P001 Operation
Note
Default values are indicated with an asterisk (*) in the parameter tables, unless explicitly
described.
Sets the type of measurement required for the application. (This affects the local LCD only:
the primary variable for HART is controlled by P201.)
To measure how full the vessel is, select Level. The reading can be returned as level or as
volume:
●
for a level reading, ensure P050 is set to 0: the reading returns the distance from process
empty level (Empty) to the current level
●
for a volume reading, select a vessel shape at P050, and set volume parameters P051
toP055 as required
To measure how much space remains in the vessel, select Space:
●
Space returns a reading for the distance between current level and process full level
(Span)
To measure the distance from the reference point to the current level, select Distance. For
the reference point, see SITRANS Probe LR dimensions (Page 84).
Values
1 * Level returns material level referenced from Empty (process empty level). The
reading is returned in volumetric units if parameters P050 to P055 are set to ena-
ble this.
2 Space returns material level referenced from Span (process full level).
3 Distance returns material level referenced from the reference point. For the refer-
ence point, see SITRANS Probe LR dimensions (Page 84).
