b) Mounting

1)

Always  follow  your  company’s  procedures,  and 
applicable local codes and ordinances.

2)

Ensure gas valves are closed.

3)

Ensure  the  upstream  piping  is  clean  and  free  of  any 
debris.

4)

Remove protective caps from meter inlet and outlet prior 
to installation.

5)

Ensure the impellers turn freely.

6)

Ensure  the  direction  of  flow  using  the  arrow  on  the 
nameplate.

7)

Ensure  the  meter  orientation  is  correct.  Impeller  shafts 
must be horizontal [Figure 4].

8)

Connect  the  inlet  and  outlet  pipe  flanges  using 
appropriate  bolts  and  gaskets.  Inlet  and  outlet  pipe 
flanges should be parallel and should not introduce any 
bind on the meter body when tightened.

9)

Level meter to within 1/16" per foot in all directions and 
tighten flange bolts evenly (maximum 80ft-lbs). 

c) Adding Oil

!

WARNING

Add oil only to the index end of the meter.

1)

Ensure gas valves are closed and meter and piping are 
depressurized.

!

WARNING

Failure  to  depressurize  the  meter  prior  to  removing 

meter  and/or  components  could  result  in  personal 

injury and/or property damage.

2)

Remove oil fill plug in the counter end case cover using a 
5mm hex key [Figures 5 and 6].

3)

Using the supplied syringe and oil, slowly add oil until 
it is +/-1/16" of the center of the sight glass [Figure 7]. 

DO NOT OVERFILL.

 Only use Shell Morlina lubricating oil.

!

WARNING

DO NOT remove any sight glasses. No maintenance 

can be performed through these openings.

4)

Reinstall the oil fill plug.
