一、概况LQZ 型蒸汽流量计作为节能管理用仪表,现已大量地用于工业生产中。该仪表具有结构紧凑,安装、使用、维护方便等优点。尤其适用于中小型规模生产装置中的蒸汽流量计量。但对蒸汽流量计的标定还未很好的解决,有的仪表未经标定或者标定装置不符合要求,致使仪表精度不能保证,造成计量不准,能源浪费。为此天津市自动化仪表厂经机械部仪表局批准建设一套蒸汽流量计标定装置,并被列为天津市一九八二年企业技改项目,委托化工部第一
I. Overview LQZ-type steam flow meter as a management instrument, is now widely used in industrial production. The instrument has a compact structure, installation, use, easy maintenance and so on. It is especially suitable for steam flow measurement in small and medium scale production plants. However, the calibration of the steam flowmeter has not been well resolved, and some instruments are not calibrated or calibrated device does not meet the requirements, resulting in instrument accuracy can not be guaranteed, resulting in measurement is not allowed, energy waste. To this end, Tianjin Automation Instrumentation Factory approved by the Department of Mechanical Instrument Bureau steam meter calibration device, and was listed in Tianjin in 1982 enterprise technological transformation projects, the first commissioned by the Ministry of Chemical Industry
