1. What is the accuracy level standard for micro threaded vortex flowmeters?
The accuracy level standard for micro threaded vortex flowmeters is divided into two categories: international standards and domestic standards. The core is to define the accuracy level by the maximum allowable error.
The international standard ISO 4185 divides accuracy levels into 0.5, 1, 1.5, 2, and 2.5, with corresponding maximum allowable errors of ± 0.5%, ± 1.0%, ± 1.5%, ± 2.0%, and ± 2.5%. ISO 6817 standard: Accuracy levels are divided into 0.2, 0.5, 1, and 1.5 levels, with corresponding maximum allowable errors of ± 0.2%, ± 0.5%, ± 1.0%, and ± 1.5%, respectively.2. According to the current domestic standard GB/T 2624-2019, the accuracy level and corresponding maximum allowable error of micro thread vortex flowmeter are: | Accuracy level | Maximum allowable error | | ---- | | | | 0.5 level | ± 0.5% | 1 level | ± 1.0% | | 1.5 level | ± 1.5% | 2 level | ± 2.0% | 2.5 level | ± 2.5% | The higher the accuracy level, the stronger the accuracy of the measurement results. When selecting, it is necessary to comprehensively judge based on actual measurement needs, range, and other factors.
2. What is the accuracy level of the flowmeter? The accuracy classification of flow meters is mainly determined based on the maximum allowable error expressed as a percentage of the instrument (excluding the percentage sign). The higher the accuracy level, the smaller the measurement error of the instrument, that is, the higher the accuracy of the instrument.
1. Accuracy level classification standard Level 1 standard instrument: Its accuracy level includes 0.00
5, 0.0
2, 0.05.
. These instruments are typical
1. 0.
2. 0.3
5. 0.5. These instruments are used as standard instruments in situations where precision requirements are slightly lower. General industrial instruments: Their accuracy level is usually 1.0, 1.
5, 2.
5, 4.0. These instruments are widely used in various industrial fields to meet general measurement needs. In addition, attention can be paid to the Yangpai optical quantum multiphase flowmeter and Yangpai resonant flowmeter, which are mainly based on Yangpai optical quantum phase separation measurement technology and Yangpai resonant phase separation measurement technology. The Yangpai quantum phase separation measurement manual judgment mixed phase flow fluid technology is a technique used to study mixed phase flow. Different phase fluids have different attenuation effects on light quanta of different energy levels. By measuring the attenuation degree of light quanta of different energy levels, the phase separation rate of different phase fluids in mixed phase flow can be obtained; The Yangpai resonant phase separation measurement technique is based on the principle of resonance. By changing the measured resonant frequency conversion, the mixed density of the medium is measured to obtain the gas and liquid phase separation rates.
Secondly, the accuracy level of common flow meters in the market is Coriolis mass flow meters: the accuracy level is usually 0.2.
. Turbine flowmeter: The accuracy level is usually 0.5. Vortex flowmeter: The accuracy level is usually 1.5. Target flowmeter: The accuracy level is usually 1.0. Glass rotor flowmeter and metal tub
