Error analysis and control strategy in liquid flow measurement verification

摘要

液体流量计量广泛应用于能源、化工、水利、环保等领域，其准确性直接影响贸易结算、过程控制和安全运行。检定作为确保计量器具量值准确的关键环节，在实际操作中常受多种因素影响，导致测量结果产生偏差。本文系统分析了液体流量计量检定过程中的主要误差来源，包括设备系统误差、环境影响误差、操作人为误差和介质特性变化引起的误差。针对不同类型的误差，提出了优化设备选型与校准、改善环境条件、规范操作流程、建立质量控制体系等相应控制策略，为提高液体流量计量检定准确性提供了理论依据和实践指导。

Abstract

Liquid flow measurement is extensively applied in energy, chemical, water resources, and environmental protection sectors, where its accuracy directly impacts trade settlements, process control, and operational safety. As a critical step in ensuring measurement instrument accuracy, verification is often affected by various factors in practice, leading to measurement deviations. This paper systematically analyzes the primary error sources in liquid flow measurement verification, including equipment system errors, environmental influence errors, operational human errors, and errors caused by medium characteristic variations. For different error types, corresponding control strategies are proposed, such as optimizing equipment selection and calibration, improving environmental conditions, standardizing operational procedures, and establishing quality control systems. These strategies provide both theoretical foundations and practical guidance for enhancing the accuracy of liquid flow measurement verification.
