Is there a chemical feeder on the market that can sense glycol concentration and automatically feed. Any ideas appreciated. Thanks
The chemical people normally mix the correct amount of glyco and water in the tank. And use the pump to force the mixed solution into the system when it is low. As the tank is low, they fix the leak and mix another full tank. That's is the best way.
Remember, glyco system does not have a fresh water make-up station/valve like the conventional system you normally see.
