Quartz tube level gauge structure, principle, performance characteristics, main uses 1. General-purpose double-color quartz tube liquid level meter without blind area mainly consists of explosion-proof angle valve with flange, flexible tube, meter body, special-shaped quartz tube, color filter plate, drain valve, etc. It is characterized by wide application, elegant appearance, easy installation and durability. 1. The explosion-proof angle valve is equipped with safety steel balls that can automatically block the channel when the quartz tube accidentally breaks. 2. The flexible tube prevents surface deformation caused by installation and/or high temperature. 3. The center distance and observation direction can be adjusted, and there is no blind spot at the lower end. 4. The gas and liquid phases have obvious differences and strong contrast. It is suitable for a variety of working conditions, and can be used for carbon steel or 304, 1C18Ni9Ti, and 316L corrosion-permiss…
