Description
As screw meters flowmeters belong to the group of rotating displacement meters. The fluid current
makes the measuring unit rotate. The displacement effect results from the continuous filling, axial
displacement and discharge of the volumes that are formed by the measuring housing and measuring
unit. The measured liquid flows around and lubricates all the rotating parts. Thanks to the displacement
principle, the flowmeter does not require inlet and smoothing sections in its supply and discharge.
Depending on the customer requirements, the flowmeters can be equipped with suitable end
connections for connection to various flanges.
