Lasting min. 1 power cycle:
• EEPROM saves measuring system data if power supply fails
• HistoROM S-DAT: exchangeable data memory which stores the data of the sensor (nominal
diameter, serial number, calibration factor, zero point, etc.)

Performance characteristics

To DIN EN 29104 and VDI/VDE 2641:
• Fluid temperature: +28 °C ± 2 K
• Ambient temperature: +22 °C ± 2 K
• Warm-up time: 30 minutes
Installation:
• Inlet run >10 x DN
• Outlet run > 5 x DN
• Sensor and transmitter grounded.
• Sensor centered relative to the pipe.
• ± 0.5% o.r. ± 1 mm/s (o.r. = of reading)
• Optional: ± 0.2% o.r. ± 2 mm/s
Supply-voltage fluctuations have no effect within the specified range.
