Do - Align pipe accurately. Piping
should be accurately aligned and
of correct length. The high pressure
body of the flow meter can with-
stand shock and flow/pressure pul-
sation. However, the piping should
be firmly supported by external
mounting brackets, both upstream
and downstream of the meter, to
avoid any pipe flexing actions that
could reduce meter life.
Do - Use rigid mounting. If the flow
meter inlet or outlet are to be rigid-
ly mounted, and the opposing port
is to be connected to flexible hose,
the end connected with the flexible
hose must be rigidly mounted.
Do - Use Teflon® tape for sealing
NPT fitting.
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 (flow 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 fluid is traveling
in the direction of the flow arrow
(Figure 4 on page 8).
INSTALLATION RECOMMENDATIONS
The in-line flow 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) filter. The meter will al-
low particulate to pass that would
jam most valves and flow controls.
Systems that do not have filtration
should be equipped with at least
a 200 mesh (74 micron) filter. Most
hydraulic systems already have
much finer filtration.
Dirt, ferrous metal or sealing agents,
such as Teflon® tape may lodge and
cause malfunction. If the meter is
jammed at a fixed position, follow
cleaning and maintenance instruc-
tions.
Don’t - Use thread locking com-
pounds as thread sealant.
Don’t - Install the flow meter near
turbulence producing fittings such
as elbows, reducers, close coupled
valves, etc. The in-line flow meter
does not require flow straighteners
or special lengths of straight inlet/
outlet piping to stabilize turbulent
flow patterns. However, to assure
maximum operational reliability,
avoid installation of elbows, valves
and/or reducers immediately adja-
cent to the meter inlet.
