Technical data at a glance

10.1.1 Input
The distance D between the sensor membrane and the product surface is measured.
Using the linearisation function, the device uses D to calculate:
• level L in any units
• volume V in any units
• flow Q across measuring weirs or open channels in any units
Sensor Maximum range in liquids
FMU 40 5 m
FMU 41 8 m
FMU 43 15 m

The actual range is dependent on the measuring conditions. Refer to Technical
Information TI 365F/00/en for an estimation.
10.1.2 Output
4 ... 20 mA with HART protocol
• Error symbol, error code and plain text description on the on-site display
• Error code via HART communication
• Current output (configurable)
10.1.3 Auxiliary energy
• Cable gland M20x1.5 (recommended cable diameter 6 ... 10 mm)
• Cable entry G½ or ½ NPT
• Loop-powered HART: 14 ... 36 V (depending on output current)
