Abstract: An apparatus and method for controlling the flow of fluids such as liquids or gasses. The apparatus may include an input control valve, an input manifold, first, second, and third further control valves, first, second, and third flow meters, first, second, and third check valves, and an output manifold. The apparatus may further include a control central processing unit which controls the input control valve, the first, second, and third further control valves, and the output control valve. The control central processing unit may receive one or more signals concerning fluid flow through the first, second, and third flow meters and may control flow through the meters by controlling one or more valves. Each of the first, second, and third flow meters may be a coriolis flow meter.
