INSTALLATION MT100 Multipoint Flow Meter
Install Flow Element
Duct Flange Installation (MT100M)
Install the duct mount flow element assembly as appropriate to its configuration. Refer to APPENDIX A, page 97 for configuration
information specific to the unit’s serial/tag number.
Follow these steps to install the flow element.
1. The exact placement of the flow element is typically predetermined at the time of order. Use hole pattern and hole sizes as shown in
Figure 4, page 9 to drill holes for flow element duct mount flange. On opposite side of duct use hole pattern and hole sizes as shown
in Figure 5, page 10 to drill holes for flow element duct mount end support.
End support is secured to duct via anchor nuts supplied in end support mounting kit.
2. Using supplied end support mounting kit hardware, install flow element’s end support as shown in Figure 5. Loosely torque end
support securing bolts (6 ea. 5/16-24UNF x .875 lg).
3. Carefully place flow element in process duct with flow arrow pointing in direction of process media flow and with reference flat parallel
to flow. Insert end of flow element assembly standpipe into end support sleeve.
4. Using supplied duct flange mounting kit hardware, install flow element to process duct as shown in Figure 4. Using star pattern bolt
torque sequence shown in Figure 4 gradually torque duct flange securing bolts (6 ea. 5/16-24UNF x .875 lg) with final bolt torque at
10 ft-lbs (13.6 N-m).
5. With flow element assembly standpipe captured within end support sleeve loosely install 1/2-13UNF x 2-inch long bolt (included in
optional end support mounting kit) into end support sleeve, engaging flow element standpipe (see Figure 5). (Note: Use the alternative
installation method that uses a reinforcement plate if the supplied anchor nuts are not adequate for the application.) Using star pattern
bolt torque sequence shown in Figure 4 gradually torque end support securing bolts (6 ea. 5/16-24UNF x 1.0 lg) with final bolt torque
at 10 ft-lbs (13.6 N-m).
6. Torque end support sleeve bolt to 37 ft-lbs (50.2 N-m).
For the alternative installation method, the reinforcement plate with drilled, tapped holes is customer-supplied. Refer
to Figure 6 and Figure 7. Longer bolts (typically 1-inch long) may be needed when the reinforcement plate is used.
