Intended use:
• The product may not contain any ferromagnetic particles or solids. It may be necessary to nstall magnetic filters or mechanical filters.
• The product must be sufficiently liquid and free of deposits.
• Avoid pressure surges and pulsing flows.
• Open valves slowly. Do not use solenoid valves.
Use suitable measures to eliminate compression vibrations during gas measurements:
• Short pipeline lengths to next restriction
• Nominal pipe size not greater than nominal device size
• Use of floats with damping

Ingress protection

The measuring device meets all requirements of ingress protection IP66/68.
Therefore it is essential to observe the following points.
• Use only original gaskets. They must be clean and free of any damage. Defective gaskets must be replaced.
• The electrical cables must be undamaged and must comply with regulations.
• The cables must be laid with a loop 3 upstream of the measuring device to prevent water from getting into the housing.
• The cable feedthroughs 2 must be tightened.
• Close the unused cable feedthroughs using blanking plugs 1.
