Fluidyne engineers continuous research, development and experimental studies on alumina-borosilicate composition has made the tempered glasses used in these gauges most dependable providing a high strength resistant to both thermal and mechanical shocks and with the highest degree of visibility. These toughened and tempered glasses can withstand thermal shock and mechanical shock and vibrations and ensure long life of the level gauge. Mica is used in transparent level gauges to protect the glass and for higher temperature resistance of glass and the best quality ruby mica is only used by us. Gaskets are made from high quality Klingerite, PTFE, Graphite, Mettalic Graphite as per the demand of the service
