    Hi,
    i found a device which could be used for auto topup purposes BUT
    it uses probes made of stainless to be inserted into liquid.
    You think these stainless probes will last some time or not?

    they call it a 'liquid level relay' and it uses 3 probes to either fill or empty a 'body of liquid'.
    cost R255 and probes cost R48 each.

    It depends, you get different grades of stainless steel, there is a special grade of stainless that can be used in saltwater.
