    Water resistance

    Anyone know what the proper resistance should be for the
    water in a steam boiler using a PS-802 (McDonnell&Miller)
    probe type lwco? Instructions mention that conductive liquid
    is required. Would it be better to use a float type lwco in
    a steam boiler, rather than the probe type?
    Thanks for now, Mike Lampkin

    water conductivity

    Mike, water is a conductive liquid. Probe/electronic LWCO's work great and are less troublesome from a maintenance standpoint. Just make sure you make cleaning the probe annually part of the boiler service tasking. They do get dirty and can fail if too much crud gets built up on the probe.
