With an estimated 30 % of the existing process industry workforce expected to retire over the next five years, taking a great deal of operating and commissioning knowledge and experience with them, it is becoming ever more challenging for the remaining, less-experienced workforce to install and maintain constantly evolving technology.

It is essential for devices involved in critical measurements to be correctly installed and commissioned, as incorrectly commissioned devices can give inaccurate or unreliable readings. This could then contribute to a potential safety incident, such as an overfill or spill. Even if an error is identified before an incident takes place, the device would still need to be reinstalled, which would involve placing workers in a hazardous environment again. The latest generation of radars and switches have therefore been designed to simplify installation and operator tasks, so that even less-experienced workers will be able to perform them easily, therefore minimising human errors.

With close end-user collaboration, new generation radars have been systematically designed to provide an easy user experience at every step, from product specification to installation, commissioning, proof-testing, operation and maintenance. Pictorial product documentation is available where and when it’s needed, and the highly graphical software interface makes configuration straightforward and the instrument easy to understand.

Ease-of-use throughout installation, commissioning and operation is also integral to the design of new generation vibrating fork level switches. The fact that these devices don’t contain any moving parts makes them easy to install and maintain. By minimising the amount of time that maintenance teams might need to spend working on them in potentially dangerous areas, they also increase safety. Easy integration into Hart 5 and Hart 7 systems allows them to take advantage of the latest Hart communications functionality. Local and remote configuration can be enabled via integral push buttons and LCD, and data can be presented on the operator’s interface in a clear and easy-to-understand way, reducing the potential for human error to affect safety.
