ABSTRACT:
An apparatus and method are disclosed for reducing flow pulsations and measuring fuel flow in a fuel system for a liquid fuel engine. The engine (54) has associated with it a fuel tank (30) and a pump (32) for causing fuel to flow through a fuel flow path from the fuel tank through the pump to the engine. In one embodiment, the invention comprises a flow sensor (50), gas inlet means (62), and a pulsation damper (46) that includes a chamber (70) in communication with the fuel flowing through the pulsation damper. The flow sensor is positioned in the fuel flow path (44, 48, 52) between the pump and the engine, and serves to measure the rate of fuel flowing to the engine. The gas inlet means introduces gas into the fuel flow path, and preferably directly into the chamber. The pulsation damper is located in the fuel flow path (44, 48) between the pump and the flow sensor, and operates to damp flow pulsations in the fuel and separate the gas introduced by the gas inlet means from the fuel such that the gas does not reach the engine.
