Overview

The LZB/LZJ series of glass rotor flow meters are widely used in chemical, petroleum, light industry, medicine, environmental protection, food and measurement testing, scientific research and other departments. The flow meters LZB - () F/LZJ - () F series measure single-phase non pulsating fluids (liquids or gases) and have strong corrosion resistance. They can detect the flow of acids (except hydrofluoric acid), alkalis, oxidants and other corrosive gases or liquids. They are suitable for industries such as chemical, pharmaceutical, papermaking, sewage treatment, etc

Glass rotor flowmeterPrinciple and Structure

corrosion-resistant typeGlass rotor flowmeterGlass rotor flowmeterIt mainly consists of a glass cone tube that expands from bottom to top and a float that moves up and down with the fluid flow rate (Figure 3).

corrosion-resistant typeGlass rotor flowmeterWhen the fluid flows through the conical tube from bottom to top, the sum of the lift S and buoyancy A generated by the fluid's kinetic energy on the float is equal to the float's own gravity G. When 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.Glass rotor flowmeterThe reading position is shown in Figure 4

corrosion-resistant typeGlass rotor flowmeterThe glass cone tube of LZB/LZB - () F flowmeter is divided into smooth inner wall tubes (see Figure 5), with a diameter of DN15 or moreGlass rotor flowmeterThe float moves up and down through the guide rod to maintain stability: LZJ/LZJ() F seriesGlass rotor flowmeterThere are three guiding ribs on the inner wall of the glass cone tube to keep the float stable (see Figure 6). Flow meters with a diameter of less than 10 are connected by hoses and equipped with needle type flow meter regulating valves; Diameter above DN15Glass rotor flowmeterAdopt flange connection.

Note: Special traffic can be customized

All stainless steel typeLZB-( )B/BF LZB-( )B0/B0F

The flange, float, guide rod, support plate, and bolts are all made of 304 stainless steel material, with the model LZB - () B

If 316 is required for the liquid receiving material, the model is LZB - () B0 and customization is required

If stainless steel lined PTFE is required, the model is LZB - () BF (316 is B0F), which needs to be customized

The all PTFE type (DN3~DN10) model is LZB - () F4

The base, float, and needle valve are made of polytetrafluoroethylene (PTFE), while the support plate and screws are made of stainless steel material
