Under pressure: From the cylinder to the cockpit
“We connect smart sensors to the gas equipment that is attached to the cylinders. This can be done quickly and easily,” explains Linde Global Project Manager Chris Cowles. The sensors can be fitted to a pressure regulator or a manifold, or even to single cylinders if they have a pressure port. The sensors then monitor the pressure within the cylinders and transmit the information to a cloud platform via a repeater. This data is made available to Linde customers in a web-based end-user interface, known as the cockpit.
“The gas content of cylinders is always communicated as a percentage,” says Cowles. When the percentage reaches a certain level, customers can receive a notification via email or SMS. “The level at which this happens can be set by the user,” he adds.
And it doesn’t have to end with a notification. DIGIGAS® in fact comes in three different packages. While DIGIGAS® Notify keeps customers in the loop when it comes to gas-content levels, the second service level goes one step further. DIGIGAS® Order automatically reorders cylinders – thus removing another manual step in the process.
The third option is known as DIGIGAS® Total. As the name suggests, this is the full-service option for Linde customers. Here, the connection of new cylinders and the collection of old ones is also taken care of.
“Each service offer is designed to match specific market requirements,” explains Christine Kandziora, Commercialisation Director Spec Gases at Linde. DIGIGAS® can be applied to institutions with stationary systems on site, such as research labs, or larger companies that provide gas to individuals such as welders. In the second case, a centralised system ensures that everyone has access to the information as and when they need it, rather than relying on communication between the different people involved.
“While not sector specific, DIGIGAS® is particularly well-suited to manufacturing, research and the automotive industry,” says Kandziora.
