In the grand theater of industrial production, the differential pressure transmitter stands as an indispensable “unsung hero” in numerous industrial processes, thanks to its precise measurement and reliable performance.

In a large petrochemical company’s refining facility, the monitoring of various oil products’ flow rates and liquid levels is crucial. In the oil product storage tank area, differential pressure transmitters are used to measure the liquid level height. By measuring the pressure difference between the bottom and the top of the tank and combining it with parameters such as the density of the oil product, the liquid level inside the tank can be calculated accurately. This plays a vital role in the reasonable arrangement of oil product storage and transportation, helping to avoid dangerous situations such as overflow or emptying. In the pipeline transportation system, differential pressure transmitters are used to measure the pressure difference between the two ends of the pipeline, thereby calculating the flow rate of the oil product. On a crude oil transportation pipeline, a high-precision differential pressure transmitter is installed to monitor the flow rate changes in real-time. In the event of abnormal fluctuations in flow, the system can issue an alert promptly, allowing staff to quickly troubleshoot issues, such as potential pipeline leaks or valve failures, thus ensuring the safety and efficiency of oil product transportation.

Since the adoption of differential pressure transmitters for liquid level and flow rate monitoring, the incidence of oil product storage and transportation accidents at the company has significantly decreased. At the same time, through precise flow measurement, the company has been able to arrange production plans more reasonably, improving production efficiency and reducing production costs.
