Verify Sensing Element Flow Direction and Placement Orientation (Level Application)
If the sensing element is side-mounted on the process vessel, then the surface marked with direction arrows should be vertically oriented.
If the sensing element is top- or bottom-mounted on the process vessel, the orientation of the surface marked with direction arrows does not
matter.
Install the Sensing Element
Male NPT Mounting
When mounting the sensing element to the process pipe, it is important that a lubricant/sealant be applied to the male threads of all con-
nections. Be sure to use a lubricant/sealant compatible with the process environment. All connections should be tightened fi rmly. To avoid
leaks, do not overtighten or cross-thread connections. See Figure 2-1 for proper mounting.

Flange Mounting
For fl ange mounted sensing elements, attach the process mating fl ange with care. The correct orientation of the sensing element must be
maintained to ensure optimum performance or calibration. See Figure 2-2.
