Prosonic Flow W
• Cable material made of PVC (standard) or PTFE (for higher temperatures)
• Cable length: 5 to 60 m (16.4 to 196.8 ft)
!
Note!
To ensure correct measuring results, route the connecting cable well clear of electrical machines
and switching elements.
Power consumption AC: < 18 VA (incl. sensor)
DC: < 10 W (incl. sensor)
Switch-on current :
• max. 13.5 A (< 50 ms) at 24 V DC
• max. 3 A (< 5 ms) at 260 V AC
Power supply failure Lasting min. 1 power cycle:
EEPROM and T-DAT save measuring system data if the power supply fails
Potential equalization For potential equalization, no special measures are necessary. With regard to devices suitable for
potentially explosive atmospheres, please refer to the information in the Ex-specific supplementary
documentation.
10.1.6 Performance characteristics
Reference operating
conditions • Fluid temperature: +20 to +30 °C
• Ambient temperature: +22 °C ± 2 K
• Warm-up period: 30 minutes
• Sensors and transmitter are grounded.
• The measuring sensors are correctly installed.
Maximum measured error At a flow velocity of > 0.3m/s (1 ft/s) and a Reynolds number > 10000, the following error limits
of the measuring device are guaranteed:
!
Note!
The Prosonic Flow 93C Inline sensor is also available without factory flow calibration. The error
limits without calibration are ±1.5 % o.r. ± 3 mm/s
Repeatability ±0.3 % for flow velocity > 0.3 m/s (1 ft/s)
Nominal diameter Guaranteed error limits of the device Report
DN 300 to 2000 (12 to 80") ±0.5 % o.r. ± 3 mm/s Factory measurement report
