Application of Mass Flowmeter in Industrial Welding Protection Gas

Application of Mass Flowmeter in Industrial Welding Protection Gas
The volume of the fluid is a function of the fluid temperature and pressure, a dependent variable, and the mass of the fluid is an amount that does not vary with time, space temperature, and pressure. As mentioned earlier, flowmeters, such as orifice flowmeter, turbine flowmeter, vortex flowmeter, electromagnetic flowmeter, rotor flowmeter, ultrasonic flowmeter and elliptical gear flowmeter, are commonly used in flowmeters. Volume flow. The amount of fluid involved in activities such as scientific research, production process control, quality management, economic accounting and trade handover is generally quality. Using the flowmeter only to measure the volume flow of the fluid is often unable to meet the requirements of people, usually also need to try to get the mass flow of fluid. It is only possible to obtain the quality of the fluid indirectly by means of correction, conversion and compensation after measuring the parameters such as temperature, pressure, density and volume of the fluid. This measurement method, the intermediate links and more, the accuracy of mass flow measurement is difficult to be guaranteed and improved. With the development of modern science and technology, there have been some direct measurement of mass flow measurement methods and devices, thus promoting the flow measurement technology progress.
In the modern industrial control, the stability and accuracy of the full realization of the need for accurate measurement of gas in the industrial welding of the protection of gas output is also a more careful control of the steps to ensure that does not pollute the environment, Good to complete the welding task, the mixture of carbon dioxide and argon can control precision.
Siargo MF4000 Series Gas Flow Meters provided by Shenzhen ISweek  

The MF4000 Series Mass Flow Meters are designed for flow metering of low velocity airflow in gas lines with diameters of 3 mm to 8 mm. The bayonet design provides a simple installation for the user to meet the needs of the user to measure multiple gas lines. Plastic bayonet can be easily carried out mechanical interface conversion, applied to different low-cost environment. The table can be used for anesthesia machine electronic form, can also be applied to other industries.
The sensor can directly measure the gas mass flow, low pressure loss. Suitable for clean air or nitrogen flow monitoring, can also be used for environmental samplers (such as chromatographic equipment, etc.)
FS4003 flow sensor, pipe diameter of 3mm, low cost measurement range up to 5SLPM; for particle counters and various types of analytical instruments.
FS4008 flow sensor, the pipe diameter of 8mm, measuring range up to 50SLPM; can be used for equipment, clean gas detection, such as: air sampling machine, gas analyzer.
