The use of gas mass flowmeter is also inseparable from our maintenance

The use of gas mass flowmeter is also inseparable from our maintenance. The volume of fluid is a function of fluid temperature and pressure, which is a dependent variable, while the quality of fluid is a quantity that does not change with time, space temperature, and pressure. As mentioned above, the flow measurement values ​​of commonly used flowmeters, such as orifice flowmeters, turbine flowmeters, vortex flowmeters, electromagnetic flowmeters, rotor flowmeters, ultrasonic flowmeters and oval gear flowmeters, are fluid volume flow. The amount of fluid involved in activities such as scientific research, production process control, quality management, economic accounting, and trade transfer is generally mostly quality. Measuring only the volumetric flow rate of the fluid by using the above-mentioned flowmeter often cannot meet people's requirements, and it is usually necessary to try to obtain the mass flow rate of the fluid. In the past, the quality of the fluid could only be obtained indirectly through methods such as correction, conversion, and compensation after measuring the parameters of the fluid such as temperature, pressure, density, and volume. When the measured fluid is under the condition of great changes in pressure, temperature and other parameters, if only the volume flow is measured, it will cause a large measurement error due to the change of the fluid density. In positive displacement and differential pressure flow meters, the density of the measured fluid may vary by 30%, which will cause a 30-40% error in the flow rate. With the increasing level of automation, many production processes have put forward new requirements for flow measurement. The course of a chemical reaction is controlled by the mass (rather than the volume) of the starting materials. The heating and cooling effects of steam and air flow are also proportional to the mass flow rate. Strict control of product quality, accurate cost accounting, machine and accurate fuel quantity control are also required. Therefore, the mass flow meter is an important flow measuring instrument. When using a gas mass flowmeter, we must not only operate it correctly, but also maintain it carefully so as not to affect its normal operation, and to a certain extent, it can also prolong the service life of the equipment. Today I will talk to you about it Maintenance method of mass flow meter. The first is its cleaning. The gas mass flowmeter is not like the pots and pans we usually use. The best way is to wipe off the stains on the surface with a soft cotton cloth. In the process of wiping, be careful not to use too much force to avoid the instrument from breaking. The second is its surface maintenance. Sometimes we need to disinfect it, but the general Disinfectant reagents are chemically too strong to be used, so alcohol is usually used for disinfection, and alcohol can also remove dust on the surface to a certain extent. The pressure of the gas measured by the CMF used in the gas dispenser is not lower than 20MPa, and the pressure is far greater than the atmospheric pressure. The high pressure changes the internal stress of the vibrating tube and increases the equivalent stiffness of the elastic tube, thereby increasing the vibration frequency of the vibrating tube and reducing the phase difference between the two tubes; when the gas flows through the vibrating tube, there is a pressure drop, which makes the vibrating tube The force is asymmetrical, which also affects the phase difference. When choosing a thermal gas mass flowmeter, we should choose according to the characteristics of the thermal type. It is very important to provide the correct parameters in the early stage for the selection, so as to avoid unnecessary losses caused by the wrong type affecting the production of the enterprise.

In the office, various are considered essential since they are used to achieve particular tasks in the office. Among these , mass flow meter, endress hauser ultrasonic flow meter, and coriolis mass flow meter emerson are widely used.

Beijing Sincerity Automatic Equipment Co., Ltd’s core aim is to afford high-quality products with the concept of manufacturing technology.

Beijing Sincerity Automatic Equipment Co., Ltd agreed, noting that successful social marketing will become an even more important component of overall marketing strategies, and that marketers will have to think longer, harder and more creatively if they want to be able to fulfill the newly created potential of insertion ultrasonic flow meter.
