用联通器原理进行汽包水位测量装置冷态标定

A Cold State Calibration Method of Drum Water Level Measuring Device Based on Connected Device Principle

提出了一种简单易行的、适用于各种汽包水位测量系统的冷态标定新方法,为减少汽包水位的测量误差,以及该测量方法与其它测量方法之间的关系给出了明确的描述。提出了视在量程和视在量程上限的概念,使汽包水位测量的概念更加清晰、准确。此方法也可用于其他水位测量装置的冷态标定。

This paper puts forward a new cold state calibration method of drum water level measurement system ,which is simple and suitable for all kinds of measuring devices. Clearly describes the way to reduce error of the drum water level measurement and differences between this method and the others. Proposes the concept of Apparent Range （AR） and upper limit of Apparent Range, which makes the concept of drum water level measurement more clear and accurate.
