Abstract:
1. A liquid delivery system comprising: at least one liquid storage tank; a manifold; an integral manifold vent system communicating directly with the manifold and comprising a manifold vent valve and a manifold vent pipe; a first liquid sensor; a delivery outlet flow restrictor; and a manifold-air system, the manifold-air system comprising a manifold-air flow restrictor operable to allow air to enter the manifold, when the manifold-air flow restrictor is opened, wherein the manifold is provided with an inlet and an outlet, the inlet of the manifold being connected to the at least one liquid storage tank; the delivery outlet flow restrictor is located downstream from the manifold; the first liquid sensor is adapted to detect the formation of an air pocket in the manifold; and the integral manifold vent system is operable to allow filling of the manifold with the liquid being dispensed when the manifold vent valve is opened to release trapped gas.
