Sight Glass Type Level Gauge

Sight Glass Type Level Gauge is a mechanical liquid-level monitoring device consisting of a transparent glass or plastic tube (sight glass) installed vertically between two process connections on a tank or vessel, allowing operators to visually observe the liquid level inside by direct sight, with scale markings for precise measurement; it is widely used in industrial processes, chemical plants, and storage systems for real-time, reliable level indication in non-pressurized or low-pressure applications.
