Preserving the flowmeter
1. Close a connection of the flowmeter with a blind flange.
2. Position the flowmeter vertically.
3. Fill non-corrosive and resin-free oil up to approx. 1 cm under the connection at the top, while turning
the measuring unit slowly, so that the measuring unit also comes into contact with it.
4. Close the upper connection with a blind flange.
5. Apply non-corrosive and resin-free oil to all the plain and unpainted parts of the outer housing.
After about six months storage check the oil level in the flowmeter and if necessary top up oil. Check the
preservation of the outer housing and if necessary apply oil to the parts again.
Notice:
Store the preserved flowmeter cool and dry and protect it against direct sunlight.
Notice:
After a longer storage time the manufacturer recommends that you have the flowmeter recalibrated, see
"Re-calibration of the flowmeters", page 34.
