13. Maintenance and lubrication
Meters without oil pump are maintenance-free.
Meters with oil pump must be lubricated.
- You must open the cover of the supply tank before
operating the oil pump’s hand lever.
- Ensure that the supply tank has an adequate quantity of
oil. Use the filter insert in the supply tank when topping
up with oil.
- Operate the oil pump by hand by fully pulling the hand
lever down applying uniform pressure. Note that one pull
corresponds to one stroke of the pump’s piston.
- After operation, you must re-close the supply tank firmly.
Lubrication instructions for turbine gas meters and quantometers
in the case of dry natural gas
DN 50 – DN 200 DN 250 – DN 600
4 – 6 strokes every 3 – 4 months 6 – 10 strokes every 3 – 4 months
10 strokes on commissioning
(initial lubrication)
15 strokes on commissioning
(initial lubrication)
Permitted lubricants:
Shell Risella 917
Shell Tellus T 15
Other oils not containing resin and acid, with a viscosity of approx. 30 cStokes at 20°C,
solidification point lower than -30°C, or equivalent oils may be used.
Important!
- Always fill the supply tank with oil in good time to prevent air entering the pipe system.
- Protect the oil pump against the ingress of water by keeping the oil tank firmly closed.
14. Care and cleaning
- Clean off dirt on the meter only with a damp cloth.
Any media gentle on the applicable materials can be used as cleaning media.
- Do not clean the transparent tank of the oil pump with solvent.
15. Recycling and environmental protection
ELSTER has reduced the transport packagings of the measuring instruments to the bare
essentials. Packaging materials are always selected consistently with a view to recycling. The
cardboard items used constitute secondary raw materials for the paperboard and paper industry.
The Instapak® foam packaging items are recyclable and can be reused.
Plastic sheeting and strips/bands are also made of recyclable plastic. At ELSTER, subsequent
recycling and disposal are already elements of the product development process. When
selecting the materials, we allow for reusability of the materials, suitability of materials and
subassemblies for dismantling and separation, and the risks of environmental pollution and
health risks when recycling and dumping on landfill sites. The turbine gas meters and
quantometers mainly consist of metallic materials which can be melted down again in steelworks
and metallurgical plants and which can thus be reused a virtually unlimited number of times. The
plastics used are listed in Annex B so that sorting and separating of the materials for the
purposes of subsequent recycling is possible.
