Average temperature measurement with MRT
___________________________________________________________________________
Instruction manual VITO Page 22
Item Name Description
MO= Temperature element offset Format according to item LD (default: +000.0000 m).
The offset represents the distance from the tank zero level to the
lowest position of the MRT.
Note:
In case of ullage measurement, distance MO is taken from the
upper reference point.
MI= Switch hysteresis Format according to item LD (default: +000.1000 m).
The distance MI is a hysteresis around the switching point of the
temperature elements.
MP= Product immersion depth Format according to item LD (default: +000.5000 m).
The distance MP specifies the minimum required liquid level
above an element before it is selected for the average product
temperature calculation.
MG= Gas immersion depth Format according to item LD. (default: +000.5000 m).
The distance MG specifies the minimum required distance before
the resistance value of the longest element is taken in the
average gas temperature calculation
TU= Temperature status conversion
One character (default: ‘T’)
This item is used to indicate the temperature status character in
case of a reduced or not guaranteed temperature accuracy. This
is the case when the temperature status is:
• out of specified temperature range
• exceeding differential temperature range
• last valid level used
• manual level used
• level below lowest temperature element
If required, this item can be set to another character.
