qbig works with parallel operated standards in two groups. There are only two types of different turbine meters in the standards
- In Group 1 are 5 turbine meters in DN100 Qmin=13m3/h – Qmax=480m3/h
- In Group 2 are 4 turbine meters DN250 Qmin=130m3/h – Qmax=4800m3/h
- Comparsion of the standards directly against each other
- With the standards in group 1 it is possible to check one standard meter in group 2 up to a flowrate of 2500m3/h
- Continuous online check of the standards with ultrasonic gas flowmeter
- Calibrated to the european harmonized reference value (HRV)
