Characteristic diagram K-Factor – K-Factor
This function is used for adaption of the characteristic diagram up to formula
Qkorr = Qist * K;
Qist -measured flow;
Qkorr -corrected flow;
K - absolute term (multiplicative)
It is used if flow conditions have changed referring to the original calibration
Advice:
This function is protected due to a separate Code (KO_Code). If the code is required
please ask
For it at the manufacturer
Characteristic diagram dynamical offset – Dynamical Offset
This function is used for adaption of the characteristic diagram up to formula:
Qkorr = Qist + DynOffset*(Qist/QmaxPhys);
With: Qist -measured flow;
Qkorr -corrected flow;
QmaxPhys - max. flow in pipe at v=5m/sec
DynOffset - absolute term (additive)
Advice:
This function is protected due to a separate Code (KO_Code). If the code is required
please ask for it at the manufacturer
Integration Time
The DU06 needs for one flow measurement approx. 80 ms. It calculates the indicated flow
out of a minimum of 10 und max. 100 measures. This means an adjustment range of the
Integration Time
of 0,8 sec until 8 sec. The average value is detected by the method of
moving exponential average value.
