Transparent Level Indicator

INTRODUCTION
The Mayur Instruments Transparent Level Indicators are designed for safe and positive visual indication of liquid level in vessels under high pressure and temparature conditions.

PRINCIPLE
The Mayur Instruments Transparent flat glass Level Indicators is a clear glass for visual indication and specially for interface services or where the liquid is dirty or viscous. Light striking on glass portion covered by liquid is reflected (absorbed) making this portion appear BLACK, whereas glass portion covering vapour space reflects light making it appear SILVERY - WHITE. Thus a sharp clear line marks the liquid, eliminating all possibilities of errors in reading.

INFORMATION
Transparent level gauges consist of two transparent glasses which are integrated with the liquid cavities on both sides. The level of the liquid via these devices is detected depending upon the dissimilarity in the transparent characteristics of the two glasses. Transparent level gauges are designed especially for the safe & positive visual indication of liquids in vessels & meet the most requirement of petrochemical fertilizer, chemical industries which involve high pressure, high temperature, liquids etc.
