FMA-A2107_FMA-A2108_FMA-A2109_FMA-A2120质量流量计和控制器OMEGA

FMA-A2000系列电子质量流量计／控制器性能出众、 功能多样、设计先进、外形紧凑。FMA-A2000利用毛细管式热感技术直接测量气体的质量流量。无需进行温度、压力或平方根校正。FMA-A2300／2400系列配备LCD显示屏，并且所有型号都提供线性0 ~ 5 Vdc和 4 ~ 20 mA输出。

FMA-A2000测量0 ~ 100 SLM之间24个量程的气体质 量流量。要查看完整列表，请参阅下***页的量程表。 FMA-A2000系列与大部分非腐蚀性气体相容。建议用户对照气体相容性检查接液材料。

OMEGA的质量流量控制器利用内部电磁比例阀控制质量流量。可以通过内部电位器设定值或者通过0 ~ 5 Vdc外部源 提供指令信号
