The 249VS is installed directly on the vessel as shown in figure 4. The sensor mounts on the side of the vessel using an
NPS 4 flat face or raised face flange.
Because the displacer hangs inside the vessel, provide a stillwell around the displacer if the fluid is in a state of constant
agitation to avoid excessive turbulence around the displacer. For interface or fluid level applications, install a gauge
glass on the vessel.

CAUTION
If inserting the displacer into the vessel before attaching it to the displacer rod, provide a means of supporting the displacer
to prevent it from dropping into the vessel and being damaged.
Install the sensor wafer body on the vessel using the following procedure.
Attach the displacer to the displacer rod (see figure 5) before installing the sensor on the vessel.
1. Place a connecting flange gasket on the sensor assembly.
2. Install four line flange studs and nuts in the connecting flange at locations that correspond to the sensor mounting
lug locations.
