4.2.1.3.2: Pipe Diameter (F = 100 mm) [Liquids]
Internal diameter of the stilling pipe
Value
4.2.2: Measuring Conditions
4.2.2.1: Application Type (F - Liquid [process])
Use of the vessel
Value
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
here. 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.
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.
4.2.2.2: Surface (F = wavy)
Surface structure of the measuring medium. Not displayed if a user vessel is selected in
Parameter 4.2.2.1.
Value
This parameter is not displayed when a user vessel is selected in Parameter 4.2.2. 1 . When
used with poorly reflecting measuring media, you may be able to improve measuring
results by setting a different surface structure here. If your measuring medium forms
waves more than 1 cm in height, you should select the wavy setting. The turbulent setting
is recommended for waves greater than 10 cm.
