Working standards

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)
