Power supply failure
• Lasting min. 1 cycle frequency:
• EEPROM saves measuring system data
• S-DAT: exchangeable data storage chip which stores the data of the sensor (nominal diameter,
serial number, calibration factor, zero point etc.)

Performance characteristics
Reference operating
conditions
To DIN EN 29104 and VDI/VDE 2641:
• Fluid temperature: +28 °C ± 2 K
• Ambient temperature: +22 °C ± 2 K
• Warm-up period: 30 minutes
Installation:
• Inlet run >10 × DN
• Outlet run > 5 × DN
• Sensor and transmitter grounded.
• The sensor is centered in the pipe.
Maximum measured error
• Current output: plus typically ± 5
μ
A
• Pulse output: ± 0.5% o.r. ± 1 mm/s
Option: ± 0.2% o.r. ± 2 mm/s (o.r. = of reading)
Fluctuations in the supply voltage do not have any effect within the specified range.

Inlet and outlet run
If possible, install the sensor upstream from fittings such as valves, T-pieces, elbows, etc. The
following inlet and outlet runs must be observed in order to meet accuracy specifications
(
