Installation
For optimum performance, install the ow meter on the discharge side of the pump, in one
of the congurations shown on page 11.
The following items and conditions should be considered:
Location: Install the ow meter in a clean, dry area if possible. Avoid areas with high vibration levels.
Line and Bypass Valves: These valves allow lter cleaning or ow meter removal without completely shutting the system
down and draining the lines. They are important for system start up under conditions which could damage the meter,
such as: air in the lines, solid materials (at room temperature), high temperature materials, or initial line surges.
Filtration: Any dirt present in the system can jam or damage the meter. A 150 micron lter is generally recommended,
although materials with very high viscosities may require a coarser lter. For bidirectional ow applications, use a lter
on each side of the ow meter. Materials with brous or non abrasive particulate matter may have to be run without
lters. Follow the recommendation of your Max Sales Engineer or consult Technical Service.
Clean Plumbing: Before installing the ow meter, clean the inside of the pipe line with compressed air or steam
(especially when using new pipe). Don’t use water, steam, or compressed air on the meter itself! Remove any protective
covering from the anges (if applicable).
Pipe Threading: When installing pipe to the ow meter, support the nearest end cap or both end caps (as in a vise). Don’t
clamp the ow meter body. This avoids possible misalignment of ow meter components when the pipe is screwed tight.
Check for proper ow meter operation by rotating the timing gear through the transmitter mounting hole. It should
move freely and without noise.
High Temperatures: Use the “Vertical Installation” drawing. This minimizes heat transfer by convection from the
ow meter to the transmitter. The transmitter is the most heat sensitive element in the system and the transmitter
manual should be consulted for specic limits. Optional heating uid ports are available for the ow meter to keep it at
operating temperature during standby conditions. For substances that are solid at room temperature, these ports are
generally required to keep the material molten and owing through the meter.
ANSI Flanges: Using the 241, 242 or 243 meters at pressures greater than 500 psi will also require anges. See the
specications and bolt torque table on page 12. Max has bolt kits available for ange installations.
