How does a mass flow controller measure the flow rate of a mixed gas?

The mass flowmeter adopts a thermal measurement method, which measures the flow rate by the amount of heat carried away by the separated molecules. Because it uses a thermal measurement method, the measurement results will not be affected by changes in gas temperature and pressure.. When gas flows through the heating element, it takes away heat, and the amount of heat taken away is proportional to the flow rate and density of the gas. In order to maintain a fixed temperature difference between the two temperature sensors, the circuit needs to provide more power to the heating element. The output power of the circuit is related to the mass of the fluid, and the flow rate is measured accordingly. This method is commonly used in Japanese engines. Another commonly used method for measuring intake air volume in engines is the velocity density method, which is widely used by European and American engine manufacturers.

2. There is no differential pressure when measuring the mixed gas of trichlorosilane hydrogen using an Anuba flowmeter.

First of all, there is currently no flowmeter on the market that can fully measure gas/liquid mixed media. Although some manufacturers claim to have developed such flowmeters, they are generally a system (including gas-liquid separation devices and flow meters) and have limitations on the range compared to gas and liquid concentrations.

. The situation where the Anuba flowmeter measures the mixed gas of trichlorosilane hydrogen without differential pressure, according to your description, may be caused by the following reasons:

1. The gas flow rate in the pipeline itself is very low

2、 Is the installation of the pressure tapping pipeline correct? For your wet medium containing liquid, if the differential pressure transmitter is installed below the pipeline, is there a liquid accumulation tank installed.

3、 The problem of blockage in the pressure hole. Addendum: There is no problem with measuring the vertical installation of steam itself. The key is that the positions of the two balance tanks (condensing tanks) should be on the same horizontal plane, and temperature and pressure compensation is also required to accurately measure the mass flow rate of Weiyuan Sakura. ~~Professional manufacturer of flow meters, welcome to discuss and negotiate~

3. What is a mass flow meter

1. What is a mass flow meter: Mass Flow Meter (MFM) is a precision sensor used to quickly and accurately measure the flow rate of process gases. The mass flow meter mentioned here is mainly used for low-pressure, low flow single or mixed gases. Low pressure is generally below 1Mpa, and the maximum can reach 3Mpa; The flow range is generally 0.1 sccm to 5000 slpm; Single gases such as common air, helium, argon, etc. require relative dryness and purity; For mixed gases, it is necessary to specify the type and proportion of gases. 2. What parameters can be obtained from a mass flow meter? The Yidu mass flow meter can accurately obtain five major parameters of gas: real-time temperature, pressure, operating flow rate, standard flow rate, and cumulative flow rate. The units of a mass flow meter are generally SLPM (liters per minute under standard conditions) and SCC
