6 Level Measurement
6.1 Start-up with the Universal HART Communicator DXR 275,
Commulog VU 260 Z or Commuwin II
Function check The "Level linear", "Level cylindrical horizontal" and "Level manual" modes are selectable
via communication. In these modes, the current measured pressure value is
automatically converted to "%". To improve the display, other level, volume and weight
units can be selected using the "Unit after linearisation" parameter.
Your device can be checked for the advanced "level measurement" function as follows.
•
The sixth position of the order code has an M or N for the electronic version
Example: PMP 635-R 1 3L 1
M 1 A AF 1
•
The function "linearisation" (in line V3 of the operating matrix) can be selected.
•
Software No. given in V2H2:
– for devices with HART protocol: 6570
– for devices with INTENSOR protocol: 6950
