Additional technical data

10.1.1 Input
The measured variable is the distance between the reference point (see Fig on → ä 14) and the
product surface.
The level is calculated subject to the empty distance entered (E, see Fig. on → ä 100).
Alternatively, the level can be converted by means of linearization (32 points) to other variables
(volume, mass).
10.1.2 Output
• FOUNDATION Fieldbus (H1):
– signal coding: Manchester Bus Powered (MBP); Manchester II
– data transmission rate: 31.25 KBit/s, voltage mode
Error information can be accessed via the following interfaces:
• Local display:
– Error symbol (→ ä 35)
– Plain text display
• Current output, failsafe mode can be selected (e.g. according to NAMUR recommendation
NE 43).
• Digital interface
The Levelflex M linearization function enables conversion of the measured value to any desired
length or volume unit, mass or %. Linearization tables for volume calculation in cylindrical tanks are
preprogrammed. Any other tables with up to 32 value pairs can be input manually or semi-
automatically. The creation of a linearization table with the FieldCare is particularly convenient.
