Technical data Micropilot FMR20 HART
64 Hauser
Bluetooth® wireless technology (available as an optional extra)
The device has a Bluetooth ® wireless technology interface and can be operated and
configured via this interface using the SmartBlue app.
• The range under reference conditions is 25 m (82 ft)
• Incorrect operation by unauthorized persons is prevented by means of encrypted
communication and password encryption
• The Bluetooth ® wireless technology interface can be deactivated
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 device's linearization function allows the user to convert the measured value to any
units of length, weight or volume. In DeviceCare and FieldCare, there are pre-programmed
linearization tables for volume calculation in vessels.
Pre-programmed linearization curves
• Horizontal cylindrical tank
• Spherical tank
• 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.
14.3 Performance characteristics
Reference operating
conditions

Maximum measured error Typical data under reference operating conditions: DIN EN 61298-2, percentage values in
relation to the span.
Output, digital
(HART, SmartBlue (app))
• Sum of non-linearity, non-repeatability and hysteresis: ±5 mm (±0.2 in)
• Offset/zero point: ±4 mm (±0.16 in)
Output, analog
Only relevant for 4-20mA current output; add error of the analog value to the digital value
