What factors affect the measurement accuracy of the vortex flowmeter

Abstract: What factors affect the measurement accuracy of vortex flowmeters are provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Most of the users we are facing now use vortex flowmeters to measure more steam flow. Today, we will focus on saturated steam to analyze with you what factors affect the accuracy of steam vortex flowmeters. Problem Analysis and Solutions: . More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the measurement accuracy of the vortex flowmeter. Most of the users we are facing now use vortex flowmeters to measure more steam flow. Today, we will focus on saturated steam to analyze with you what factors affect the accuracy of steam vortex flowmeters. Problem analysis and solution: 1. Steam is dry humidity analysis: In the article 'Whether the moisture in steam affects the accuracy of vortex flowmeter', we have introduced that steam cannot contain too high moisture, and the dryness of steam is in the 85% or less. Solution: When the steam humidity is higher than 85%, a humidity transmitter needs to be installed at 7D-8D at the outlet of the flowmeter. 2. Analysis of excessive pressure change of saturated steam: The pressure change in industrial sites is relatively common, and the pressure change directly leads to the density of saturated steam. When the pressure change value is higher than the calibration value, it will directly affect the flow rate The value is high or low; solution: Because the density of saturated steam is in one-to-one correspondence with pressure and temperature, we can correct the density according to the change of pressure, and can use the table look-up compensation method to correct it. 3. The vibration of the instrument installation pipeline is relatively high. Large analysis: The pipeline is not reinforced during installation. When the vibration is large, the flow value will be high. Solution: Triangle reinforcement of the pipeline. 4. The outlet of the steam vortex flowmeter leads to the atmosphere. Analysis: When the outlet of the flowmeter leads to In the atmosphere, the pressure difference between the front and rear will be too large, and it is easy to reach the upper limit of the flow rate of the flowmeter; solution: the flow rate of saturated steam needs to be strictly controlled so that it is lower than the upper limit of the flow rate of the flowmeter, or a rectifier is installed on the side 5, steam vortex street Analysis of the incorrect analysis of the front and rear straight pipe sections installed on the flowmeter: When the front and rear straight pipe sections of the flowmeter do not meet the requirements, it can be concluded from the working principle of the vortex flowmeter that the necessary conditions for vortex formation cannot be achieved when the distance does not meet the requirements. Solution: The distance between the front and rear straight pipe sections of the steam vortex flowmeter must be installed in strict accordance with the requirements. Summary: After the user purchases the vortex flowmeter, the engineers of Shanghai Baiqi Instrument and Instruments strongly mind during the installation process. Read the instructions carefully before installation to avoid installation. The occurrence of unnecessary factors after work The above is the entire content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'What Factors Affect the Measurement Accuracy of Vortex Flow Meters'
