Inductive conductivity meter, ELEMENT Design

The Bürkert inductive Type 8228 conductivity meter is used in many industrial processes where measurements are required in aggressive or concentrated media such as acids, alkalis or liquids with high salt contents and a wide measuring range. Applications like cooling water monitoring (i.e. dilution control), industrial water treatment or the preparation and identification of cleaning liquids, for example in CIP processes. The device is available in two variants:

• The first is the standard variant with a G 2″ process connection to be mount in Type S020 fitting
• The second is the CIP variant with a 2″ clamp process connection according to ASME BPE (1.5″ clamp on request).
