Abstract
A fiberoptic transceiver system for use in an industrial paint spraying apparatus where analog information from flow sensors in the flow meter on the spray head is converted to a single channel digital signal for transmission on a fiberoptic cable to a receiver for decoding into an analog signal representing flow rate and a signal indicating flow direction. The encoding of two signals onto one channel is accomplished by encoding the flow rate as the frequency of the digital signal and the direction as the pulse width. The direction of the flow is determined by comparing the two analog signals from the flow meter and determining which signal is lagging the other.
