START-UP:
Begin with all valves closed.
-  Slightly open the upstream valve to pressurise the meter line. The pressure variation should not
   exceed 0.3 bar per second. When the pressure is balanced, fully open the upstream valve.
-  Slightly open the downstream valve. The valve should be opened a small amount to maintain:
      •  The upstream pressure in the meter line.
      •  A low flow rate in the meter during the downstream pressurisation ( approx. 5% Qmax). 
When the downstream pressure is balanced, the downstream valve can be completely opened.
SHUT DOWN:
-  Very slowly close the downstream valve and check that the meter is no longer recording.
-  Close the upstream valve.
-  Slowly open the small bleed valve V2. The pressure variation should not exceed 0.3 bar per
   second.
-  Some gas still inside the meter and the pipe, therefore sufficient ventilation is required.
5. 4 Meters placed after a regulator
Installation has to be done in accordance with the technical manual of the specific regulator. During 
pressurisation and depressurisation, insure that the pressure variation should not exceed 0.3 bar per 
second.

6 Maintenance 
6.1 Maintenance of the meter
Once installed, the meter does not require any specific attention except a periodical check or 
change of the lubricant filled in the covers.
After start-up:
Natural gas: After the preliminary term of service, the lubricant level should be checked.
Other gases: After a working period of 100 hours from commissioning, the lubricant level should be
checked.
If the lubricant level is appreciably low, if the lubricant is emulsified or if there is a chemical reaction
between the lubricant and the gas, the lubricant should be reassessed and changed to fit the
prevailing conditions.
Periodical change of lubricant:
The period between checks or changes of lubricant depends of the operating conditions (pressure
variation, flow rate...).
Natural gas: Under normal conditions, lubricant has to be changed every 5 to 8 years.
Other gases: Please consult us.
Use solvent and alcohol free product to clean the meter.
Repair must be done only by qualified personal. Afterwards a tightness test with 1.1 x PS (Pmax) 
must be performed.
If used with wet gas, internal and external effect of corrosion has to be checked regularly and in 
case of severe corrosion, the meter has to be replaced.
