Lew, that's an interesting statement. What's unreliable about a well-designed float (e.g., http://x.co/KGoQ), or for that matter, the cycling pump that we were talking about? These seem like no-brainers. It's not like you're working with high-viscosity materials here; it's pretty well limited to water with maybe some oil and fuel mixed in.

OK, I can see conductivity as being of marginal use if the contacts get coated with oil; somewhat of a ditto for capacitance, although for slightly different reasons. What's the failure mode for ultrasonic or pulse radar? I can't imagine radar-absorbent foam being a common component of bilge water. :) -- OKOPNIK CONSULTING Custom Computing Solutions For Your Business Expert-led Training | Dynamic, vital websites | Custom programming 443-250-7895 http://okopnik.com http://twitter.com/okopnik _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://liveaboardonline.com/mailman/listinfo/liveaboard To subscribe send an email to [email protected] To unsubscribe send an email to [email protected] The archives are at http://www.liveaboardonline.com/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://liveaboardonline.com/mailman/listinfo/liveaboard To subscribe send an email to [email protected] To unsubscribe send an email to [email protected] The archives are at http://www.liveaboardonline.com/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
