Figure C-15. Minimum
requirements.
If a 5300 Series transmitter is ordered from Rosemount together with a 9901
Chamber, these space requirements are met. If an existing chamber is used,
which does not meet these space requirements, a spool piece can be added.
For an installation with a spool piece, it is important to make sure that the
reference reflector and the spool piece do not have the same length. The
spool piece needs to be at least 2 in. (50 mm) longer or shorter.
Installation Setup It is important that the vapor compensation function is calibrated after
installation. Before calibration:
• The surface level must be at least 19.7 in. (0.5 m) below the end of the
reflector (It is recommended to empty the pipe/chamber.)
• Perform the calibration at ambient pressure and temperature
conditions, i.e. when the vapor dielectric constant is close to 1.0
Level: 100%
Level: 0%
Measuring range:
min 12 in. / 300 mm
