Monitoring of boiler saturated steam and superheated steam parameters

When water is heated, its molecules vaporize and separate from the liquid. If there is a limitation in the upper space (pressure generated by that space), the number of vaporized water molecules in that space continues to increase, and the pressure usually rises from zero to a certain value. After some time, the density of vaporized water molecules in that space reaches a stable level, neither increasing nor decreasing; this state is known as saturation. It’s like there’s a group of people in a room; although some come in and go out, the number remains more or less the same. And based on the properties of steam, it is assumed that when such a saturation value is reached, there is a linear relationship between the temperature and pressure in that space. So when we measure the flow rate, we only need to compensate for one of the values. If saturated steam has its temperature increased or pressure applied to it, in other words, if the temperature-pressure relationship that defines a saturated state is disrupted, it becomes superheated steam – it’s beyond the saturated state, haha, too much. To determine to what extent this occurs, it is necessary to measure both temperature and pressure, and then use these values as a compensation factor when calculating the flow rate.
