Omega FP-5070 Series Flow Sensors

3. Installation
• The sensor may be installed in any position, although horizontal
flow 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 specifications.
•
Install sensor with the arrow pointing in the direction of flow.
• Always maximize distance between the sensor and pump
source. Never install immediately downstream of valves,
Installation Hints
•
Avoid vibrations and shocks.
•
Avoid solids in the fluid.
•
Install a filter or line strainer upstream to protect sensor.

4. Wiring Details
4.1 Cable Extensions
The standard 25 foot sensor cable can be extended to 300 m
(1000 ft) using 2-conductor shielded twisted-pair cable.
• Always maintain cable shield through cable splice.
• For splice-free cable replacement up to 300 m (1000 ft), refer
to the sensor plug connection diagram (below) for connection
details.

least 100 mm to 150 mm (4 to 6 in.) should be provided before
and after the sensor.

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.
CAUTION!
Use an adjustable wrench to prevent the fitting
adapters from overtightening while installing mating
pipe connectors. Sensor damage will occur if the ports
are overtightened.
