Restraints:

• Legacy System Incompatibility and Complex Upgrades Hinder the Adoption of Advanced Differential Pressure Level Gauges

Integrating differential pressure level gauges into existing systems, particularly older or legacy infrastructures, poses significant challenges. But many industrial plants run with old control systems and equipment that are not compatible with newer, digital, or IoT-ready measures. New systems usually come with upgraded hardware, rewiring, interface changes, and more. In addition, the existing staff might not have the technical capabilities to have advanced gauges in operation or even maintain it, leading to specialized training programs that can take time, time that is normally in short supply and extremely precious to the operations.

This can also lead to difficulties in calibration processes, as new gauges might need to be recalibrated often because of inaccuracy when interfacing with legacy systems. According to the research, 58% of industrial facilities experience problems when upgrading instruments due to system fit and integration issues. Even 46% of the manufacturers state that during such a transition, more downtime occurs, which hampers overall productivity. This causes reluctance among industries, however, small and medium enterprises tend to refrain from complete implementation of advanced differential pressure level gauges because of their price versus long-term benefits.
