1. What does the orifice flowmeter Dg50 mean?

DN is the nominal diameter, which is the common diameter for various pipes and pipeline accessories. Pipes and pipeline accessories of the same nominal diameter can be connected to each other and have interchangeability It is not the actual outer or inner diameter of the pipeline, although its value is close or equal to the inner diameter of the pipeline; DG50=GN50 in millimeters

2. What is the symbolic representation for flow calculation? The symbol of a mass flowmeter in a process flow diagram represents that the volume of the fluid is a function of fluid temperature and pressure, and is a dependent variable, while the mass of the fluid is a quantity that does not change with time, spatial temperature, or pressure. As mentioned earlier, commonly used flow meters such as orifice flow meters, turbine flow meters, vortex street flow meters, electromagnetic flow meters, rotor flow meters, ultrasonic flow meters, and elliptical gear flow meters measure the volume flow rate of the fluid. The fluid volume involved in scientific research, production process control, quality management, economic accounting, and trade handover activities is generally quality. The use of the above-mentioned flowmeter to measure only the volumetric flow rate of the fluid often cannot meet peoples requirements, and it is usually necessary to find ways to obtain the mass flow rate of the fluid. Previously, the mass of a fluid could only be indirectly obtained through methods such as adjusting the number of measurements, conversion, and compensation after measuring parameters such as temperature, pressure, density, and volume. This measurement method involves multiple intermediate steps, making it difficult to ensure and improve the accuracy of mass flow measurement. With the development of contemporary science and technology, there have been some direct measurement methods and devices for mass flow, which have promoted the progress of flow measurement technology.
