Need suggestions for a part

R_Phoenix

Hello all.

 

I am looking for the best option to detect when water is in a pipe. In a nut shell I 'm looking for a way to know when water is available inside a 3/4" pipe.

 

I thought of a pressure switch but I can't seem to find anything that is simple and in expensive and also there won't always be pressure on the switch, for instance when the water is flowing threw the pipe.

 

Then I thought of a flow meter, but again the water won't always be flowing to detect motion.

 

Now I am thinking of reading the capacitance/resistance of the water. I have a few options but I was wondering what else might be out there that I haven't stumbled on yet.

 

Thanks everyone.

  • Have you considered using a piece of wire and a strain gage?  Once you set up the wieght of the pipe empty, you should be able to measure the added weight of any water to a fair degree of accuraccy.

     

    Just a thought.

    PS, you might also get by with a microswitch.  It depends on how sensitive you need the indicator to be.
