今年4月在锦州召开全国计量工作会议,讨论了国家计量局制订的贮罐液体计量系统采用称重法计量仪表的规程讨论稿,明确了今后我国的贮罐液体计量系统应采用称重式计量仪表。采用称重法计量液体的重量,可节省密度分析、温度测量、密度修正、液位测量等多道繁琐手续,减少积累误差,从而使计量过程更为合理。目前我国生产称重式的计量仪表的厂家只有上海自动化仪表五厂,该厂生产的GGY—01型贮罐液体称量仪和GGY—01X—G型贮罐液体称量仪显示仪表配套后,能用以计量贮罐内液体的重量。由于被测液体并不和仪表直接接触,仪表可适用于很多种工业液体(如有泡沫、波动、粘性、腐蚀等等)的计量。
In April this year, a national metrology working meeting was held in Jinzhou to discuss the discussion draft of the procedure for weighing tank gauges used by the National Bureau of Weights and Measures. It was clarified that in the future, the liquid tank gauging system in our country should adopt the weighing method meter. Weighing the weight of the liquid by weighing method can save a lot of tedious procedures such as density analysis, temperature measurement, density correction and liquid level measurement to reduce the accumulation error and make the measurement process more reasonable. At present, China’s production of weighing meter manufacturers only Shanghai Automation Instrumentation Factory 5, the factory production of GGY-01 tank liquid weighing instrument and GGY-01X-G tank weighing liquid meter display instrument supporting, Can be used to measure the weight of liquid in the tank. Because the measured fluid is not in direct contact with the instrument, the instrument can be used for a variety of industrial liquids (such as foam, vibration, viscosity, corrosion, etc.) measurement.
