Abstract
Cooling of a meter by liquid flowing in a flow that is reverse from dispensing flow is described. A plurality of tubes is configured to transport a plurality of fluids comprising a first fluid and a second fluid. Dispense valves attached to corresponding tubes are configured to open when the first fluid is dispensed from a pump to a first outlet. Recirculation valves attached to respective tubes are configured to open when the second fluid is transported from the pump to a second outlet. A meter attached to a tube of the plurality of tubes is configured to measure properties of a fluid when the fluid flows through the tube, wherein the fluid is one of the first fluid and the second fluid. The meter is configured to sense reverse flow when the second fluid flows from the outlet section to the inlet section.
