Index
Number Parameter Description
33 DISTANCE Distance from the tank reference point (normally the
lower side of the flange) to the product surface
34 SIGNAL_STRENGTH Amplitude of the echo from the product surface. A high
value indicates a good reflection by the surface
35 SIGNAL_STRENGTH_UNI Signal strength unit
36 ANTENNA_TYPE Antenna type on the device (see Table C-7 )
37 TCL Tank Connection Length. Electrical distance between
the transmitter's reference point and the microwave
unit. Only for user defined antennas.
38 PIPE_DIAMETER Still-pipe inner diameter, see Tank geometry .
39 HOLD_OFF_DIST Hold Off Distance defines how close to the gauge’s
reference point a level measurement is accepted, see
Tank geometry .
40 ANTENNA_SIZE Still-pipe Array antenna size
41 OFFSET_DIST_G Gauge Reference Distance (G), see Tank geometry . Use
the Distance Offset (G) if a reference point other than
the lower side of the device flange is required.
42 TANK_HEIGHT_R Tank Reference Height (R) is defined as the distance
between the upper reference point and the lower
reference point (zero level). See
Tank geometry .
43 BOTTOM_OFFSET_DIST_C Minimum Level Offset (C) defines a lower null zone
which extends the measurement range beyond the
Zero Level Reference Point down to the tank bottom.
See
Tank geometry .
44 CALIBRATION_DIST Calibration Distance is by default set to zero. It is used
to adjust the level measurement so that measured
levels match hand dipped levels. See
Tank geometry .
45 TANK_SHAPE Tank Type (see Tank shape and Table C-9 ). Optimizes
the 5900S for various tank geometries.
46 TANK_BOTTOM_TYPE Tank Bottom Type. Optimizes the Rosemount 5900S
for measurements close to the tank bottom. See
Table
C-10 .
47 TANK_ENVIRONMENT Tank Environment. See Environment . Mark the check
boxes that correspond to the conditions in your tank.
For best performance you should not choose more
than two options. See
Table C-11 .
48 TANK_PRESENTATION Tank Presentation. See Table C-12 .
