Meter operation
Fluid enters the inlet port and then passes through the metering chamber. Inside the
chamber, fluid forces the internal gears to rotate before exiting through the outlet port.
Each rotation of the gears displaces a specific volume of fluid. As the gears rotate, a
magnet on each end of the gear pass a reed switch in the top-mounted register's circuit
board. The reed switches send pulses to the microprocessor in the register to change the
LED display segments.
