Precision dispensers for fluids from 0 to 1˙000˙000 mPa∙s

The volumetric dispensers exploit the typical incompressibility characteristics of more or less viscous liquids, able to occupy all the volume in which they are restricted.

For the metering of a required volume the metering valve chamber of defined dimensions is used (Pneumatic Volumetric Dispensers), or otherwise the continuity of the flowrate is utilised in ducts of known capacity (Electronic Volumetric Dispenser). In the latter case the metering is dispensed with a controlled flowrate and defining the feeding time, controls the volume dispensed.
