Double Window Sight Glass is a simple assembly of two glasses on single cast or fabricated body at two opposite sides. Use of these types of flow indicator is for spot inspection and view of process parameter. It is available with various thickness and diameter of glass to suit various applications respects to fluid pressure and temperature.
Wide range of Toughen Glasses available to suit industrial pressure. All toughen glasses standard as per DIN 7080. Double Window Sight Glasses body end connection also can be Threaded End (BSP/NPT) or Welded End. Double Window Flow Indicator body length provide as per DIN EN 558-1 Standard.
In Double Window Sight Flow Indicator it is very easy to replace glass without dismantling the whole Sight Glass assembly from process line. Double window Sight Flow Indicator Glass gives better performance in application of Higher Pressure & Temperature.
