Recently, Team 4 of the Metrology Department at Jingmen Petrochemical Inspection and Metrology Center successfully resolved the crisis related to measurement errors in liquefied gas at the time of shipment, thereby effectively protecting the legitimate rights and interests of both the enterprise and its customers. Team 4 for metering is primarily responsible for the metering of liquefied gas at the point of production, and one of its key tasks is to compare the measurement results obtained from flow meters. In accordance with the company’s requirements for measurement management, it is necessary to weigh the empty and loaded vehicles using high-precision truck scales before and after loading liquefied gas. The data from these truck scales is then compared with that from the flow meters, to ensure that the error in the measured flow rate remains within specified limits, thereby protecting the economic interests of both the company and its customers. At 17:00 on March 10, Shift 4 for metering detected an anomaly during the metering comparison at the liquefied gas production site: the measurement values from 4 of the 8 loading cranes exceeded the internal control standards. It was the peak period for liquefied gas production, and loading tasks were urgent. “The pressure is indeed high; it’s necessary to ensure production efficiency while also adhering to the strict measurement standards. ”Class leader Wang Ping said. According to technical analysts, the recent temperature difference between day and night exceeding 15 degrees Celsius causes thermal expansion and contraction in metal flowmeters, which is the main reason for measurement errors. In the face of an emergency, the team immediately activated the emergency response plan. Carry out a second verification strictly in accordance with the procedures, coordinate with the maintenance team to conduct calibration at the same time, and maintain close communication with the storage and transportation department as well as the freight drivers. After 3 hours of continuous effort, the results of the third comparison showed that all error values for the crane positions returned to the acceptable range of ±0.2%. At this moment, the team members who had been on duty continuously for 10 hours smiled. \"Accurate measurement is the lifeline of a company.\" ”Wang Ping said that the professional competence of the advanced team was demonstrated during this emergency response.
