Operation in zones of severe electrical interference:
The measuring device complies with the general safety requirements in accordance with EN 61010, the EMC
requirements of IEC/EN 61326, and NAMUR recommendation NE 21/43.
Note!
For cable specifications for hazardous area devices please see the additional Ex documentation.
Power consumption AC: 85 to 260 V = 18.2 W ; 20 to 55 V = 14 W ; (including sensor)
DC: 8 W (including sensor)
Power supply failure Lasting minimum 1 power cycle
• EEPROM/HistoROM T-DAT saves measuring system data if the power supply fails
• HistoROM S-DAT is on exchangeable data storage chip with sensor specific data (pipe type, nominal diam-
eter, serial number, flow conditioner, zero point, etc.)
• Totalizer stops at the last value determined
Potential equalisation No measures necessary
For devices in hazardous areas please refer to the additional Ex documentation
Performance characteristics
Reference calibration
conditions
• Accredited according to ISO/IEC 17025
• Tracable to National Standards
• Temperature controlled to within ±0.5°C (± 0.9°F) at atmospheric pressure and humidity controlled
Maximum measured error Flanged version:
±1.5 % of reading for 100 % to 20 % of full scale at reference conditions
±0.3 % of full scale for 20 % to 1 % of full scale at reference conditions
Insertion version:
±1.5 % of reading plus ±0.5 % of full scale
Note!
• Calibration gas is normally air at reference calibration conditions and with a fully developed flow profile.
• On site performance is dependant on the standard of installation.
Repeatability 0.5 % for velocities above 0.2 m/s (0.65 ft/s)
Response time Typically less than 2 seconds for 63 % of a given step change (in either direction).
