An apparatus 10 for dispensing liquid fuel comprises an inlet 152 in fluid communication with a source of liquid fuel; a first manifold 154 operative to split flow of said liquid fuel from said inlet 152 into first and second parallel branches; first and second Coriolis flow meters 156, 158 in-line said first and second parallel branches, respectively; a second manifold 162 operative to combine flow from said first and second parallel branches; a hose 166 and nozzle 168; and a flow valve 164 operative to permit flow through said hose and nozzle. A valve permits flow through only said first coriolis flow meter and through both of said first and second coriolis flow meters depending on the pressure drop across said first and second manifolds. |
