LZB-4B all stainless steel glass rotor flowmeter air nitrogen all stainless steel glass tube float flowmeter

Description :

All stainless steel glass rotor flowmeterMainly used for detecting the flow rate of corrosive liquids and gas media, such as strong acids and bases, oxidants, strong oxidizing acids, organic solvents, and other corrosive gas or liquid media. The main measuring components of the flowmeter are a vertically installed lower small upper large conical glass tube and a float that can move up and down inside. When the fluid passes through the conical glass tube from bottom to top, a pressure difference is generated between the upper and lower parts of the float, and the float rises under this pressure difference. When the upward force, buoyancy, and viscous lift acting on the float are equal to its gravity, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow rate 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 measure of flow rate. The glass tube rotor flowmeter is mainly developed for use in various sectors such as chemical, petroleum, light industry, pharmaceuticals, fertilizers, synthetic fibers, food, dyes, environmental protection, and scientific research, to measure the flow rate of single-phase non pulsating (liquid or gas) fluids.

All stainless steel glass tube float flowmeterIt mainly consists of a conical glass tube that expands from bottom to top and a stainless steel float that moves up and down with the fluid flow rate (Figure 3). When the fluid flows through the conical tube from bottom to top, the lift S generated by the kinetic energy of the fluid on the float and the buoyancy A of the fluid cause the float to rise. When the sum of the lift S and buoyancy A is equal to the weight G of the float itself, the float is in equilibrium and stable at a certain height position. The scale on the conical tube indicates the flow rate value of the fluid. The price of argon glass rotor flowmeter WB indicates with regulating valve, W indicates without regulating valve, WBF indicates with regulating valve anti-corrosion type, WF indicates without regulating valve anti-corrosion, and the reading position of the float in the flowmeter is shown in Figure 2: the cone tube of GD-LZB/LZB - () F flowmeter is a smooth inner wall tube (see Figure 4), and for flowmeters with a diameter of DN15 or more, the float moves up and down through a guide rod to maintain stability; There are three guiding ribs on the inner wall of the cone tube of the GD-LZJ/LZJ-() F flowmeter, which keep the float stable (see Figure 4). Flow meters with a diameter of DN10 or less are connected by hoses and equipped with needle shaped flow control valves; Flow meters with a diameter of DN15 or above shall be connected with flanges. The material, model, specification, and technical parameters of the components that come into contact with the measured fluid are LZB (WB) with a regulating valve and LZB (W) without a regulating valve. All stainless steel flanges, floats, guide rods, support plates, and bolts are made of stainless steel 304 (1Cr18Ni9Ti), model GD-LZB - () B. If 316 is required for the liquid receiving material, the model is GD-LZB - () Bo, which needs to be customized. If stainless steel lined with PTFE is required, the model is GD-LZB - () BF (or BoF), which needs to be customized. The all PTFE base, float, and needle valve are made of polytetrafluoroethylene (PTFE). The support plate, screws, etc. are made of stainless steel LZB - () WB, W-type flow meters, which can detect small flow rates of gases or liquids. They have a compact appearance and are widely used in various analytical instruments, environmental protection equipment, medical equipment, and other testing instruments. The WB type has a regulating valve, while the W type has a structure without a regulating valve.
