Problems with the use of mass flow controllers
Problems with the use of mass flow controllers Mass flow controllers can perform both gas flow metering and process control applications. The mass flow controller was introduced with the advanced technology of the United States. Without the need of temperature and pressure compensation, the mass flow rate of the fluid was measured directly. The outstanding features of the mass flow controller are: no moving parts; low pressure loss; wide range ratio; high accuracy; high reliability; simple installation and easy operation. The orifice plate and differential pressure flow meter can be completely replaced in all fields. We all know what problems should be paid attention to when using mass flow controllers? The following mass flow controller manufacturers introduce to everyone. 1. When measuring the gas flow, it is necessary to maintain a constant constant heat capacity, so it cannot be used to measure the gas composition changes. 2. The gas to be measured must be dry. Do not approach the critical point during the measurement of the mass flow controller to avoid unstable conditions such as liquefaction phase change. 3. The measurement of easily vaporized liquids should pay attention to the influence of the heating of the flowmeter on the measured liquid. If necessary, select the mass flow controller of the cooling element (negative heating element). 4. Bubbles cannot be mixed in the liquid and cannot be used for miscible flow or fluid that may produce phase change. 5, applied to the pipeline containing smoke and dust gas, if necessary, installed in the instrument separator or filter. By paying attention to these items, the measurement error of the mass flow controller can be reduced and the measurement result can be more accurate. In this era, we are paying more and more attention to the monitoring of gas, because the gas mass flow needs to be controlled, so that it can bring great help and then it can be poetic. Life provides important protection. Today is a high-tech era, so we all feel that the mass flow controller is a very important product and it is a product with a wide range of uses. Therefore, there are many advantages. Mass flow controllers are used in many gases, such as fuel gas, and so on, as well as in the gas side. At the same time, it can also be widely used in oil extraction projects. In addition, on the burner side, processed foods or other aspects, etc., are inseparable from such products, it can be seen that there are many advantages of the mass flow controller, so the prospects for the development of such products very good.
