When there is no change in register when liquid propane is flowing the first meter component to check is the ______ for movement. If movement is seen, the ______ must be repaired or replaced.

• A. Drive Train, Register
• B. Meter, Counter
• C. Valve, Gauge
• D. Display, Panel

Answer: (A)

When a meter readout doesn’t change while propane is flowing, the first thing to check is the drive train—the moving link that translates the flow into motion that the display can count. If you observe movement in that drive train, it shows the flow is reaching the mechanism, so the fault lies with the part that records or displays the movement. In that case, the register must be repaired or replaced to restore an accurate readout.
