PowerSub
A stand-alone power generator for gas networks with no moving parts. Based on NASA power harvesting technology, the PowerSub can be used to generate power at pressure reduction locations in gas piping systems. The generated power is used to measure the upstream and downstream gas pressure and temperature at a rate of one sample every second and transfer the processed data in six-minute intervals through GSM communications. Additional power is available for control. The PowerSub has been designed for pressure reducing installations in the UK natural gas networks, to address an industry driven desire for more network data in ATEX rated zones. The standard telemetry uses approximately 20% of the total power produced leaving 80% of the power available for additional control and telemetry.
