reflect glass level gauge SS304 316

     Reflex glass level gauges working principle is based on the light refraction and reflection laws.
     Reflex glass level gauges use glasses having the face fitted towards the chamber shaped 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 vapors 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 reflex level gauges do not need a specific illumination: the day environmental light is enough. Only during the night an artificial light must be provided.

Applications
     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.

Features:
     1. They do not need electrical power to operate. This can be a great advantage in the case of a power outage.
     2. Simple to install – no calibration is necessary.
     3. Can be used as a reference to check, or calibrate, other level technologies.
     4. Pressure rating from vacuum to 4Mpa.
     5. Temperature rating from -20℃ to 450℃
     6. Not affected by the chemical or electrical properties of the process liquid.
     7. Specific gravity, dielectric, conductivity, surface turbulence, vapor, foam, etc. no longer needs to be considered.

The classification and scope of use of Reflex glass level gauges are as follows:
     1. Heat-tracing glass plate level gauge: mainly used for the occasions where the measured medium needs heat preservation;
     2. Frost-proof glass plate level gauge: mainly used for occasions where the operating temperature of the medium under test is -196~0℃ and the glass is prone to frosting;
     3.Glass plate level gauge without blind area: mainly used in situations where continuous observation is required and blind areas are not allowed in the visual range;
     4. Two-color glass plate level gauge: mainly used for occasions where the medium is colorless and transparent liquid and liquid level is not easily observed;
     5.Uv - proof glass plate level gauge:mainly used for the occasions where the measured medium is afraid of ultraviolet light;
     6. Wide liquid chamber glass plate level gauge: mainly used for occasions where the viscosity of the measured medium is relatively large or the volume of the instrument is relatively large;
     7. Illuminating glass plate level gauge: mainly used for night observation.
