摘要: 针对现有瓦斯抽放流量仪表不能对管道流量参数进行实时补偿而导致流量测量结果存在较大误差的问题，设计了一种具有动态补偿的差压式瓦斯抽放流量仪表。给出了气体温度、压力和浓度的补偿方法，介绍了该仪表的软硬件设计。现场测试结果表明，该仪表测量数据准确、稳定，满足煤矿瓦斯抽放计量的精度要求。Abstract: In view of problem of large flow measurement error caused by existing gas drainage flow meter which cannot realize real-time compensation for pipeline flow parameters, a differential pressure type gas drainage flow meter with dynamic compensation was designed. The compensation methods of gas temperature, pressure and concentration were gave, and design schemes of hardware and software of the flow meter were introduced. The field test results show that the flow meter meets accuracy requirement of coal mine gas drainage measurement with accurate and stable data.
