| 依据JJG 1033-2007《电磁流量计》检定规程中附录A型式评价大纲的要求，流量计量仪表应在环境温湿度发生变化的条件下，对其计量性能进行考核。为满足型式评价大纲的要求，开发了一套“流量计量仪表环境试验在线检测装置”。该装置可将流量管路、被测仪表直接接入到环境试验装置内，通过改变温湿度设定参数，对被测仪表计量性能进行考核。专家验收表明：该装置完全能够满足对流量计量仪表在温湿度环境条件变化的情况下，进行在线计量检测。 |
| 英文摘要: |
| The metrological performance of flow meter should be tested under the condition of ambient temperature and humidity changes according to appendix A type evaluation outline of JJG 1033-2007 "Electromagnetic Flowmeter" verification procedures. In order to meet the requirements of the type of evaluation outline, an "environmental test on-line detection device based on flow metrological instrument" is developed. The pipe and the meter can be directly connected to this device. The metrological performance of the meter can be assessed and the environment’s temperature and humidity can be controlled at the same time. Experts have identified that the device can fully meet the requirement that metrological performance of flow meter can be tested under the condition of ambient temperature and humidity changes. |
