Steam measurement with or without temperature and pressure compensation instructions

First of all: the mass flow of steam has a great correlation with temperature and pressure, because the density of steam has a great correlation with the pressure and temperature of steam. The same volume of steam has different masses due to different pressures. For example, when saturated steam P=6 kg, ρ=3.111 kg/m3 P=7 kg, ρ=3.6 kg/m3. The same volume, the quality is 14% difference
Secondly: if there is temperature and pressure compensation, the intelligent totalizer equipped with the flowmeter is measured with steam temperature and pressure change, which is very accurate.
If there is no temperature and pressure compensation, the flowmeter can only be calculated according to the common data provided by the user. The error here is consistent with the “user-supplied common data and actual data error” or positive correlation.
For the measurement of steam medium, our company generally recommends customers to use the vortex street with temperature and pressure compensation function. The reason is: vortex flowmeter is a speed flowmeter. The most original flow rate measured is the volume flow, which is an hour. How many cubic meters of steam, and in actual work, people are accustomed to the flow of steam in mass units, usually say how many tons or kilograms of an hour. The volume is converted into mass flow. The most critical value in the middle is density. The density of steam is linear with pressure. The pressure is large and the pressure is small. On the contrary, the pressure is small and the density is small. The factory setting without temperature and pressure compensation function is set. The density value of the time is based on the pressure setting provided by the customer. Once set, regardless of the pressure of the current pipeline, our meter is displayed according to the set value. If the current pipe pressure is less than the set pressure, the cumulative flow displayed on the screen is more than the actual one, and vice versa.
If the pressure with temperature and pressure compensation function is used, the chip inside the calculator can automatically identify the pressure of the steam in the current pipeline, and automatically transfer the corresponding density value to the totalizer for conversion, so that in addition to the basic error of the meter In addition, the displayed traffic is the actual flow of media in the pipe.
