Bottle dispenser having a digital volume display
First Claim
1. A dosing device for receiving and/or dispensing a dosed amount of a liquid, the dosing device comprising:
- a piston device which is disposed in a housing; and
a device for determining the stroke of the piston and/or the position of the piston along an axis of motion representing a direction of relative motion between the piston and the housing,wherein the device for determining the stroke of the piston and/or the position of the piston includes at least one scalar element and at least one measuring device, wherein the at least one measuring device includes at least one sensor configured to read the scalar element,wherein either;
the scalar element is fixedly disposed at the housing of the piston device and the measuring device is directly or indirectly connected to the piston and can be moved together with the piston, orthe scalar element is disposed at the piston so as to be movable together with the piston and the measuring device is fixedly disposed at the housing,wherein the scalar element is designed as an absolutely coded scale, andwherein the scalar element comprises a series of coded regions positioned along an axis of the scalar element parallel to the axis of motion, each coded region of the series of coded regions having information encoded along a direction perpendicular to the axis of motion, wherein each coded region represents a value designating an absolute position along the axis of the scalar element.
