6.3 Maintenance
We recommend that meters that are in constant use are inspected every month.
Servicing of the meters can be divided into the following main areas:
Inspection of external condition
Clean the outside of the meter with a cleaning agent that removes oil, and check for any external damage.
Checking the free movement of float and cone
When the oil input for each meter unit is closed, the float (6) should move down on to the cone (5). The floats
in some meters may move down only after a delay. This delay occurs because oil is still flowing through the
meter, for example because of oil returning from lubrication points higher up.
Inspection of internal parts when necessary
Float, cone, adjusting components and gaskets. Take the meter apart, check all components and reassemble.
Special care is needed when installing glass tubes, gaskets and flanges.
Any damaged parts should be replaced. Order details for spare parts are given in the spare part drawings.
6.4 Spare parts and modification kits
Figures 1 to 6 show the spare parts and components of the SF meters that are included in the sub-assemblies
in question. KIT1 is a seal kit, KIT2 is a cone kit, KIT3 contains a glass tube and the necessary seals. KIT4
includes a series of modifications for SF05-15 meters and a glass tube/cone series for SF20-30 meters. Ther-
mometer kits contain all the thermometer components of the model in question.
The pictures of the alarm spare parts (Figures 7 and 8) show the spare parts for the BSC and BSS models.
Figure 9 gives a more detailed breakdown of the alarm sensor components.
