Sight glasses, also known as sight windows or sight indicators, are transparent or translucent devices used to visually monitor media levels, flow, and clarity in a wide range of industrial processes and equipment. Sight glasses may be installed in tanks, pipelines, or equipment such as pumps, compressors, or reactors, to provide operators with a visual indication of the fluid level, flow rate, or the presence of impurities or bubbles.

Sight glasses are typically made of glass, plastic, or metal, depending on the specific application and requirements. They may be circular, rectangular, or cylindrical in shape, and come in various sizes and configurations to fit different types of equipment. Sight glasses may include features such as gaskets, seals, or wipers to ensure a tight and secure fit and to protect the glass from damage or contamination. In addition, some sight glasses may be equipped with lighting or heating elements to enhance visibility or prevent condensation or frost from forming on the glass.
