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 typically used for high-precision measurement and calibration work. Secondary standard instrument: Its accuracy level includes 0.

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 tech

nique 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 tube float flowmeter: The accuracy level is usually 2.5. Electromagnetic flowmeter: The accuracy level is usually 0.5.

III. Precautions: Accuracy level is one of the important indicators for evaluating the performance of flow meters, but it is not the only indicator.

. When choosing a flowmeter, other factors such as measurement range, fluid characteristics, working environment, etc. need to be considered. The classification and calculation methods of accuracy levels may vary depending on different countries or industry standards. In practical applications, relevant standards or specifications should be referred to for selection and calculation.

2. Could anyone please explain in detail the starting flow rate of the flowmeter, the more detailed the better.

The vortex flowmeter is a flow measurement instrument designed based on the Karman vortex principle, suitable for measuring the volumetric flow rate of gases, liquids, and vapors, as well as the volumetric flow rate or mass flow rate under standard conditions.. Its measuring medium includes but is not limited to gas, liquid, and vapor, with various connection methods including flange clamping, flange, and insertion,
