High Pressure Steam Applications
Considerations Saturated steam under high
pressure can influence radar
level transmitter measurements.
Rosemount 5301 with Dynamic
Vapor Compensation (DVC) will
automatically compensate for
this and maintain the level
accuracy.
Considerations for DVC:
• A Single lead rigid HTHP
probe with a reference
reflector for vapor
compensation must be used
(probe type 4U, 4V)
• Mount in a 2, 3, or 4-in
bypass chamber with
flanges appropriately sized
for the pressure and
temperature of the
application
• Use a centering disk to
keep the probe centered in
the chamber see “Chamber
/ Pipe Installations” on
page 34
• Probes up to 13.1 ft (4 m) in
length are supported
• Minimum measuring range is 12 in. (300 mm)
• DVC requires a minimum distance from the flange to the surface level in order to measure the
change in the vapor dielectric constant. If the level rises within this area, the unit switches over to
static compensation, using the last known vapor dielectric constant
For more information, refer to the High Pressure Steam Applications Technical Note (Document No.
00840-0100-4530)
(1) Reverse polarity protection.
(2) Final rating may be lower depending on flange and O-ring selection, See “Tank Connection and Probe” on page 31.
Level: 100%
Level: 0%
Minimum distance for dynamic
compensation up to level 100%:
17.3 in. (440 mm) for probes <6 ft. (2 m),
28 in. (710 mm) for probes >6 ft (2 m)
Minimum measuring range:
12 in. (300 mm)
If a spool piece is
used, it is
important that the
reference reflector
is not positioned
where the spool
piece connects to
the chamber.
