Description

Reflex level gauge is as known as reflex glass level gauge and prismatic level gauge. Reflex level gauges are commonly used for level detection within a vessel, and the primary principle is based on the difference in refractive indices of vapor and liquid. Compared with transparent level gauge, reflex level gauge can display the liquid level more clearly without the aid of auxiliary light source.

Reflex level gauge’s core components are one or several reflex gauge glasses. One of its surfaces has grooves with section angle of 90 ° which is installed towards the chamber. The upper part of the chamber is filled with gas and the lower part is filled with liquid when the liquid level gauge is working, liquid level is clearly observed by different brightness of the glass in the liquid and in the gas/vapor zone.

To avoid leakage in case of glass breakage, safety ball-check device is usually provided in cross-fittings or shut-off valves.

Reflex glass level gauges can be used in most of the cases and offer great advantages in terms of: low initial cost, low operating cost, easy level reading, no need power supply.
