This guide is designed to assist you in the assembly of the Master Meter Multi-jet (BLMJ) meter
used in the 2018/2019 Meter Madness Regional and National competitions. These steps do
not have to be followed in this precise order for the competition. Use any tactical advantage
you find, within the rules, to decrease your assembly time and increase your chances of
winning the competition.

1) Insert the Regulator O-Ring into the body.
•Note, Master Meter recommends placing the O-Ring in the body before the event begins.
2) Insert Rotor into Chamber Housing. Note orientation below.

3) Insert the Regulator into the Chamber.
4) Insert the Chamber Top Plate onto the Chamber Housing. Listen for a “click” as the top plate
locks in place.
Note: The Regulator has a direction arrow
and screw slow, as shown in this image. The
direction that the arrow points is not
important for the competition. Just be sure
this part faces up when inserting into the
chamber.

5) Insert the Chamber into Strainer.
6) Insert the Chamber and Strainer into the Meter Body. Be sure to line up the regulator with the hole
in the meter body. If the O-Ring is not properly seated, or if it is missing, the meter will leak.
NOTE: The strainer/chamber O-Ring is not
needed for competition. If you receive this
gasket with your meter, you may discard the
gasket.

7) Install Sealing Plate and Sealing Plate O-Ring. If Sealing Plate is installed upside down, the O-Ring
will not line up. Pay attention to install in the correct direction with the groove pointing out.
8) Place Bottom Plate onto meter body and secure in place with the supplied bolts. Tighten with a ½”
wrench.

9) Turn meter over and place register on bayonet at an approximate 45° angle as shown in the image
on the left.
Secure register in place by turning clockwise as shown in the image on the right.
Note: The meter will be shipped with a locking
pin for the register. To remove the register and
shroud, use a punch or awl to drive the locking
pin into the register shroud. The locking pin will
not be used for the competition.
Have fun and we wish you the best of luck.
