Subtracting the return flow meter reading from the supply flow meter reading on a boiler equipped with a return flow fuel oil system, determines the amount of oil __________.

🔍 Key Concepts

• Fuel oil return flow systems on boilers • Difference between total fuel supplied vs fuel actually burned at the burner • What the return line carries back to tanks or settler

💭 Think About

• When you subtract what comes back from what was sent out, are you finding what was moved in the loop, what was actually used, or what was sent back? • In a return-flow system, does all pumped fuel reach the burner flame, or only part of it? What does the surplus do? • Which quantity would logically be "supply minus return"—the fuel burned, the fuel just circulating, or the fuel the pump discharged?

✅ Before You Answer

• Be clear about what the supply flow meter measures in the system layout. • Be clear about what the return flow meter measures and where it is located (back to settler or tank). • Think: Supply – Return = ? Does that represent the fuel that actually passes through the burner or some other part of the system?
