(以下简称仪表)是带有透明锥型管直接观察浮子(转子)高度的指示式仪表,它在恒压差条件下利用流通截面的变化来测量非混浊的液体或气体的流量。 Glass rotor flowmeter (hereinafter referred to as the meter) is an indicator meter with a transparent cone-shaped tube to directly observe the height of the float (rotor). It measures the flow of non-turbid liquid or gas under constant pressure differential conditions by using the change of the flow cross-section. . Its characteristics are simple structure, reliable use, easy installation, convenient maintenance, and small pressure loss. Meters are widely used in petroleum, chemical, metallurgy, chemical fiber, dye papermaking, environmental protection equipment, medical equipment, food, sugar, brewing and supporting facilities for scientific test equipment. Principle and structure: The main measuring element of the meter is a vertically-mounted cone-shaped glass tube with a small end facing down and a large end pointing upward (a conical tube for short) and a float that can move up and down inside. When the fluid flows through the cone from bottom to top, a differential pressure is generated between the upper and lower parts of the float, and the float rises under this differential pressure. When the force that causes the float to rise and the gravity, buoyancy, and viscous force on the float When the resultant force is equal, the float is in a balanced position. Therefore, there is a certain proportional relationship between the flow of flow through the meter and the rising height of the float, that is, the flow area of the meter. The position height of the float can be used as a flow measurement.
通径为∮4、∮6、∮10采用软管连接。 The diameter of LZB glass rotor flowmeter is ∮4, ∮6, ∮10, which are connected by hoses. The diameters are ∮15, ∮25, ∮40, ∮50, ∮80, and ∮100 with flange connection. The base material of LZB-F anti-corrosive flowmeter is ∮4, ∮6, ∮10. The base material is 1Cr18Ni9Ti. It is connected by a hose. LZB-F corrosion-resistant flowmeter with a diameter of ∮15-∮100 is mainly composed of glass cones, plastic-float floats, upper and lower liner bases, upper and lower stops, support plates, front and rear housings, seals, and seal films. . Corrosion-resistant flow timepieces are connected by flanges. The LZB-F type corrosion-resistant flowmeter floats with diameters of ∮80 and 带有 100 are equipped with guide rods, so that the float moves up and down to move the protective cone to avoid damage. . The parts in contact with the medium of the anti-corrosive flowmeter are made of high-grade and corrosive materials, polytetrafluoroethylene (F4) and polyperfluorohexapropylene (F46). The exterior is made of epoxy resist paint and amino baking varnish. Good corrosion resistance. It is very reliable and effective in measuring the flow of strong acids (except hydrofluoric acid), strong bases, oxidants, strong oxidizing acids, organic solvents and other corrosive gases and liquids in various corrosive media.
是高精度流量计，测量管为玻璃管并由四根立柱支撑于上下基座之中。 The glass tube rotor flowmeter is a high-precision flowmeter. The measurement tube is a glass tube and is supported in the upper and lower bases by four columns. Mainly used for chemical analysis instruments and experimental research equipment, panel installation. The flowmeter can be divided into panel type and pipeline type, of which the panel type is divided into with and without regulating valve.
The base material is divided into plastic and stainless steel. The plastic base can be made of PVC and polytetrafluoroethylene (PTFE) according to the fluid medium. Stainless steel is generally made of 304 and plastic is made of PVC.
