Hello ,
I am building a 57 inch model of a steam boat. The boiler is 6 inch and runs at 50 PSI and a temperature of 280 o F. There are two separate steam engines that consume allot of water.
My mission is to come up with a RELIABLE system that will maintain water level and prevent burning out a very expensive boiler.
Was thinking of using three stainless probes immersed in the water at two different levels. The third probe would provide constant voltage. Some damping may be required . The difference between the low and high level is about an inch.
I have just started with Arduino. Electronics is weak , still work with ladder logics :).
Would appreciate any suggestion.
Thank you for your time .

What about a mechanical float that is either connected to a water valve or a pot? If the pot is used as the pivit for the float it will give an analog signal depending on the level of the float.
Hello ,
Thanks for the Idea, this arrangment would expose much of the high pressure and high temperature to leakage.
Plan to use a high pressure low volume pump,5 liter/min,110 psi. 12 volt 3 amp.

Something like this

I imagine the main function of the Arduino would be to provide sensibly damped average readings.
