Abstract
Affixed to or positioned opposite the glass housing of a watt-hour meter which has a rotating disc with an indicator mark on its periphery is a device for indicating the rate of rotation of the disc. The device has two spherical lenses disposed generally in the plane of the disc along a line which is generally perpendicular to a radius of the disc and preferably symmetrically positioned on opposite sides of the radius. A first fibre optical cable couples visible light from an incandescent source to the first spherical lens to focus light on the periphery of the disc and a second fibre optical cable couples visible light collected by the second spherical lens focused on the periphery of the disc to a photoresistor.
