PURPOSE: To enable confirmation of a normal-direction gas flow without displaying a reverse flow gas due to pressure fluctuation by limiting the maximum number of display digit of a display device, and lighting-displaying a gas flow of a smaller quantity than the display digit. ;CONSTITUTION: ...
Gas meter, device for measuring the quantity or rate of flow of a gas. Types of gas meters (by operating principles) include displacement, velocity, head, thermal, acoustic, and tracer. An example of the displacement principle is the bellows-and-diaphrag

PURPOSE: A precision flow meter for displaying gas flow rate and dynamic pressure is provided to reduce cost by setting minute flux, constant pressure, and dynamic pressure.;CONSTITUTION: A precision flow meter(1) comprises a display scale(3) and a pressure gauge(2). The display scale checks...
The development of high-speed GC (HSGC) began in 1962 when Desty described a GC system that used a 2-meter long, 0.07mm internal diameter open-tubular column, a FID detector, and a split injector to separate a 15 component mixture in 2s [104]. In order to obtain a sufficiently narrow...
It is controlled by the monitoring system and can be automatically shut down when the GE is not working, and automatically open when the GE is working. 10.3 The airtightness of the container meets the noise requirements of the national standard. 1 meter away from the GE container is less ...
