Grundfos Magna 3

I have a customer that has a magna 3 Delta p circulator in his system.
It has been intermittently having issues where the sensor apparently is bad.
I have the sensor but cant find any info available as to if it is a wet tapping that it fits into or a dry one.

    FYI... Its wet.
    Pulled it out and got a squirt.
    oh well.
    I know now.

    Sorry I missed this. FYI the sensors can get dirty in extreme conditions, they are very easy to wipe clean if necessary.

    The system is a good sized one.
    Im sure a good flush w/ some Fernox would be a good idea.... and some inhibitor after.
