This is cumbersome and time consuming.
  • the metering device for the metered intake and / or delivery of a liquid comprises, in a manner known per se, firstly a piston device arranged in a housing and a device for determining the piston travel and / or the position of the piston.

  • the scale can be formed in a basically arbitrary manner on a flat surface, applied, printed, glued or produced in any other way or even on an arbitrarily curved surface, for example on the cylinder outer surface of the housing, a piston cylinder or the piston.
  • the scale may be formed in the case of a reciprocating piston as a linear scale and in the case of a rotary piston assembly as an arcuate, in particular arcuate, scale.
  • the measuring device has a microprocessor-controlled evaluation unit and a display unit.
  • the ascertained position mark of the binary scale can be analyzed and, for example, by image comparison and consideration of certain parameters, such as piston or cylinder diameter, zero value, scale factor and lifting height, a certain volume be assigned (parameterization).
