Stator cooling water conductivity?

[frankiee]

For Demin water stator cooling system
Why is the conductivity lower coming back from the generator then going to the generator.
Going to gen after HX and IX is about 0.13 micro Siemen/cm
Coming back from gen is about 0.5 micro Siemen/cm

Temp coming back is about 60 degree C
Temp going to gen is about 47 degree C

Original post had an error

I meant to say coming back from generator it is about 0.05 micro Siemen/cm

I would suspect calibration/measurement error first.

Frankiee:

The conductivity of metals usually decreases with rising temperature. With water it's the other way around. If the water temperature goes up, the conductivity goes up as well.
