ABSTRACT:
A method and apparatus for controlling the amount of fluid (12) pumped to a using implement by a fluid distribution system (10) is the subject of this application. The apparatus includes a weir chamber (40) into which fluid diverted from a fluid supply line (22) into a return line (36) floods. A head is generated in the chamber (40), the height of the head depending upon the volumetric rate of residual flow through the return line (36). Sensing means (52, 54) are provided in the chamber (40) to sense the volumetric rate of flow of diverted fluid. The amount of fluid (12) pumped through the supply line (22) is controlled, in response to the head sensed in the weir chamber (40), by a controller unit (62) which governs operation of pumps (24) pumping fluid (12) through the supply line (22).
