OVERALL DIMENSIONS
RECOMMENDATIONS
1. Consider the overall dimensions of the assembled unit before installation. Allow adequate
clearance for the meter and any associated electronics. The Measuring Unit should
always be positioned away from the wall with the register top horizontal and facing up.
2. The installation should include a high quality, low pressure loss shutoff valve upstream of
the meter. To prevent water damage to customer property when service is required, a
downstream shutoff valve is likewise recommended.

3. The installation should be leak-tight, with properly sized gaskets. When meter couplings are
ordered from Master Meter, gaskets are provided. Appropriate gaskets and couplings are
also available from qualified waterworks distributors. Whenever a meter is pulled from the
line, discard and replace old gaskets.
4. The Flexible Axis Meter can be installed using either meter couplings or solder-joint
connections. When soldering, take care not to apply heat to the polymer components of
the meter. Any resulting damage will not be covered under warranty.
5. Although AWWA opposes the grounding of electrical systems to potable water delivery
lines, such practices do exist. To prevent accidental harm to service personnel and
residents, make certain that an electrical grounding strap is installed around the meter.
AT THE TIME OF THE INSTALLATION
The FAM Flow Tube will be shipped with either a Plug or Measuring Element in Place. The
Plug allows full flow through the tube for system pressure testing and line flushing. If the plug
is in place when received, do not remove it until the Measuring Unit is to be installed (after
pressure testing and line flushing). Removing the plug can damage the o-ring seal, causing
leaks to occur. A new set of o-rings is shipped with the FAM Measuring Unit, for use when the
Measuring Unit is connected to the Flow Tube.

INSTALLING THE FAM TUBE WITH PLUG
1. Install the FAM Flow Tube with Plug in the line;
make sure the arrow on the Flow tube is pointing in the
direction of water flow.
2. When installing the FAM Flow Tube with Plug, be sure to
vertically level the Plug for future replacement with FAM
Measuring Unit. Turn tap on to release any trapped air in line to
the house/apartment. After air is released spot check for leaks
around the installation
INSTALLING THE FAM TUBE WITH MEASURING UNIT
1. Install the FAM Tube with
Measuring Unit in the line;
make sure the arrow on the
Flow tube is pointing in the
direction of water flow.
Before completely tightening
the couplings or soldering,
make sure the Measuring unit
is vertically level.
Turn locking nut clockwise to loosen.

2. After Installing and
leveling the meter vertically,
check to see if the
Measuring unit is level
horizontally. Level the
Measuring Unit by loosening
the locking nut clockwise,
adjusting the Measuring Unit
and tighten nut counter
clockwise.
REPLACING THE PLUG WITH MEASURING UNIT
1. Loosen the Locking Nut with FAM wrench and
take plug out
2. Replace both O-rings that are in the Flow Tube with new ones that were shipped with
the FAM measuring Units. Apply a little lubricant on o-rings during this procedure.
Turn locking nut counter-clockwise to
tighten.
