200x30mm borosilicate sight glass DIN 7080

Product Description

Reflex Liquid Level Gauges use the R-form sight glasses. One side surface of ReflexGlass to use flat glass has several grooves for reflecting prism. The principle of theReflex Glass is based on the difference in the refractive indices of liquid and gas or inparticular of water and steam. Liquid level shows conspicuously dark hard color froliquid space and light white color for empty space. These Reflex series are not usedwith a mica shield. Therefore, this kind of level gauge is not recommended for usewith caustic, hydrofluoric, distilled water or other liquid corrosive to glass.

The Reflex Gauge is assembled firmly with gasket, reflex glass, cushion gasket andgauge cover on the body by U-bolts for SRG-1 & 2 and stud bolts for SRG-3 & 4.
