Installation Scope
This section describes how to install the Fox Thermal model FT3 Flow Meter and how to get started.
Installation methods will vary according to the ow meter type (insertion or inline).
For Insertion Types:
1. Determine lateral position on the pipe.
2. Determine radial position of probe if moisture or condensation present in the gas.
3. Sensor installation depth.
4. Sensor orientation in relation to sensor length and direction of ow.
5. Proper tightening of compression tting for mounting meter.
For Inline Types:
1. Determine lateral position on the pipe.
2. Flow body orientation in relation to direction of ow in pipe.
3. Proper tightening of compression tting.
Installation procedures must be performed using a combination of the end user’s best engineering
practices, in compliance with local codes, and with manufacturer’s recommendations.
General Precautions
The following general precautions should be observed:
1. Exercise care when handling the ow meter to avoid damaging the probe, sensor or
enclosure.
2. Close any unused conduit openings in the enclosure with plugs certied for your
application.
3. The enclosure cover must be closed except during conguration or during installation.
4. Mounting FT3 in direct sunlight can cause the temperature inside the enclosure to increase
beyond design limits, resulting in failure of LCD display and reduced component life. It
is recommended that a sunshade be installed to avoid direct sunlight (see maximum
enclosure operating temperature specication).
5. Ensure the ow direction indicator points in the direction of ow.
6. Do not install the FT3 enclosure near an igniter, igniter-controller or switching equipment.
7. Do not install an external power supply in a cabinet containing an igniter controller or
switching equipment.
8. For accurate ow measurement, review ow meter placement instructions before
installation to ensure a proper ow prole in the pipe.
9. For safety reasons, Teon ferrules are only appropriate for applications with pressures of 60
psig or less. At higher pressures, use of a Teon ferrule risks unwanted probe movement
or ejection of the probe from the pipe. For all applications above 60 psig, the standard
stainless steel ferrule is required.
