In the power generation industry, reliability and efficiency are critical. This case study examines a Combined Cycle Power Plant (CCPP) that supplies electricity to approximately two million households daily with a total production capacity of 1,410 megawatts. The plant operates with three Combined Cycle Units (CCUs), each comprising a steam generator with heat recovery, a gas turbine, a steam turbine, and a generator. To ensure seamless operation, the plant integrated SIL Certified AMETEK LMS Magnetrol branded Guided Wave Radar (GWR) transmitters as a key component of their level measurement strategy.
