A method of manufacturing a cartridge for a fluid treatment system, wherein the cartridge includes a housing defining at least one chamber for a fluid treatment medium, includes providing a cartridge housing part including at least one wall defining at least one opening closable by a filter element. The filter element includes a porous body for at least mechanically filtering fluid flowing into the filter element through at least one first surface area of the filter element, through the porous body and out through at least one second surface area of the filter element. The filter element includes a rim, covering at least a peripheral face of the porous body so as to frame the first and second surface areas. The filter element is combined with the cartridge housing part so as to close at least one of the at least one openings by bonding the rim to the cartridge housing part.

Method of manufacturing a cartridge for a fluid treatment system

It is described a method of measurement of the volume Vof the flow-rate of electrically conductive liquids the conductivity of which is at least codetermined by at least one parameter p, wherein the liquid flows through a vessel having a predetermined shape, and wherein the respective filling volume Vis determined by at least one measured value x, which is measured by an electrical conductivity measuring device comprising electrodes, wherein the vessel is filled in succession and then is emptied through its outlet, through which the filling heights h are constantly changing. At least one reference table comprising calibration measured values xand filling volumes Vbelonging to them is constructed by means of calibration measurements using several liquid samples, which have different p-values and different filling heights h in the vessel. The measured values x are measured in time intervals and the respective filling volumes Vare determined by comparison of the respective measured values x with values xof the table, and the volume Vof the rate of flow is determined from the filling volumes Vover a time period. The measuring device for the determination of the volume Vof flow rate of electrically conductive liquids through a vessel comprises at least two measuring electrodes.
