Working principle and application of glass rotor flowmeter
2012-2-21 16:29:34

的主要测量元件为一根垂直安装的锥形玻璃管及在内可上下移动的浮子。 The main measuring element of the glass rotor flowmeter is a vertically mounted conical glass tube and a float that can move up and down inside. The cone tube is at the end, and when the fluid passes through the cone glass tube from bottom to top, a pressure difference occurs between the upper and lower parts of the float, and the float rises under the effect of this differential pressure. When the force that causes the float to rise is equal to the combined forces of gravity, float, and viscous force, the float is in a balanced position. 的流体流量与浮子上升高度,即与玻璃转子流量计的流通米面积之间存在着一定的比例关系,浮子的位置高度可作为流量量度。 Therefore, there is a certain proportional relationship between the flow rate of the fluid flowing through the glass tube rotor flowmeter and the rising height of the float, that is, the flow meter area of the glass rotor flowmeter. The position height of the float can be used as a flow measurement. Corrosion-resistant series of glass rotors are mainly composed of a conical glass tube, a float, upper and lower bases and supporting members.
主要用于化工、石油、轻工、医药、化肥、化纤、食品、染料、环保及科学研究等各个部门中,用来测量单相非脉动(液体或气体)流体的流量。 Ordinary glass rotor flowmeter is mainly used in various departments such as chemical industry, petroleum, light industry, medicine, chemical fertilizer, chemical fiber, food, dye, environmental protection and scientific research to measure the flow rate of single-phase non-pulsating (liquid or gas) fluid. . Corrosion-resistant glass rotor flowmeters have strong corrosion resistance, and are mainly used for the detection of corrosive liquids and gaseous medium flows, such as strong acids (except hydrofluoric acid), strong alkalis, oxidants, strong oxidizing acids, organic solvents and The flow detection of other corrosive gas or liquid media is suitable for chemical, pharmaceutical, papermaking, sewage treatment and other industries.
