 1 ) standard analog signal output and on-site instructions; ( 2 ) accumulation, digital communication, and on-site modification of measurement parameters; ( 3 ) different power supply methods; ( 4 ) with magnetic filters and special specifications . This flow meter is also suitable for the measurement of ground flow under complex, harsh environmental conditions and various media conditions. It is widely used in petroleum, chemical, power generation, pharmaceutical, food, water treatment and other industries.
