Maintenance and cleaning
The VO is maintenance-free.
If the oval gear flow meter will not be in operation for a longer period of time, it has to be
dismounted, thoroughly cleaned and conserved with acid-free oil. Oval gear flow meters used
for liquid food may not be preserved in this way. In- and outlet are to be covered with caps.
Make sure to store the oval gear flow meter in a dry room.
Cleaning of the oval gear flow meters
The oval wheels have to be dismounted if the pipes are flushed with hot water.
•
Loosen the screws on housing cover, lift housing cover with pressure screws, pull off
oval wheels from axle, handle with great care, do not place on stone floors, use support
made of wood or rubber material.
•
When mounting, put on the oval wheels toothed in, i.e. in a way that the M marks on the
wheel face each other. Turn the oval wheel manually to make sure they are properly in-
serted (once). When inserting the gaskets, make sure it fits precisely.
