IMPROVED LIQUID METERING AND FLUIDIC TRANSDUCER FOR ELECTRONIC COMPUTERS ABSTRACT OF THE DISCLOSURE The invention relates to fluidic transducers of electrical signals from an electronic computer for ac- curately metering flow of a liquid to a utilization device. A liquid filled hollow channel means is accelerated along the flow axis thereof to produce a fluid control signal for a bistable fluidic switch element with a cross-over type interaction channel and a common outlet to a pair of output passageways. In a preferred embodiment, electrical signals from an electronic computer are supplied to a coil centered by a spring in a magnetic field,first in one direction of current flow and then in the opposite direc- tion,to introduce bidirectional movement of the coil and the hollow channel means coupled thereto. The signals are preferably frequency modulated (but may be pulse width modulated). The switching speed of the bistable switching element enables close tracking of the computer signals and a more accurate metering of liquid flow to the utilization device.
