Installation
Step Four
The FT10 series flow switch must always be in contact with the
liquid being measured. The GT10 series flow switch must never
be submersed in liquid.
Both flow switches feature a 3/4” NPT
threads which will allow it to be used with various types of
fittings. Be sure to check the insertion depth of the flow
switch in the fitting after it is installed. See the diagram to the
right for the recommended insertion depth.
The two tip of the sensor are to be perpendicular to
the flow (as seen to the right). Never mount the tips
with one in from t of the other.
When using any type of fitting, the orientation as well as the
insertion depth of the flow switch in the pipe is critical. See
the diagram to the right for the recommended orientation.
Best location for installation will be along the top of the pipe.
Warning
The flow switch tips have a thin plastic wall which may be damaged if dropped or installed improperly.
The FT10 flow switch is designed for use in liquid. For best results, avoid installing the FT10 where bubbles
are present or where the tips of the switch may be out of the liquid.
The GT10 flow switch is designed for us in gas applications. For best results, avoid installing the GT10
where it may be submersed in liquid.
Always install the Viton gasket with all versions of the FT10‐__2_. The G threaded version will not seal
unless the gasket is properly installed.
The two temperature probes (tips) must always be perpendicular to the flow (see the flow at the same
time).
