Abstract
A double flow rate meter (1) and an apparatus for automatically feeding animals with liquid food which utilizes the flow meter (1) for establishing the amount of food consumed is disclosed. The flow rate meter (1) comprises at least two circular flow passages (2, 20), each containing a ball (11, 12) constrained to be propelled through the relevant channel by fluid proportionally to the flow velocity of the fluid. The balls (11, 12) pass respective sensors (15, 16) in the flow passages. Each flow passage (11, 12) has its own inlet conduit (3, 5) and respective outlet conduit (21, 22), the outlet conduits merging into a single, common outlet conduit (4) leading to a nipple (37) or the like food dispensing means. The flow rate meter enables controlled feeding of an animal with liquid food while medicine or another compound can be administered simultaneously and proportionally to the supplied food. By using such flow meter (1) and control valves in the form of hose clamps (35, 36, 50) the entire system can be easily cleaned.
