摘　　要：城镇燃气担负着天然气产业终端居民用气、工商业用气的供气业务,受季节温度、居民生活规律、工厂生产周期等影响比较大,用气存在很大的不均匀性和周期性,对燃气计量器具的计量准确性具有很高的要求,流量计选型不当直接造成城镇燃气供销输差,造成经营损失。本文通过对城镇燃气常用流量计进行介绍和使用特点进行分析,对燃气企业计量仪表选型和生产经营管理起到很大的借鉴和提升作用。Town gas is responsible for the gas supply business of residential gas and industrial and commercial gas in the natural gas industry.It is greatly affected by seasonal temperature,residents’living rules,factory production cycle,etc.,and the gas consumption has great unevenness and periodicity,which has high requirements for the measurement accuracy of gas measuring instruments.Improper flowmeter selection directly leads to input difference of supply and marketing of town gas,resulting in business losses.In this paper,the commonly used flow meters for town gas are introduced and their use characteristics are analyzed,which can be used for reference and promotion for the selection of metering instruments and the production,operation and management of gas enterprises.
