简单流量测量

这种多变量发射器提高了生产率，并使energy management和环境合规性更容易。来自艾默生过程管理的Rosemount 3051SMV简化了质量和能量流量测量，提高了准确性，并通过获得专利的高级补偿技术提供了更快的更新。用户输入三个应用程序参数，工程助理软件将处理其余的。3051SMV与未补偿的差压力流相比提供了25个不同参数的全部补偿，以提高流动性能的5倍。这包括与Callendar-Van Dusen常数匹配的Joule-Thomson校正和传感器。3051SMV的更新流量测量每秒22次，因此用户可以更有效地跟踪生产，需求和过程气体，蒸汽和天然气的总使用情况。结果是更准确的计费，立即检测导致损失的异常，以及需求峰值期间产品吞吐量和质量的优化。

Rosemount 3051SMV允许用户指定最适合该应用程序的补偿水平。可以缩放以优化四个不同应用中的流量测量：

1）气体，天然气或蒸汽的全部补偿（差压力，线压和温度测量）
2) Differential and line pressure measurement for saturated steam
3）液体或饱和蒸汽的差分压力和温度测量
4）在稳定温度下液体的差异测量

3051年的可以搭配了一个Rosem smv发射机ount primary element, creating the 3051SF flowmeter. This flowmeter requires only a single pipe penetration for installation, minimizing costs in large line sizes. Annubar sensors create less blockage in the pipe than industry standard orifice plates, leading to an energy cost reduction in pumping, compression and fuel. The 3051SFC Compact Orifice flowmeter is easily installed between existing flanges with use of an integral centering ring and minimizes straight run requirements with conditioning technology. All Rosemount 3051SF flowmeters arrive fully configured, leak-tested and ready-to-install thereby reducing potential leak points and preventing fugitive emissions by up to 70 percent for better protection of the environment.
