基于LabVIEW的焓差试验室流量计现场自动校准系统

Field Automatic Calibration System of Flow Meter in Enthalpy Difference Laboratory Based on LabVIEW

设计并介绍了一种电磁流量计现场自动校准系统。详细介绍了基于Lab VIEW软件的使用质量流量计校准电磁流量计的具体实施方式,实现了自动采集校准数据、计算示值误差、生成原始记录等功能。系统即降低了人为因素引入误差的可能性,又提高了校准的工作效率。

A field automatic calibration system for electromagnetic flowmeter is designed and introduced in this paper.This paper introduces in detail the implementation method of using mass flowmeter to calibrate electromagnetic flowmeter based on LabVIEW software,and realizes the functions of automatically collecting calibration data,calculating error of indicated value and generating original records.The system not only reduces the possibility of error introduced by human factors,but also improves the efficiency of calibration.
