coolant loss

I have been experimenting with some mods to my cooling system and trying out a few ideas. After a recent mod I took a short drive on a hot day to test it out. I had a complete loss of coolant when a hose blew off. It was the one going down from t-stat to under floor and came off down low, open pointing towards the ground. Needless to say, if a pump is moving say 30 gallons per minute and there are only about 3 gallons in the system, it didn't take long to empty the entire system - and I didn't notice when it blew out the bottom of the car. The temperature gauge measures the temp of the coolant flowing past it. No coolant, no change in temp reading - until the engine got really HOT. So I started looking for a loss of coolant sensor. Found a Longacre 40141 that is a kit with sensor and light for $25, I ordered one and will update after install, But, I think it might be possible to do it for zero bucks. If you still have the stock idiot lights in your dash and the stock oil pressure warning light sensor, I think it might work if the sensor is screwed into water jacket. Depends on what pressure the switch works. Anyway, I urge all to consider adding such a device. I am still not sure if my engine has been damaged or not, but a loss of coolant warning light might have stopped me from driving as far as I did with no coolant
