影响差压式流量检测系统测量误差的因素

Factors that Influence Measurement Errors of the Differential Pressure Type Flow Measuring System

差压式流量检测系统在实际使用过程中,由于设计工况参数偏离实际工况参数会导致测量数据出现比较大的误差,而此误差易被维护人员忽视。本文讨论了常见的几种影响因素及其修正公式。

During the using of the differential pressure type flow measuring system, the measurement data have errors, because the design working parameters deviate the actual parameters. However, the service engineers always neglect these errors. Many common influence factors and modifier formulas are discussed in the paper.
