MTU Instruction
for Dresser Gas Meters with Vertical Mechanical Index
Step 8 – Place the pulser on the index
base plate, aligning the bottom coupler on
the pulser with the wiggler on the meter.
Align the corner mounting holes on the
pulser with the mounting holes on the
index base plate.
Step 9 – Fasten the pulser to the
instrument drive using the four 5/16-18 x
3” slotted, stainless steel round head
bolts provided. Install security cups, if
desired, as shown below.
Step 10 – If the index box assembly has
a silicone gasket applied around its
bottom edge and that gasket is in good
shape, you can discard the index cover
gasket supplied with the pulser and skip
to Step 11. Otherwise, place the index
cover gasket on the pulser, aligning the
gasket as shown below.
NOTE: When using the cork gasket
supplied with the pulser, be sure that the
bottom edge of the index box is clean and
free of any silicone and/or dirt particles.
