Meter register and remote meter reader utilizing a stepper motor

Abstract From the Canadian patent

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 …
