🔍 Key Concepts

• Distilled water make-up feed tank function in a steam plant or condenser system • How a remote level indicator might give false high or false low readings • Relationship between tank level, condenser vacuum, and contamination risks

💭 Think About

• Think about what could happen if the indicated level is higher than the actual level, and operators rely on that incorrect reading. • Consider how the physical connection points (overflow lines, make-up lines, and connections to other tanks) relate to tank level and system pressure. • Ask yourself: if the level indicator is wrong, which of the listed consequences are realistically possible in this type of system?

✅ Before You Answer

• Verify how loss of vacuum in a condenser can occur when water levels reach certain piping connections. • Check whether an incorrect high level reading could influence condenser absolute pressure by affecting circulation or make-up water control. • Confirm whether any overflow or cross-connection to potable water tanks exists in typical designs and what that would imply for contamination risk.
