Reflex Level Gauge

Product Details

Level gauges are sensing and measuring instruments that are used to detect the level of a fluid or gas in a tank or similar storage container. These devices are widely used in industrial process applications and are employed to measure the fluid levels in drums, tanks, pressure vessels, or other similar applications.

Level gauges are often employed in cases where performing a direct physical measurement of the level of the 􀃃uid is either not possible or practical, such as when the fluid being measured is hazardous or when the tank or vessel containing the fluid is sealed and under pressure.

Reflex Level Gauge: Reflex glass level gauges working principle is based on the light refraction and reflection laws. It uses glasses with the face fitted towards the chamber shaped in order to have prismatic grooves with section angle of 90°.

When in operation, the chamber is filled with liquid in the lower zone and gases or vapours in the upper zone; the liquid level is distinguished by different brightness of the glass in the liquid and in the gas/vapor zone. The re􀃃ex level gauges do not need a specific illumination: the day environmental light is enough. Only during the night an arti􀃂cial light must be provided.

Transparent Level Gauge: Transparent Level Gauges employ two Transparent Glasses 􀃂tted with a liquid chamber on either side. The liquid level is indicated as a result of difference in the transparent properties of the two media. For water / steam applications, an illuminator is mounted on the rear side of the gauge with its light rays de􀃃ected upward into the water column. This enables the observer to see illuminated surface of the water as the light rays impinged on the surface of separation between water and steam are reflected back to the eye of the observer.Level gauges are sensing and measuring instruments that are used to detect the level of a fluid or gas in a tank or similar storage container.
