Installation and Removal
The gear wheel flow meter has been tested at the factory before delivery and is ready for
operation immediately after installation and connection of the electrical cables. The built-in
meter should be accessible for visual inspection at any time during operation.
Attention:
In the event of damage to the gear wheel flow meter, a pressure safety
device must be provided in the system to prevent the maximum permissible
pressure of the volume sensor or other components in the system from being
exceeded (pressure relief valves). It must be ensured that the flow meters are only
held by the housing during installation and transport, never by the plug.
