  • Page 18: General

    Model FT4X Installation Installation Scope This section describes how to install the Fox Thermal Model FT4X Flow Meter: For Insertion Types: 1. Determine lateral position on the pipe 2. Verify sensor installation depth 3. Determine sensor orientation in relation to sensor length and direction of flow 4.

  • Page 19: Lateral Placement

    Model FT4X Installation Instructions for Flow Meter Lateral Placement Install the Model FT4X flow meter so that it is far enough away from bends in the pipe, obstructions, or changes in line sizes to ensure a consistent flow profile. See Fig. 2.1 below for your meter type.
  • Page 20 Model FT4X Installation Tilt Installations - Moisture in the Gas or Condensation Tilt Installations - Moisture in the Gas or Condensation Tilted variations on installations help prevent moisture and condensation from forming Tilted variations on installations help prevent moisture and condensation from forming on the sensor and disrupting accurate flow measurement.

  • Page 21: Welding Branch Outlet

    Model FT4X Installation Welding NPT Female Fitting to Pipe The probe of the FT4X must be installed perpendicular in the pipe to measure flow accurately. Use the following steps to ensure that the 1" NPT female fitting is correctly welded to the pipe. Directions: 1.

  • Page 22: Installation Depth

    Model FT4X Installation Installation Depth The installation depth of the sensor in the pipe is dependent on the pipe size. To get the most accurate reading, proper placement of the sensor window within the pipe is necessary. As shown in Fig 2.4, the end of the sensor window should be 0.73" (18.5 mm) past the center line of the pipe.

  • Page 23: Orientation

    Model FT4X Installation Rotating the Enclosure The Model FT4X enclosure has been designed to allow the enclosure to rotate for optimal viewing of the display. To rotate the enclosure, first loosen the two set screws near the Flow Direction Indicator. Then rotate the enclosure into the desired position and tighten the set screws.
  • Page 24 Model FT4X Installation Changing the Orientation of the FT4X Display The display can be rotated in 90° increments for optimum viewing of the screen. First, open the enclosure by unscrewing the enclosure cap and loosen the two captive screws to open the display assembly.

  • Page 25: Mounting Instructions

    Model FT4X Installation Mounting Instructions - Compression Fittings The Model FT4X is mounted through a 0.781" hole and a 1-inch female NPT branch outlet in the customer's pipe. Insertion style flow meters are not designed for use in pipes smaller than 1½".

  • Page 26: Retractor Installation

    Model FT4X Installation Installation of a New Retractor Assembly 1. Remove collar clamp from probe using a 3/16" Hex Key. 2. Remove meter probe from retractor assembly and leave the ball valve open. Keep the collar spacer on the probe so it is not misplaced. 3.
  • Page 27 Model FT4X Installation 4. Carefully slide the probe through the retractor assembly and through the hole to see if there is interference by touching the pipe wall with the end of the probe on the far side or until the probe cannot go deeper.
  • Page 28 Model FT4X Installation 5. Using the equation (L + D/2 + 0.73") from Figure 2.11, calculate the insertion depth and mark on the probe while measuring from the end of the probe. 6. The Retractor Clearance table of Figure 2.11 lists the space required to remove the meter from the retractor.
  • Page 29 Model FT4X Installation 7. Insert probe back into the retractor to the depth mark and hand-tighten the compression fitting. Make sure collar spacer is in place on the probe. 8. Verify that flow direction indicator is in line with pipe and in the direction of flow. Fig.
