1. What gas flow meters do everyone use? Currently, most of the various types of gas flow meters used measure the volumetric flow rate of gases. The main feature of the commonly used Ziyou instrument series gas mass flowmeter is that it is not affected by temperature and pressure changes. Its display reading directly indicates the mass flow rate of the gas, and it is installed in the pipeline to record the amount of dry and bright gas flowing through. It can measure various types of gases such as blast furnace gas flow meter, coke oven gas mass flow meter, gas, air, nitrogen, acetylene, phosgene, hydrogen, natural gas, nitrogen, liquefied petroleum gas, hydrogen peroxide, flue gas, methane, butane, chlorine, gas, biogas, carbon dioxide, oxygen, compressed air, argon, toluene, benzene, xylene, hydrogen sulfide, sulfur dioxide, ammonia, etc. When a triangular cylindrical vortex generator is set up in a steam fluid, regular vortices are alternately generated from both sides of the vortex generator, which are called Karman vortices. The vortex columns are asymmetrically arranged downstream of the vortex generator. Gas flowmeter is a new type of flowmeter that measures fluid flow in closed pipelines based on the Karman vortex principle. Due to its excellent medium adaptability, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure the volumetric flow rate and mass flow rate under standard conditions, making it an ideal alternative to throttling flow meters. 2. What are the precautions for using MFM/MFC?
As precision instruments, MFM (mass flow meter) and MFC (mass f
1. Basic operation and storage Reading instructions: Before use, it is necessary to read the product manual and related technical information carefully, understand the equipment parameters, operating specifications, and safety warnings.
. Handle with care and keep properly: The internal structure of MFM/MFC is precise and should avoid impact or strong vibration. When stored, it should be placed in a dry, non corrosive gas, and stable temperature environment, away from magnetic field interference.2. System Design Considerations: System design should balance functionality and reliability, with a focus on the following aspects: air source purification: installing filters to remove particulate impurities, prevent contamination of sensors or valves, and extend equipment life.
. Anti backflow design: Install a one-way valve at the outlet of the MFC in the reaction system to prevent damage to the equipment caused by reactant backflow in abnormal situations. High pressure system configuration: Install a back pressure valve (or throttling device) and pressure gauge downstream of MFC to ensure stable working pressure difference and avoid pressure fluctuations affecting accuracy. Special gas treatment: Silane and other easily crystallizable gases: The system must be sealed, and the pressure regulator cannot be ignored during leak detection; If necessary, design a nitrogen purge bypass or maintain positive pressure to prevent crystal blockage. Harmful gas system: using low leakage joints such as VCR, strict leak detection; The gas cabinet needs to be equipped with an exha
