Non-contact measurement of the level of molten glass is demonstrated in an engineering scale induction-heated glass melter using microwaves. The microwave sensor is a corrugated horn used in mono static RADAR (RAdio Detection and Ranging) mode operating over 20 to 24 GHz with 20 dB gain. The ability to measure the level of the glass melt is demonstrated using an off-centered port in an induction glass melting furnace. © 2019 URSI. All rights reserved.

Feasibility of In-Situ Process Monitoring of Glass Melt in Industrial Furnace using Microwaves

2019 URSI Asia-Pacific Radio Science Conference, AP-RASC 2019

A specially designed air-cooled compact antenna is proposed for non-contact real-time radio detection and ranging (RADAR)-level measurement in furnace. 3-D modeling is used to optimize the surface profile of the RADAR antenna for beam symmetry and low sidelobe level over 20-24 GHz. The fabricated RADAR sensor deployed in mono-static mode has 0.19-mm measurement error for a static target. Measurements in a closed furnace at 1100 °C demonstrate the feasibility of non-contact in-situ monitoring of the level of molten metal for long duration (11 hours) without degradation in the sensor performance. © 2001-2012 IEEE.
