Parameters (HART)
4.2.1.3: Pipe Diameter (F = 100 mm)
Internal diameter of the stilling pipe
4.2.2: Measuring Conditions
4.2.2.1: Application Type (F - Liquid [store])
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
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. the
following Parameters cannot be accessed when you set a user vessel: Parameter 4.2.2.2,
Parameter 4.2.2.5, Parameter 4.2.2.6, Parameter 4.2.3.1 and Parameter 4.2.3.5.
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.
This parameter is not displayed when a user vessel is selected in Parameter 4.2.2.1. In the
case of poorly reflecting measuring media, you may be able to improve the 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 > 10 cm. The default setting is the “wavy” surface
structure.
