Re: [mh] Liquid Level Sensor recommendation

[David H. L. Jr. <dh...@dl...>]

    If it has a visual gage you could set one or more optical sensors at 
points you wish to monitor and then read them any number of ways. 
probably for only a few bucks.

    `You could also check for interesting ideas from back issues of 
Circuit Cellar, or maybe Nuts & Volts.
    It may require trying to think of how to creatively use some widget 
in a way different from intended.
    Ultimately you are balancing your own time and effort against 
commercial cost, but I can think of alot of differnet ways to create a 
level sensor, and even more if all you need is a single almost out of 
fuel sensor.
