Flow sensor mayhem

[dr pepper]

Thought I'd share this.
I put together a web based dashboard for a cooling system for water cooled brakes on one of the machines I maintain, temp and fow is monitored for 2 brakes and displayed on gauges and a graph.
I had issues with the flow sensors, one worked but the other triggered both sensor readings, after ages fault finding I found that the magnet in one sensor was triggering the hall sensor in both flow sensors, I had them both bolted together to look nice & neat, now they are apart they work fine.
Sounds simple once found, but it wast so obvious beforehand.

Go figure? Who would have thought? Yeah, sounds simple once found but I never would have thought to look for that. While I doubt I will ever encounter that thanks for sharing, gives pause for thought.
