Operations Technology Development (OTD)

The shutoff valve is attached to the service line with the termination fitting attaches to the riser. An inner and outer PE line systems are attached to the valve and the termination fitting. The gas flows in the inner system at normal operating conditions. If leak occurs, gas is released which closes the valve. The system is designed to detect small flow and is compatible with Internet-of-Things (IoT) to notify utilities of the status of flow.

The technology addresses the need to protect outdoor gas meter systems with an automatic gas shutoff when subjected to physical damage from outside forces. The damage to meter sets from outside forces includes vehicular damage and extreme weather conditions such as heavy snow and ice.

Increased Safety - The intelligent shutoff device is installed in commercial and small industrial service lines to detect leaks and shutoff gas flow when the lines are subjected to third-party excavators and vehicular damage.
