How a Float-Type Water Level Gauge Works - Technical Diagram & Explanation #117358 (License: Personal Use)

This diagram depicts a float-type liquid level indicator, where a buoyant float rises and falls with the fluid surface inside a vertical chamber. The float is connected via a rod or cable to a pointer that moves along a calibrated scale, allowing precise visual monitoring of tank contents. Inlet (G) and outlet ports enable circulation, while the transparent sight tube allows direct observation alongside the mechanical readout.
