The MVT provides connection ports on the process flange as the
standard arrangement. Optional manifold blocks may also be specified.
Arrangements are described as follows:
 Standard Process Flange for MVT – Two process flanges
containing the connection ports are assembled to the differential
transducer. Port designations (L and H) are stamped on the body
between the flanges. Ports accept ¼-18 NPT pipe connections to 2-
1/8 in. centers for connection to orifice taps or a standard three-
valve manifold. These process flange connections are illustrated at
the top of Figure 2-5.
 Four bolts and nuts hold the two process flange assemblies in place.
When you remove the bolts, you can reposition the flanges so that
the connections can emanate from the front, rear or bottom of the
transducer. Take care not to damage the sensor module assembly
during this procedure. Once you position the flange, tighten the bolts
in an alternating sequence to about 20-30 foot-pounds of torque.
