1. Driver rod length is the perpendicular distance between the vertical centerline of the displacer and the horizontal centerline of the torque tube. See figure 12. If you

cannot determine the driver rod length, contact your

2. This table applies to sensors with vertical displacers only. For sensor types not listed, or sensors with horizontal displacers, contact your Emerson sales office for the

driver rod length. For other manufacturers' sensors, see the installation instructions for that mounting.
