A remote telecom tower relies on a diesel generator with an integral day tank. The P&ID covers fuel transfer from bulk storage through filtration and a motorized fill valve into the day tank, with level, flow, and pressure transmitters feeding a field PLC for remote monitoring.
Read the decisions behind it.
Use a motorized control valve (fail open) on the day tank fill line to allow remote or automatic refilling while preventing overflow via level monitoring.
Route process signals from field transmitters to both a local flow controller and a field PLC, enabling local control and remote supervision over the same measurements.
Include an integral day tank as a separate equipment item connected to the generator, clarifying the boundary between storage and consumption.
Reusable for any small critical-power fuel system with remote monitoring requirements, such as telecom sites, off-grid backup generators, or remote pumping stations.
