General introduction
TBS glass plate liquid level gauges are level measuring instrument. Upper and lower needle switches and indicating equipments are their main components. Fluid flows via switch into the indicating equipment, then the liquid level will display clearly viewed through the range of effective light transmission. And on that basis, we have developed double color glass sheet liquid level gauges, defrost glass sheet liquid level gauges and steam thermal glass sheet liquid level meters to adapt to different places and different conditions.
About sight glass plates's glass quality, only borosilicate glass is used. The connection to the process is generally made with valve heads with single or double isolation. Drain valves enable the sight glass indicator to be emptied and are fitted to the lower flange face. If necessary, a vent valve can be fitted at the top.
