1. Regarding how to set up vortex flowmeters and secondary meters, these questions are relatively simple for those familiar with instruments. Let me briefly explain it to you. If there is anything else you dont understand, please feel free to ask me again. I specialize in researching various flow meters, and friends who need to buy meters can also come to me. 1. Except for those with density compensation function, the measurement results of vortex flowmeters are usually in volume units, such as m3/h. The flow meter with automatic density compensation function calculates the density automatically and is not manually set. The vertical compensation of steam density is usually divided into saturated steam temperature compensation, saturated steam pressure compensation, and superheated steam temperature and pressure compensation. Manufacturers who claim to directly output mass flow rate either input density values as fixed numerical values into the flowmeter or mix density values into instrument coefficients, which are not truly reliable actual values. For example, if the range of the vortex flowmeter is 7100m ³/h and 3T/h, the setting of the secondary meter should also correspond to this. This helps ensure the accuracy and consistency of measurement results. For your specific situation, if the vortex flowmeter has already been purchased, its compensation function cannot be added. At this point, you need to add a compensation device separately. According to your steam temperature of 210 ℃ and pressure of 0.5Mpa (gauge pressure), it belongs to superheated steam. In order to obtain accurate mass flow rate, dual compensation of temperature and pressure is required. Therefore, it is recommended to install thermistor and pressure transmitter, and introduce the temperature, pressure, and flow signals into the secondary meter (which must have temperature and pressure compensation function) for compensation calculation, in order to obtain accurate steam mass flow rate. PS: If you dont want to add these devices and want to calculate the density based on your own measured steam temperature and pressure, its also very easy. Multiply the density value calculated by yourself by the range value (volume) of the vortex flowmeter, and use the result as the range of the secondary meter for setting. For example, if the range of the vortex flowmeter is 0-1000m3/h and the steam density lookup table is 3.18kg/m3, then the range of the secondary meter is set to 3180, in kg/h, representing the mass flow rate. PS: The steam temperature you mentioned is 210 and the pressure is 0.5Mpa. If 0.5Mpa refers to the gauge pressure, then the steam density should be 2.77kg/m3; If referring to absolute pressure, then the vapor density is approximately 2.30 kg/m3. Regarding the 2.2kg/m3 you mentioned, I am unable to determine the calculation method for your limb grinding. Usually, you should refer to the superheated steam density table and follow national standards. I hope you understand! 1. Yes, this problem can be solved. 2. The issue with setting the secondary table may be due to improper settings. The secondary meter settings may vary from manufacturer to manufacturer, and it is recommended to adjust them according to the explanations provided by the manufacturer before modifying the settings. Based on the pressure and temperature you provided, as well as the flow range of the DN50 vortex flowmeter, it is indeed difficult to achieve an upper limit of 1T/H. Your statement
