Flow Sensor Selection
To select the flow sensor package that best fits your requirements,
consider these application parameters:
1. Determine Installation Fitting Type – fittings are available for a
variety of piping materials.
2. Determine Installation Fitting Size – identify the HIGHEST
anticipated flow rate which would occur regularly thru EACH tank
of a single/multiple tank network. Match this value against those in
the MINIMUM and MAXIMUM FLOW column of the Flow Rate
Range Table to find the corresponding installation Fitting Pipe Size.
3. Verify Temperature/Pressure Operating Range – the maximum
operating pressure for the XLF series flow sensor is dependent on
the measured fluid temperature and type of installation fitting. Refer
to the Temperature/Pressure Graph for operating range. Refer to
OPTIONS paragraph for applications requiring a higher
temperature/pressure rating.

Options
Installation Fitting Service Plug:
Allows resumption of flow after depressurization and removal of flow
sensor element.
Wet Tap Assembly:
Provides a safe and fast method of removing a flow sensor element
without shutting off flow and pressure.
(Maximum Pressure – 100 psig @ 68
0 F; Maximum Temperature – 140°F
@ 25 psig)
High Temperature/Pressure Applications:
Contact factory for pressures up to 1,500 psig and temperatures up to
300°F for stainless steel flow sensors.
