To insert oil:
The meter must be depressurized in order to be filled with oil.
Unscrew the oil filler neck (Fig. 11 | No. 1) depending on the installation
position of the meter.
If an oil-level inspection plug (Fig. 11 | No. 2) is fitted, unscrew it.
Insert the oil specified in Table 4 through the oil filler neck using the
supplied syringe (inspection kit ID No. 73016605 or 73014893).
The oil quantity is correct when the oil is visible in the threads of the oil-
level inspection borehole (Fig. 11 | No. 2) or in the centre of the inspection
window.
After filling, the plugs must be inserted again together with the O-ring and
tightened with a torque of 9 Nm.
Commissioning:
Slowly fill the system until the operating pressure is reached.
The pressure rise must not exceed 350 mbar/s.
A bypass line should be used for filling (recommendation:
12 mm pipe diameter).
Do not exceed the measuring range of the gas meter even briefly.
A tightness test must then be carried out.
4. Maintenance
INFORMATION!
Once it has been commissioned, the measuring instrument does
not require any special maintenance or oil-level inspections. The oil
must generally be replaced after a maximum of 5 years.
If a meter with oil-level gauge glasses (optional) is used, the oil
change interval can be extended to 8 years provided that the oil
level is checked at least once a year. To check the oil level
correctly, the meter should not rotate quickly.
CAUTION!
It is essential to drain the oil before transport. Otherwise, the oil will
get into the measuring chamber and damage the meter.
CAUTION!
Never transport a rotary gas meter containing oil.
