Inlets and outlets for flow measurements remain a hot issue: many applications do not offer the appropriate installation conditions to maintain the recommended or required straight inlet and outlet runs. KROHNE presents the appropriate "0D/0D portfolio" for this purpose, consisting of the WATERFLUX water meter, the OPTIFLUX for wastewater, and the AF-E 400 for auxiliary and supply circuits, which can be used without straight inlet and outlet sections.

For more flexibility and efficiency, we present the modular Water Analysis Panel, a multi-parameter measurement system for water treatment applications. It consists of individual modules that can be combined to measure dissolved oxygen, turbidity, conductivity, pH and ORP. Depending on the requirements, the measuring system can be operated as a complete solution or with selected individual modules.
