Through many tests and improvements, ANDISOON summed up our experience and finally determined an inlet and outlet combined splitter cone, vacuum nickel-based brazing and heat treatment technology suitable for the CNG flowmeter produced by our company.
The measuring tube and the measuring tube joint are welded by argon arc welding; the diverter cone is inserted into the inner hole of the measuring tube joint in the axial and radial directions, and the diverter cone is positioned in conjunction with the measuring tube in the circumferential direction.
The interface joint is placed on the diverter cone, so that the outer cone surface of the diverter cone and the inner cone surface of the interface joint are positioned axially, and the inner hole of the interface joint is positioned radially. The interface joint and the diverter cone are also integrally pressed. Tight and welded with argon arc welding.
Beneficial effects:
When used in CNG flowmeters, this utility model can effectively improve the yield of CNG flowmeters, reduce the overall production cost, and scientifically ensure the overall performance of the CNG flowmeter. Moreover, this method and structure also have the characteristics of easy parts processing, low cost, and easy assembly and welding. The application of this method and structure will be of great help to the development of low-priced, high-performance domestic CNG flow meters, and will lay a solid foundation for the market dominance of domestic CNG flow meters.
After this process is applied in the production process of CNG flow meters, the deformation of the measuring tube and the uneven internal stress are minimized, which greatly improves the performance of the CNG flow meter. The yield can reach 95% and the overall cost is reduced. It is suitable for CNG flow. Large-scale mass production of CNG flow meters; it can bring the overall technology and accuracy of CNG flow meters to a new level; it will be of great help to the development of low-priced, high-performance domestic CNG flow meters and create a better market for domestic CNG flow meters. Dominance has laid a solid foundation.
UNIQUE FEATURES OF ANDISOON MASS FLOWMETER
Mass flow meters are known for their high accuracy, wide measuring range and reliable performance, and have been successfully used in various industries over the past many years.
Unlike other instruments that are limited to measuring liquids at normal pressure and temperature, ANDISOON excels in measuring under challenging conditions, including high pressure, high viscosity, and high and low temperatures. For example, when measuring CNG (compressed natural gas), the difficulty lies in the high pressure. However, ANDISOON's sensors can withstand high pressures, allowing the necessary increase in flow tube thickness, allowing the transmitter to detect signals with greater sensitivity. Therefore, ANDISOON's mass flow meters specially designed for CNG gas dispensers have been widely used in the domestic market
In the high-pressure sector, Andisoon has developed mass flowmeters for CNG gas charging, mass flowmeters for gas unloading columns, and mass hydrometers for hydrogenation machines with a maximum working pressure of 100MPa.
In the field of cryogenics, Andisoon has developed a backflow meter and a liquid phase injection meter for LNG refueling stations, with a minimum temperature of -196°C.
In the field of process control, Andison has developed a micro-bend type mass flowmeter, with a maximum flow rate of up to 300t/h, widely used in petroleum, chemical and other industrial conditions.
In the field of high-flow low-temperature metering, Andisoon has developed a U-shaped high-vacuum mass flowmeter, which has been patented and is used in liquefaction plants and ship loading and unloading operations.
Andison is committed to providing high-precision metering solutions, with product sizes ranging from DN3 to DN150, meeting your personalized metering needs.
