摘要：NOVELTY - The system has an air compressor and an air storage tank that are connected with a front pneuma source generating device, a mounting nozzle flow meter, a ultrasonic vortex shedding flow meter and a three-way pipeline. The air storage tank and a rear mounting three-measuring table are connected with the three-way pipeline for measuring a standard area of the three-measuring table. An electric sleeve regulating valve, a decompression valve and a temperature and pressure compensation device are connected together. A main controller is connected with a PC by a RS485 bus. USE - Multi-path pipeline high-speed gas flow calibration system for use in a laboratory. ADVANTAGE - The system has strong capacity, and controls fluid generating rate by utilizing a process control system and improves reliability of a pneuma source. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a multi-path pipeline high-speed gas flow calibration method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a multi-path pipeline high-speed gas flow calibration system.
