Abstract
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.
Claims15
Apparatus for monitoring fluid transmission comprising:
- a transmitter for fluid metering, the transmitter including concentric gearing, including a main shaft in the center and an exciter gear concentric with the main shaft in the center;
- means for attaching the transmitter to a meter which measures liquid flow;
- a plurality of coils for producing outputs indicative of the amount of fluid flowing through the meter;
- and
- means for transmitting the output from the fluid metering location to a second location, wherein each coil produces 1000 pulses per revolution of the main shaft.
Apparatus for monitoring fluid transmission comprising:
- a transmitter for fluid metering, the transmitter including concentric gearing, including a main shaft in the center and an exciter gear concentric with the main shaft in the center;
- a plurality of coils for producing outputs indicative of the amount of fluid flowing through a pipeline;
- means for transmitting the output from the fluid metering location to a second location, wherein each coil produces 1000 pulses per revolution of the main shaft.
