Abstract
A meter for measuring the flow rate of fuel in a fuel dispenser comprises a housing with an axial bore extending therethrough and defining an inlet and an outlet. A flow indicating mechanism comprising one or more rotatable components are mounted in the axial bore of the housing and configured to rotate as fuel flows from the inlet to the outlet, wherein each rotation indicates fuel flow. A pulse generating device senses rotation of the rotatable components and generates an output signal indicative of the fuel flow. Finally, a vapor generating device is configured to generate vapor bubbles that flow through the flow indicating mechanism.
