1. Accuracy level of mass flowmeter
The accuracy level of mass flowmeter is divided into 0.1 level, 0.2 level, 0.5 level and 1.0 level, and different levels correspond to different application scenarios that require different accuracy values. 1. Characteristics of 0.1 level mass flowmeter: It belongs to high-precision instruments, with a measurement error range of ± 0.1%. Application areas: Mainly used in scientific research experiments, aerospace fuel control, and other scenarios that require extremely high precision. For example, rocket fuel injection requires strict assurance that flow errors are within a very small range to ensure launch safety.
2. Characteristics of the 0.2 stage mass flowmeter: error range ± 0.2%, balancing high precision and cost-effectiveness.
. Application field: The core production process of the petrochemical industry, such as monomer flow control in polymerization reactions, may lead to product quality fluctuations due to insufficient accuracy. Characteristics of 0.5 level mass flow meters: Medium accuracy (± 0.5%), good stability. Application areas: Suitable for industrial water treatment and ordinary fluid transportation scenarios. For example, when monitoring the total flow of the municipal water supply system, it is necessary to meet the daily billing management needs without requiring a microgram level accuracy. The characteristics of a 1.0 level mass flow meter are that it is a basic level instrument (± 1.0% error) and has a lower cost. Application areas: Non critical scenarios such as rough metering for agricultural irrigation and auxiliary monitoring for simple production lines. When the greenhouse drip irrigation system only needs to grasp the approximate water co
2. What are the accuracy level standards for micro threaded vortex flowmeters?
The accuracy level standards for micro threaded vortex flowmeters are divided into two categories: international standards and domestic standards. The core is to define the accuracy level through 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.
