1. Several factors and solutions that affect the accuracy of mass flow meters
There are many factors that affect the accuracy of mass flow meters, and the following are the main factors and corresponding solutions: the accuracy of the flow meter itself: choose a high-precision mass flow meter, the calibration cycle should be appropriate, and avoid aging or damage to the flow meter. Installation position of flowmeter: Ensure that the length of the pipeline before and after the flowmeter meets the standard, and avoid factors such as pipeline bending, dead corners, and sudden changes that affect fluid flow. Fluid medium: Mass flow meters need to be calibrated based on parameters such as density, viscosity, and temperature of the medium, while also paying attention to the impact of parameters such as purity, pressure, and flow rate on measurement accuracy. Environmental factors: Temperature, humidity, air pressure, and other environmental factors can all affect the accuracy of mass flow meters and require calibration or adjustment of these factors. Fluid state: The flow state (laminar or turbulent) and flow range of the fluid can affect the accuracy of the mass flowmeter, and calibration and adjustment are required according to specific circumstances. The methods to address these factors include: selecting appropriate mass flow meters; Correctly install and use flow meters; Calibrate and adjust the fluid medium; Adjust environmental factors such as temperature, humidity, and air pressure; Calibrate and adjust according to specific situations, such as selecting appropriate fluid states, appropriate flow ranges, etc. At the same time, it is necessary to regularly maintain and calibrate the quality flow meter to ensu
2. What are the flow meters that can replace electromagnetic flow meters and have similar accuracy?
Flow meters that can replace electromagnetic flow meters and have similar accuracy mainly include vortex flow meters, turbine flow meters, Coriolis mass flow meters, and ultrasonic flow meters, which need to be selected according to the type of medium and working conditions.
1. Vortex flowmeter 1 Accuracy performance: Under conventional range ratio, the accuracy can reach ± 0.5%~± 1.0%, which is basically the same as that of conventional industrial grade electromagnetic flow meters.
2. Adaptation to alternative scenarios: It can measure clean and tidy liquids, gases, and vapors, without being limited by the conductivity of the medium, making up for the limitation of electromagnetic flow meters that can only measure conductive liquids. However, it cannot be rolled or lifted for measurements containing a large number of solid particles and highly viscous media, and it is necessary to ensure full pipe operation of the pipeline.
2. Turbine flowmeter 1 Accuracy performance: The conventional industrial grade accuracy is ± 0.2%~± 0.5%, which is comparable to the accuracy of most electromagnetic flowmeters; High precision level can reach ± 0.1%~± 0.2%, which is better than conventional electromagnetic flow meters.
2. Adaptation to alternative scenarios: only suitable for clean low viscosity single-phase liquids, such as pure water, diesel, etc., cannot adapt to media containing impurities and high viscosity, requiring full pipe installation, suitable for replacing electromagnetic flow meters to measure non-conductive clean liquids.
