1 Standard (order code for "Calibration flow", option 1 "Operable flow range 30 : 1")
2 Optional (order code for "Calibration flow", option 2 "Operable flow range 100 : 1")
Accuracy of outputs
o.r. = of reading
The outputs have the following base accuracy specifications.
Current output
Accuracy ±10 µA
Pulse/frequency output
Accuracy Max. ±100 ppm o.r.
o.r. = of reading; o.f.s. = of full scale value; abs. = absolute; T = medium temperature
Volume flow
±0.5 % o.r.
Methane
±0.5 % o.f.s. = ±0.5 % abs.
Temperature
±0.3 °C ± 0.0025 × T °C (±0.45 °F ± 0.0025 × (T – 32) °F)
• The response time depends on the configuration (damping).
• Response time in the event of erratic changes in the flow: after 1 000 ms 95% of the full
scale value.
