The following formulae are used to calculate the K
1
and K
2
factors
needed to convert the current or frequency into a flow rate:
Full scale K factor K
1
K factor K
2
10 m/s
K
1
= 100
K
fitting
K
2
= 20
3*K
fitting
5 m/s
K

= 200
K
fitting
K
2
= 40
3*K
fitting
2 m/s
K

= 500
K

K

= 100
3*K
fitting
where K
fitting
= 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
fitting
with I in mA, K
fitting
in pulse/litre and Q in l/s.
