I am using the exact $39 timer I suggested a few pages ago, same principle that according to Mr Phelps would not work, I use an $8 sensor from Digikey to sense a magnet at each of four locations (home position)to trip the timer,reducing the number of magnets to just two would do exactly what MitchM required, the timer is set for around 7 seconds, it can be expanded to 8 hours if required.

Actually my comments where based more on clarification and trying to understand exactly how the system would work and to be sure it would work. I made it clear exactly what would be needed to make the system reliable and if you read the thread it was you who failed to provide the information I asked for, I actually repeated questions multiple times.

I'm also a mechanical engineer who works in automation of manufacturing equipment but I do however appreciate your efforts to drag my name through the mud. In the past I've installed half a dozen of your units on clients tanks based on my recommendations as well as recommended them to many others when the application fits. I won't be doing that anymore.

It appears you have a very short memory, on at least 5 occasions you said it wouldn't work, and if it did it would be way more than $500, I told you how it could be done and again you disagreed, as you do on many occasions when we have been in a similar discussion, I showed you the video which proves my initial statement.

When I need a load sensor or advice on load sensors I will call you , when you need advice or info on OM you call me, just because you cannot figure out how to make it work for $39 doesn't make it impossible.

Actually it wasn't until post 55 that you finally managed to confirm the timer waits for a decay in the signal. Every other time you simply stated it works without explanation which is why I had to repeat my questions and concerns so much. I also always said it may not work if... and had to fill in the blanks based on the best assumptions I could make with the limited information provided, never did I flat out say it wouldn't work. My intent was to help you make a reliable system by asking a few simple questions and making some simple suggestions not to prove you wrong. My memory is fine but your reading skills and attitude could use some work.

It also still makes little sense to invest in an OM for this flow setup, a second pump will cost the same and produce better results.
