Do - Align pipe accurately. Piping
should be accurately aligned and
of correct length. The high pressure
body of the ow meter can with-
stand shock and ow/pressure pul-
sation. However, the piping should
be rmly supported by external
mounting brackets, both upstream
and downstream of the meter, to
avoid any pipe exing actions that
could reduce meter life.
Do - Use rigid mounting. If the ow
meter inlet or outlet are to be rigid-
ly mounted, and the opposing port
is to be connected to exible hose,
the end connected with the exible
hose must be rigidly mounted.
Do - Use Teon® tape for sealing
NPT tting.
Do - Install unions. Install a union
near the inlet or outlet of the meter.
This will facilitate quick, easy meter
removal and inspection during peri-
odic maintenance procedures.
Do - Mount the meter either
horizontally or vertically (ow arrow
pointing to either side or straight
up). If the meter must be mounted
inverted, special inverted scales are
available from the factory.
Do - Ensure the uid is traveling
in the direction of the ow arrow
(Figure 4 on page 8).
INSTALLATION RECOMMENDATIONS
The in-line ow meter is a simple device to install. However, the following
measures are recommended for reliable, trouble-free operation:
Do - Use at least a 200 mesh (74
micron) lter. The meter will al-
low particulate to pass that would
jam most valves and ow controls.
Systems that do not have ltration
should be equipped with at least
a 200 mesh (74 micron) lter. Most
hydraulic systems already have
much ner ltration.
Dirt, ferrous metal or sealing agents,
such as Teon® tape may lodge and
cause malfunction. If the meter is
jammed at a xed position, follow
cleaning and maintenance instruc-
tions.
Don’t - Use thread locking com-
pounds as thread sealant.
Don’t - Install the ow meter near
turbulence producing ttings such
as elbows, reducers, close coupled
valves, etc. The in-line ow meter
does not require ow straighteners
or special lengths of straight inlet/
outlet piping to stabilize turbulent
ow patterns. However, to assure
maximum operational reliability,
avoid installation of elbows, valves
and/or reducers immediately adja-
cent to the meter inlet.
