Abstract
An electronic, programmable meter register (10) includes an input section (18, 19, 30) for generating pulses in response to units of flow in a water meter, a stored control program (46), a microelectronic CPU (31) for executing the program (46) to read input pulses and to transmit output data representing units of flow volume. An output device (16) is responsive to output data from the CPU (31) to display units of flow volume, and the CPU (31) stores a programmable meter input resolution factor for a corresponding one of several meters that scales the output data that is transmitted to the output device (16). A magnet (49) is held outside the register unit (10), but in proximity to a reed switch (22) inside the sealed unit (10) to sequence the display (16) through a series of totalization, rate of flow and other screen displays. A magnetic pulse pickup (24, 18, 19) is provided to signal both forward and reverse flows.
