影响电磁流量计使用精度的相关因素介绍说明
At present, whether it is industrial or agricultural water use scheduling, the data obtained by electromagnetic flowmeter measurement should be used as a reference to further develop a feasible water planning utilization mechanism. Flow meters are commonly used tools in modern industrial surveys, allowing professionals to perform accurate operations by following the standard. However, the electromagnetic flowmeter is also facing different stability during the use phase, and the low accuracy index is a common phenomenon, which will affect the final water distribution efficiency. According to the author's work experience, the factors affecting the accuracy of electromagnetic flowmeters include: personnel factors, instrument factors, data factors, etc.
1. Instrument factor. With the deepening development of industrial science and technology research, flow meter product types are more styles. From the perspective of flow meter division, flow meters can be divided into rotameters, throttling flowmeters, slit flowmeters, volumetric flowmeters, and electromagnetics. Flow meters, ultrasonic flow meters, and helium. If divided by medium, there are mainly liquid flow meters and gas flow meters. The scope of use of each type of flowmeter is different. If the instrument product is selected that does not meet the actual application requirements, the standard coefficient of the obtained data will be reduced after the overall measurement. The uncertainty of the flowmeter accuracy standard greatly affects the accuracy of the instrument operation. Sex.
2, personnel factors. As a professional instrument in industrial production, environmental protection, energy metering, etc., the flowmeter uses professional standards for the operation process, and the measurement personnel's operation process is not standardized, unprofessional, and not uniform, which is the subjective method of reducing the accuracy of flow calculation data. factor. Taking water conservancy measurement as an example, the surveying personnel set operational errors such as instrument position and measurement range, misleading the measurement and control process of the meter, and the final data is very different from the actual measurement index. In addition, the personnel are familiar with the instrument and blindly manipulated, which also reduces the accuracy of the meter.
