Lubrication
The TERZ 94 is fitted with permanently lubricated bearings up to and
including the nominal diameter of DN 150. From the nominal diameter of
DN 200, the meter is fitted with a lubricator. The type of lubricator and the
lubrication instructions depend on the nominal diameter and the pressure
rating:

Please observe also the instruction plate on the case.
In the case of unfavourable operating conditions, such as the formation of
water or hydrocarbon condensate or the use of dust-laden gas, we would
recommend performing lubrication at shorter intervals, even daily under
extreme conditions (permanent formation of condensate).
Recommendations for lubricating oils:
Aero Shell Fluid 12 or another oil with 2 to 4°E at 25°C as per MIL-L-6085 A
specification.
