The following formulae are used to calculate the K

and K

factors
needed to convert the current or frequency into a flow rate:
Full scale K factor K

where K

= K factor of the S020 fitting used
Example:
If the full scale of the device is set to 5 m/s, the value of the current
output will be:
I = 40 Q + 4
3*K

with I in mA, K
fitting
in pulse/litre and Q in l/s.
