I personally don’t bother with low coolant alarms, I just run engine watchdog head temp monitors. No false positives and they tell alert me to engine temp higher than normal - regardless of the reason.

That's good to know. I thought I was buying a head mounted temperature gauge with low coolant alarm the other week but ended up with a head mounted temperature gauge and no oil alarm

This thread did entice me to by a cheap capacitive proximity sensor of Ebay to play with on the coolant tank after a bit of googling on this site.
