Multiple Choice

A liquid meter will over register any time there is vapor in the ________.

Explanation:
The measuring chamber is where the meter actually counts the liquid being delivered. If vapor gets into that chamber, the gas can be present during the metering cycles, confusing the displacement measurement. Since the meter assumes only liquid is filling and moving through the chamber, any vapor presence causes the device to register more liquid than is truly flowing—i.e., it over-registers. The other parts mentioned (hose line, tank outlet, gauge assembly) are not where the metering displacement happens, so vapor there doesn’t directly cause the same over-reading.
