Question:

When measuring steam flow with a flowmeter, why do you need temperature or pressure compensation?

When measuring steam flow with a flowmeter, why do you need temperature or pressure compensation?

Answer:

As for the water vapor compensation, if the water vapor is saturated steam to pressure or temperature compensation (compensation of temperature and pressure compensation of the a). If it is for superheated steam temperature and pressure compensation (compensation of temperature and pressure compensation at the same time).
Of course, there are some instruments that do not need to be divided into water, steam is saturated steam or superheated steam, because they are equipped with measuring temperature and pressure besides the device that measures the flow
Note that in the classification of water steam, saturated steam and superheated steam, do not be mistaken, because the density is higher than that of saturated steam superheated steam, in selecting and setting instrument must pay attention to in this place. Once the mistake, will cause serious economic losses.
According to the principle of measurement, our flowmeter can only measure the volume of fluid flowing in the current condition, so this situation is not practical for usWhen we actually use, is to measure fluid flow number and steam quality. Under different pressure and temperature, the density varies greatly, so you have to measure the pressure and temperature in the measurement of steam flow number volume at the same time. Only time can understand the steam density, accurate measurement of steam quality.The so-called compensation is based on the fluid temperature and pressure data to calculate the density of the fluid, so as to calculate the fluid volume according to the calculation of fluid quality
