A pulse transmitter for fluid metering includes concentric gearing, with the exciter gear concentric with the main shaft in the center. Because of this concentricity, one can put practically any number of additional coils (typically four) to get four or more outputs. Also, each coil could be dual output to get eight outputs from four coils. Each coil preferably produces 1000 pulses per revolution of the main shaft. Because of its compactness and light weight, this pulse transmitter has a more practical application in the liquid metering industry than prior transmitters.
