Micropilot FMR20 HART
8 Endress+Hauser
Signal on alarm
Depending on the interface, failure information is displayed as follows:
• Current output
Alarm current: 22.5 mA (in accordance with NAMUR recommendation NE 43)
• Operating tool via digital communication (HART) or SmartBlue (app)
• Status signal (as per NAMUR Recommendation NE 107)
• Plain text display with remedial action
Linearization
The linearization function of the device allows the conversion of the measured value into any unit of
length, weight, flow or volume. When operating via DeviceCare and FieldCare, linearization tables
for calculating the volume are preprogrammed in the vessels.
Pre-programmed linearization curves
• Horizontal cylindrical tank
• Sphere
• Tank with pyramid bottom
• Tank with conical bottom
• Tank with flat bottom
Other linearization tables of up to 32 value pairs can be entered manually.
