Parameters (HART)
1.7: Level damping (F = 1 s)
Damping of level in s
Set the damping of the level value in seconds. It acts on the analog output, the limit value
monitor and the local display. For damping of the sensor signal, set Parameter 4.2.3.1. For
slow moving solids applications, use a value of 500.
1.8: Application Type (F - Liquid [process])
Use of the vessel
Select Silo1 (solids) for tall, narrow silos. Select Silo 2 (solids) for large diameter silos,
typically used for cement. In most cases, you set one of the pre-specified applications.
The user vessels may adopt configurations which deviate from the factory settings.
These are designed for special applications loaded at the factory or by service personnel.
Additional Parameters
2. Display
2.1: Multi-display (F = level in m
Signal to noise ratio in db)
Display of two measured values. Values are determined in Parameter 4.5.1.1 (Line 1 Local)
and in Parameter 4.5.1.4 (Line 2 Local).
2.2: Level (F = m)
Current level of measured medium (set unit using Length Unit in Auto-Setup)

Note: The following parameters cannot be accessed when you set a user vessel:
Parameter 4.2.2.2 (Surface), Parameter 4.2.2.5 (Filling Speed), Parameter 4.2.2.6
(Reflectivity), and Sensor Parameters 4.2.3.1 (Sensor Damping), 4.2.3.2 (Multiple
Echoes), 4.2.3.3 (Echo Motion), 4.2.3.4 (Window Tracking), and 4.2.3.5 (Tank Empty
Detect). However, the parameters that remain under 4.2.2.x will be renumbered. See
page 32 for more information on parameter renumbering.
