Reflex Glass Level Gauges

A reflex glass level gauge shows the liquid behind a glass whose inner face has prismatic grooves. Light is absorbed where there is liquid, which looks dark, and reflected where there is steam or gas, which looks bright, so the level line is clearly distinguished.
The store range offers PN16 reflex gauges from 310 mm to 2115 mm long and gauges with glass sizes IV to IX. Spare reflex glasses, gaskets and sealing rings are also supplied separately.
Main Applications
- Steam boilers
- High-temperature and hot water boilers
- Feed water and condensate tanks
- Pressurised process vessels
- Oil and fuel service tanks

Which material? Reflex glass shows the interface between liquid and steam, so even colourless liquid levels read clearly. Remember that glass can be attacked by acidic or alkaline liquids and high-pH boiler water; include glass and gaskets in the maintenance plan.
