Description
The +GF+ SIGNET 2507 Mini Flow
Sensor contains a free-running rotor that
is driven by the fluid flow. Within the
given measurement range, the rotational
speed of the rotor is proportional to the
fluid flow rate. Permanent magnets built
into the rotor trigger an electronic switch
in the top of the sensor creating a
square-wave output frequency proportional to flow rate. Both opaque and
transparent fluids can be measured from
0.2 to 20.0 centistokes.

Installation
• The sensor may be installed in any position, although
horizontal flow is recommended with the top of the sensor
pointing upward. If the sensor is not installed horizontally, the linearity error may be greater in the lower part
of the sensor's measurement range. Mounting tabs are
provided for surface mounting using #8 or M4 selftapping screws (customer supplied). See drawings below
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, fittings etc. For optimum
performance, a straight flow run of at least 100 to
150 mm (4 to 6 in.) should be provided before
and after the sensor.
• Two pipe fitting adapters (included) convert the
sensor's G1/4 in. straight threads to 1/4 in. NPT
pipe threads for use with common pipe fittings.
