L00-NRF590-14-00-08-yy-002
• Level sensor • level • Tank Ref Height
Level + Temperature
L00-NRF590-14-00-08-yy-003
• Level sensor
• Temperature sensor
(RTD or
HART device;
optionally with bottm
water probe)
• level
• temperature
Hybrid Tank Measuring System (HTMS)
HTMS + P1
L00-NRF590-14-00-08-yy-004
• Level sensor
• Pressure sensor
(P1, bottom)
• level
• density of the measured
medium (calculated)
•Tank Ref Height
• P1 Position
•Min HTMS
(minimum level at which HTMS
measurement is possible; should be
slightly above the position of the P1
sensor)
•local gravity
• vapour density
• air density
• P3 Position (only for the "HTMS +
P1,3" mode)
HTMS + P1,3
!
Note!
This mode should be
used in non-
atmospheric tanks (e.g.
pressurised tanks)
