How is the accuracy of flow meters classified?
You can check the relevant calibration regulations based on the type of flow meter you have. For example, for vortex street flow meters, the common accuracy levels on the market are 1.0 and 1.5, 0.2 and 0.5 for electromagnetic flow meters, 1.0 or 1.5 for differential pressure flow meters, 0.1 and 0.15 for Coriolis mass flow meters, 0.2 and 0.5 for liquid turbines, and 1.0 for gas turbines. The above are the commonly used accuracy levels produced by most flow meter manufacturers.
2. Classification of flow meter measurement accuracy levels.
Classification of flow meter measurement accuracy levels is used to measure the measurement accuracy level of flow meters.The standard for the range of error between the measurement results and the true values. The higher the accuracy level, the smaller the error range, and the more accurate the measurement results. The accuracy levels of flow meters are divided as follows:
I. Overview of accuracy levels Level 1 standard instruments: accuracy of 0.00
5, 0.0
2, 0.05. These instruments are typically used for high-precision measurement and calibration. Secondary standard instrument: accuracy of 0.
1. 0.
2. 0.3
5. 0.5. These instruments are widely used in industrial measurement and calibration. General industrial instruments: Accuracy is
1.
5. 2.
5. 4.0. These instruments are suitable for industrial applications that do not require high measurement accuracy. Scientific experimental instruments: accuracy level above 0.05. These instruments are typically used for scientific experiments and research that require high-precision measurements. Electrical instruments:

2. Specific Level and Application: Level 0.1: The highest accuracy level, with an error range within 0.1% of the flow rate.
. Suitable for laboratory testing, accurate flow control, and research that require extremely high precision. Level 0.5: The maximum allowable error is 0.5% of the flow measurement value. Suitable for applications that require high accuracy in flow measurement, such as chemical, pharmaceutical, and food processing industries, where accurate control of flow is crucial. Level 1: The maximum allowable error is 1% of the flow measurement value. Suitable for situations where high precision is required for measuring the accuracy of convective ear grinding, but low precision is required for 0.5 level accuracy, such as some medium precision industrial measurements. Level 1.5: The maximum allowable error is 1.5% of the flow measurement value. Suitable for occasions that require moderate accuracy, such as industrial applications that have certain requirements for flow measurement accuracy but do not require extremely high accuracy. Level 2 and Level 4.0: The maximum allowable errors are 2% and 4% of the flow measurement value, respectively. Suitable for applications that require lower precision, such as industrial process control that does not require high precision for flow measurement.III. Factors Affecting Accuracy Level The accuracy level of a flowmeter is affected by multiple factors, including but not limited to: flowmeter type: Different types of flowmeters (such as electromagnetic flowmeters, vortex flowmeters, ultrasonic flowmeters, etc.) ha
