Glass level measurement

Product catalog summary

Introduction
Glass is a versatile material used in various applications such as construction, laboratory equipment, and household products. The production of glass involves melting raw ingredients in industrial furnaces at temperatures over 1200°C. Effective level control after the melt furnace outlet is crucial for efficient and high-quality glass production.

Challenges in Glass Level Measurement
Traditional optical measurement methods, like lasers, require frequent maintenance and pose safety risks due to exposure to furnace heat and gases. These methods are unreliable without constant upkeep and necessitate the complete removal of refractory materials, increasing workplace safety hazards.

Radiometric Level Measurement
Radiometric measurements using gamma radiation provide reliable and safe solutions for glass level measurement. This method does not require complete refractory removal and is resistant to dust and gas, ensuring long-term stability and minimal maintenance. The system uses gamma radiation across the feeder channel to detect changes in molten glass levels, offering high accuracy and repeatability.

Advantages and Features

Online level measurement with good repeatability.
Resistant to dust and gas, with minimal refractory removal needed.
Environmentally safe, not exposing workers to furnace heat and gases.
Long-term stability matching the furnace's lifetime.
Non-contacting measurement with simple calibration adjustments.
Typical measuring ranges from 0 to 50 mm with an accuracy of +/- 0.5%.
Achievable resolution of 0.05 mm.

GLASS LEVEL MEASUREMENT Improving level control for efficient and high-quality glass production

Open the catalog to page 1

MEASURING THE GLASS LEVEL TO IMPROVE YOUR PRODUCTION Glass in various shapes and compositions encounters us in our daily lives as building material, laboratory equipment, optical instruments and household products. Industrial glass melt furnaces are used in glass production to melt raw ingredients (batch) into a molten glass at temperatures exceeding 1200°C. Level control just after the outlet of the melt furnace is one of the main process control challenges to facilitate efficient and high-quality glass production. Due to the harsh conditions, non-contacting measurement methods are mandatory....
