Important Note: The instrument can be damaged if the connectors and/or the
union nuts are attached too tightly. Only hand-tighten the union nuts for the hose
mounts. If necessary, hold the connectors with a tool (SW 22).
The measuring instrument can be integrated into the measurement and analysis
process using tubing (ID 13 mm) or a fixed connection (PVC system component
pipework, compatible with 1" union nut).

With samples that tend to emit gases, bubbles may form in the measuring
chamber. This causes extremely strongly fluctuating measurement values. In the
event of strongly fluctuating measurement values, replace the diaphragm plate in
the drain connector.
Note: Observe the flow quantity and flow direction of the sample provided in the technical
data.
