3. Installation
•
The sensor may be installed in any position,although
horizontal fl ow is recommended (the sensor mounted upright).
If the sensor is not installed upright, the linearity error may be
greater in the lower part of the sensor's measurement range.
•
Mounting tabs are provided using M4 or #8 self-tapping
screws (customer supplied). See Dimensions illustration for
mounting tab hole pattern specifi cations.
•
Install sensor with the arrow pointing in the direction of fl ow.
•
Always maximize distance between the sensor and pump
source. Never install immediately downstream of valves,
fi ttings, etc. For optimum performance, a straight fl ow run of
at least 100 mm to 150 mm (4 to 6 in.) should be provided
before and after the sensor.
• Two
pipe
fi tting adapters (included) convert the G 1/4 in.
straight threads to 1/4 in. NPT pipe threads. Hand tighten
only! Apply 1-2 turns of PTFE sealing tape to all threaded
connections to prevent leaks..
Installation Hints
•
Avoid vibrations and shocks.
•
Avoid solids in the fl uid.
• Install
a
fi lter or line strainer upstream to protect sensor.
