Liquid water content indicator’s design provides user a correct manner to ensure the quality and water content of refrigant in system. Through wide – angle sight glasses, we can see the refrigant in system and it is easy to see the bubble or flash evaporation gas in system so that we can Rnow if the refrigant quatity needs to be filled.
The indicator componeents in the enter of sight glasses are highly alert to the water’height and can change colour graducally as the water quantity in system changes.
