Abstract

A meter for flowing material, e.g., water, has a meter register having an electronic display, e.g., an LED or LCD display, and a mechanical read-out display driven by a stepper motor to record units of water that flowed through the meter. In the event of an electrical power failure, the LED or LCD readout values are lost, however, the mechanical read-out values remain. Further, signals are transmitted to a microprocessor of a meter register to change the rotation of the stepper motor so that the meter register can be used with different types of meters. Still further, a meter generator co-acting with a meter register forwards an electrical pulse signal after a quantity of material or utility passes through a water meter to a microprocessor of a remote reader. The remote reader includes an odometer coupled to a stepper motor.
