Abstract
It is well known that the wetness of steam flow sometimes causes measurement errors of the steam flow meter. However, it is difficult to clarify a particular error quantitatively in actual plants and factories, and thus far, there has been no established method for estimating the error caused by the wetness of steam flow. Therefore, wet steam flow rate measurement experiments were conducted to clarify the measurement error caused by the wetness of steam flow in a plant and a factory. We have conducted 3 types of the steam flow meter, orifice flow meter, vortex flow meter and ultrasonic flow meter. In this paper, we introduce the correlation between the measurement error and the flow condition and correction methods.
