An all-in-one (AIO) cooling unit, installed in a case DIY water cooling setup showing a 12 V pump, CPU waterblock and the typical application of a T-Line Schematic of a regular liquid cooling setup for PCs. Liquid cooling is a highly effective method of removing excess heat, with the most common heat transfer fluid in desktop PCs being ...
In 2002, the new generation of VapoChill was released. In 2003, Asetek branched out into liquid cooling with its WaterChill brand of liquid coolers. In 2005, they released the first 12-volt pump system. [2] In the early 2000s, Chip-Con/nVENTIV and its Prometeia line of coolers emerged as the primary competitor to the Asetek Vapochill line.
Liquid cooling is also used to remove heat from large buildings by using chillers which transfer the coolant from the evaporator to air handling units, chilled beams and fan coil units inside the building, and to the cooling towers from the condenser if the condenser is liquid-cooled.
According to British Standards, correctly calibrated, used and maintained liquid-in-glass thermometers can achieve a measurement uncertainty of ±0.01 °C in the range 0 to 100 °C, and a larger uncertainty outside this range: ±0.05 °C up to 200 or down to −40 °C, ±0.2 °C up to 450 or down to −80 °C.

Liquid crystals possess the mechanical properties of a liquid, but have the optical properties of a single crystal. Temperature changes can affect the colour of a liquid crystal, which makes them useful for temperature measurement. The resolution of liquid crystal sensors is in the 0.1 °C (0.2 °F) range.
1612 — Santorio Sanctorius makes the first thermometer for medical use. 1617 — Giuseppe Biancani published the first clear diagram of a thermoscope 1624 — The word thermometer (in its French form) first appeared in La Récréation Mathématique by Jean Leurechon, who describes one with a scale of 8 degrees.
In a magnetic indicator is a float on the surface of the liquid contains a permanent magnet. The liquid is contained in a chamber of strong, non-magnetic material, avoiding the use of glass. The level indicator consists of a number of pivoting magnetic vanes arranged one above the other and placed close to the chamber containing the float.
