Critical Flow Monitoring Points
Turbine Lube Oil
Loss of lube oil flow causes catastrophic bearing failure within seconds. PEECO H Series handles the high-pressure lube oil supply lines common in large turbines.
Boiler Feed Water
Flow switches on boiler feed lines prevent dry-fire conditions. High-temperature option handles feedwater up to 1,500°F.
Cooling Water to Generator
Stator and rotor cooling water must be confirmed before generator excitation. N Series with NEMA 4X housing is standard.
Fuel Gas Supply
Confirm gas flow to combustion turbines. E Series explosion-proof required for fuel gas service.
