Reflex Level Gauge
Reflex Liquid Level Gauges provide direct observation of tank or vessel liquid levels using grooved R-form sight glasses and differences in the refractive indices of liquid and gas. The page describes applications involving high temperature, high pressure, boiling, viscous and foamy liquids.
Design features
- Reflex Liquid Level Gauges use the R-form sight glasses.
- These Reflex series are not used with a mica shield.
- The Reflex Gauge is assembled firmly with gasket, reflex glass, cushion gasket and gauge cover on the body by U-bolts.
- The manual adjustment of isolation valve at the input of the media entering the chamber reduces the bubbling.
- The gauge has a relatively spacious internal area where foamy liquid is held from forming foams.
- Sealing gaskets and cushions for tight sealing at rated pressure and temperature.
