How Cooling Towers Work (W/ Diagram, Pictures & Principles) …

The water is exposed to air as it flows throughout the cooling tower. The air is being pulled by an motor-driven electric "cooling tower fan". When the air and water come together, a small volume of water evaporates, creating an action of cooling. The colder water gets pumped back to the process/equipment that absorbs heat or the condenser.

Displacer (buoyancy) Level Transmitter Principle, Limitations, …

Measurement principle The principle of displacement level measurement is based on Archimedes Principle. Displacement instruments determine liquid level by sensing the buoyant force exerted on a displacer by the liquid it displaces. Unlike floats, in float‐type level instruments, the displacer moves very little relative to the rising or falling liquid.
