机译:气体流量计/计数器的测试设置

摘要

FIELD: measurement equipment.;SUBSTANCE: setup includes pipeline, shutoff valves, compressor for injection of consumed medium (1), flexible bag (3), inlet test line (4), test manifold (5), outlet test line (7), filter (8), reference flowmeter (9), flow rate setting device (10), absolute pressure sensor (11), temperature sensor (12) and differential pressure sensor (13). Flexible bag (3) is covered with a plate intended for weights loaded onto it with certain mass. Compressor outlet (1) is connected to flexible bag (3) loaded with the specified mass. Outlet of flexible bag (3) is connected to inlet test line (4) that is connected to test manifold (5). Test manifold (5) includes test sections (6) intended for installation of tested gas flowmeters/counters. Test manifold (5) is connected to outlet test line (7) that is connected through filter (8) to reference flowmeter (9). Outlet of reference flowmeter (9) is connected to flow rate setting device (10).;EFFECT: providing strict pressure constancy of consumed medium at complete elimination of its pulsations occurring at operation of compressor; possibility of setting a big number of flow metre points at tests and calibration of flowmeters/counters; automation of calibration process and drawing up a calibration record; simplifying the design of the setup and improving its operating reliability; providing the filtration of consumed medium.;2 cl, 1 dwg
