The accuracy of measuring instruments directly impacts the quality of a company’s production processes and final products. In manufacturing enterprises, managing these instruments effectively is crucial to ensuring quality control. However, given the sheer volume of measuring instruments—sometimes numbering in the hundreds or thousands—their calibration, maintenance, and management pose significant challenges, especially in medium-to-large-scale manufacturing […]

In Distributed Control Systems (DCS) and industrial automation, setting up Low-Low (LL) and High-High (HH) alarms is crucial for providing comprehensive safety protection and operational guidance. While Low (L) and High (H) alarms are already in place to signal when process parameters deviate from their normal ranges, LL and HH alarms are introduced to handle

1. Equipment Selection and Installation 1.1. Inadequate Adaptation to Environment: Choosing equipment unsuitable for the working environment, such as neglecting factors like gases, dust, or humidity. Preventive Measure: Conduct a thorough environmental analysis and select equipment certified for the specific gas group and temperature class. 1.2. Improper Installation Location: Installing equipment in areas with vibration,

Introduction Gas flow standard devices are essential instruments used for calibrating and measuring gas flow in various industrial and scientific applications. These devices ensure the accuracy and traceability of gas flow measurements, thereby improving efficiency, safety, and compliance in sectors such as metrology, energy, environmental monitoring, and manufacturing. This article explores the types, working principles,

1. Quick Fault Location & Visual Identification of Abnormalities Instrument curves provide a clear, visual representation of how the measurement values change over time or with other variables. Under normal conditions, these curves should exhibit a relatively stable trend or follow a predictable pattern. However, when a fault occurs, the curve will often display abnormalities,

Introduction A liquid flow standard device is a precision instrument used to calibrate, verify, and evaluate the performance of liquid flow meters. These devices ensure accuracy in flow measurement across various industries, including petroleum, pharmaceuticals, water management, and chemical processing. By providing traceability to national and international standards, liquid flow standard devices are critical for
