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 product.
• Correct connection of the built-in electrical equipment.
• Visual inspection for damage of the exposed wire lines of the ring initiator inside of the
indicator.
• Observe the additional mounting information for the panel mounting versions.
For further information refer to
Mounting
on page 10.
5.2 Operation
Variable area flowmeters must be operated in such a way that they remain within the maximum
and minimum permissible temperatures and pressures and the electrical limit values.
Variable area flowmeters may only be operated if the equipment parts necessary for safety are
effective in the long run, and are not rendered inoperable during operation.
Adjusting the limit switch during operation is permitted. To do so, first remove the protective
cover. Use the two clamping screws 1 to fasten the limit switch 2 to the back rail 3 of the
variable area flowmeter.
Close the protective cover immediately after adjusting the limit switch.
Observe the additional mounting information for the panel mounting versions.
For further information refer to
Mounting
on page 10.
Figure 5-1: Fastening the limit switch
CAUTION!
Avoid pinching or damaging the wire line of the limit switches when setting the switches and
closing the cover. It should be laid in the grooves of the back rail. In case of damage, the variable
area flowmeter must be replaced!
