Meter register having an encoder
First Claim
1. A meter register, comprising:
- a register body having a rotatable drive shaft coupled thereto;
an energy passing member co-acting with the drive shaft such that as the shaft rotates the member rotates, the member having a first surface, an opposite second surface, a first portion having a predetermined percent transmission to wavelengths of the magnetic spectrum, and a second portion having a predetermined percent transmission to wavelengths of the magnetic spectrum, wherein the first predetermined percent transmission of the first portion is greater than the predetermined percent transmission of the second portion;
a device to emit energy in a predetermined wavelength range of the electromagnetic spectrum along a path to impinge on the first surface of the member; and
a pair of detectors mounted in spaced relationship to one another, wherein each of the pair of sensors generates a first signal when energy passing through the first portion of the energy passing member is incident thereon and each of the detectors generating a second signal when the energy emitted by the device is incident on the second portion of the energy passing member.

Abstract
A water meter register has a shaft for rotating an energy passing wheel having a high transmission portion and a low transmission portion. Energy rays are directed toward one side of the wheel toward a pair of detectors mounted on the other side of the wheel. Each of the detectors generates a first signal when energy passing through the first wheel portion is incident thereon and a second signal when the energy from the devices is incident on the second wheel portion to determine water volume flow rate. In another embodiment, an electronic device acts on the signals from the detectors to provide an adjusted signal that is a more accurate measure of flow rate. In another embodiment, the register includes a plurality of wheels to display measured volume flow, and a stepper motor mount within the wheels to rotate the wheels to present a readable measured volume flow rate.

12. A meter register, comprising:
-
a register body having a rotatable drive shaft coupled thereto, a drive magnet attached to the drive shaft, at least one measuring arrangement co-acting with the drive shaft, and generating a signal representing measured flow volume of material; and an electronic device acting on the signal to determine the difference between actual flow volume of material and the measured flow of material, and adjusting the signal to provide an adjusted signal, wherein the adjustment is based upon the generated signal as a function of time that is indicative of the measured flow rate of fluid being measured and the adjusted signal is indicative of the actual volume of material being measured.

13. A meter register, comprising:
-
a register body having a rotatable drive shaft coupled thereto, a drive magnet attached to the drive shaft; a measuring arrangement operationally connected to the drive shaft to measure flow volume of material; a display to display the flow volume of material, the display comprising a plurality of wheels, each wheel having an arrangement of characteristics such that the characteristics on the wheel in a given position correspond to the measured volume flow; and a stepper motor mount within selected ones of the wheels and acted on by the measuring arrangement to rotate at least one of the plurality of wheels to present a readable measured volume flow rate.
