<p>In order to improve a device for geometry measurement on a workpiece, comprising a housing having a flow channel, in which a nozzle is disposed to be permeated by a measuring fluid in a measuring fluid flow direction, so that it allows particularly precise geometry measurements, it is proposed that at least one flow calming unit be provided, which is disposed in front of or behind the nozzle viewed in the measuring fluid flow direction.</p> |
