Each type of product has a need to pay attention to, what about Goldman Sachs Electric detailed introduction of the following: 2, used for process control instruments, the best accuracy of 1%, usually 1.5%, turndown ratio of 10:1. 3. When the flow rate exceeds 100m3/h, the flow rate and pressure loss are large. 4. In hazardous locations, it is necessary to use intrinsically safe explosion-proof, explosion-proof type flowmeters, etc. When measuring high-temperature and low-temperature media, it is best to use jacket type... 5, metal rotor flowmeter to avoid the magnetic field interference on the flowmeter, if there is more than one meter dense installation or carbon steel process pipeline, it is best to keep a certain distance with the instrument. 6. If the measurement contains a large amount of ferromagnetic granular media flow, you need to install a magnetic filter and purge regularly. 7. Before installing new piping, flush the piping. 8. It is better to use the vertical installation mode of lower and upper outlets. The import and export guarantees that there is a straight pipe section with 5 times of instrument diameter. 9. The upstream of the flowmeter should be equipped with valves, and the flow control valve should be installed at the downstream 5~10 times of the instrument diameter. 10. It is better to connect the bypass pipe when installing the instrument to facilitate future maintenance such as maintenance and replacement. 11. When the measured medium is dirty, the tube and float should be cleaned in time. The above are its main considerations and I hope to help everyone.
Machinery parts is namely machine parts, it is basic components of machine.
Since the present of machine, the corresponding mechanical parts appear. But as also be a discipline, machinery parts separated from the mechanical structure and mechanics. With the development of mechanical industry, new design theory and method, new materials, new technology all appear one after another, then machinery parts entered a new stage of development. Theories such as finite element method and fracture mechanics, elastic hydrodynamic pressure lubrication, optimization design, reliability design, computer aided design (CAD), entity modeling (Pro, Ug, Solidworks, etc.), system analysis and design methodology has been gradually used in the research and design of machinery parts. Better combination of a variety of disciplines, combination of macro and micro to search new principle and structure, more dynamic and precise design, more efficient use of the electronic computer, the further development of design theory and method, is the important trend in the development of the discipline.

1. The metal rotor flowmeter is suitable for measuring the flow rate of gas, liquid and steam with small diameter and low flow velocity. Due to the influence of certain viscosity, it is not suitable for measuring high-viscosity medium, nor is it suitable for measurement of pulsating medium flow.
Metal rotor flow meter in the purchase, the installation process is mainly concerned about which aspects?
