Will the glass of water gauge explode in summer?
Instead, in winter, water meters can be frozen and burst because the water is below 4 degrees and freezes after expansion.
In many parts of our country, winter can reach 5 degrees below zero, which is the freezing point temperature of a blasting water meter.
Summer does not explode, water meter can be 90 degrees high temperature, water glass is 500 degrees higher temperature
