Installing in a tank with a nozzle or stand-off
Installation procedure
1. Use PTFE tape on the screw thread of the transmitter (Figure 3-3).
2. If the tank has a flanged nozzle or stand-off:
a. Attach the transmitter to a non-metal instrument flange using the threaded
connection. Tighten to a torque of 1.5 lb-ft (2 N-m) using the transmitter’s hexagon.
b. The instrument (accessory) flanges supplied by Emerson Process Management are
manufactured from PVC and are a full face design. Care must be taken when installing
to a raised face mating flange on the tank or vessel to prevent distortion of the PVC
flange by over-tightening the bolts.
c. Ensure the gasket is sitting correctly on the tank flange.
d. Lower the assembled transmitter and instrument flange onto the tank flange, and
secure with appropriate bolting to a suitable torque for the flanges.
If mating to a raised face flange (RF) on the tank nozzle or stand-off, tighten to a
maximum torque of 10 lb-ft (13.6 N-m).
3. If the tank has a threaded nozzle or stand-off:
a. Attach the transmitter to the nozzle/stand-off using the threaded connection.
b. Tighten to a torque of 1.5 lb-ft (2 N-m) using the transmitter’s hexagon.
Note
If the transmitter face does not protrude into the vessel, note the dimensions in
Table 3-1 on page 3-13 for Figure 3-3, and ensure that the nozzle/vessel weld is smooth
and free from internal weld beads or other projections.
