Operation
5.1 Start-up
Make the following checks before starting up the device:
• Suitability of the materials used for the measuring unit and for the gaskets for adequate
resistance to corrosion from the process product.
• Correct connection of the built-in electrical components.
• Visual inspection of the single-core non-sheathed cables of the ring sensors, laid inside the
indicator, for signs of damage.
5.2 Operation
The limit switches can be set during operation. To do so, first remove the protective cover. Fix
the limit switch 2 to the back rail 3 of the variable area flowmeter using the two clamping
screws 1. Close the cover immediately after the limit switches have been set.
CAUTION!
Avoid pinching or damaging the single-core cable of the limit switches when setting the switches
and closing the cover. It should be laid in the grooves of the back rail. If the cable is damaged in
any way, the variable area flowmeter will need to be replaced!
