摘要

描述了如何分析涡轮流量计中传感器的无条件信号以提供仪器的特征。这个签名不仅是涡轮流量计提供的习惯信息的补充，而且还表明了仪器在工艺环境中的状况。用理论模型综合了涡轮流量计在正常和异常工况下的基本信号。通过对理论信号和实际信号的分析，对理论模型进行了验证。

On monitoring the condition of turbine flowmeters

A description is given of how the unconditioned signal from the sensor in a turbine flowmeter can be analyzed to provide a signature of the instrument. This signature is not only additional to the customary information provided by a turbine flowmeter, but it also indicates the condition of the instrument within the process environment. A theoretical model is used to synthesize the basic signal expected from a turbine flowmeter operating under normal and abnormal conditions. The results obtained by analyzing theoretical and practical signals are compared to validate the theoretical model.<>
