District governors supply gas to homes via the low pressure (LP) distribution mains network. This network still has a large percentage of old cast iron mains that are prone to leakage in proportion to the pressure within the main. The installation of clock control to district governors allows the pressure in the LP mains system to be reduced therefore reducing the amount of leakage from cast iron mains which in turn is costly to networks and disruptive to customers and stakeholders. Clocks have been used for many years but recently the existing clocks have become obsolete as they are no longer supported by manufacturers. There are also networks within NGN that work on fixed pressure and do not have clock control which means the average mains system pressure is higher leading to increased leakage.

Objectives

To produce a functioning and cost effective district governor clock that can be operated remotely via SMS text.
