Q1
Calibration gas
Methane (quality 4.5) with automatic injection for 1-point calibration. Nitrogen,
methane, calibration gas mixture H2-11K and a binary mixture of 5% CO2 in
metane(formely L1-8K) for manual activated basic calibration.
Operating pressure/consumption
Standard configuration with low-pressure controller and integrated safety shut-
off/safety relief valves
Inlet pressure: 0,5 to 5 barg, 30 l/h
90 % response time (T90)
Approx. 20 to 60 seconds (in case of standard configuration, depending on
bypass flow rate (Optional 10 sec.)
Accuracy in the range of 34.2 to 45.0 MJ/m3
Hs=GCV: < 0.4 %(relative), s: < 0.8 %(relative), CO2: < 0.2 % (absolute).
Reproducibility:
Hs=GCV: < 0.1 %(relative),
s
: < 0.1 %(relative), CO
2
: < 0.1% (absolute).
