A water in fuel sensor, or WiF sensor, is an electronic sensor used to indicate the presence of water in fuel.It is installed in a fuel filter.When the water level in the water separator reaches the warning level, the WiF sends an electrical signal to the ECU or to dashboard (lamp). [1]
If the car's own vapor recovery system is working properly, then the Stage II nozzle will only be vacuuming normal fresh air and depositing that into the gas station's underground fuel storage tanks. That ends up causing evaporation of fuel vapors into the atmosphere, because too much pressure builds up in those fuel storage tanks.
Hall sensors are used in some automotive fuel-level indicators by detecting the position of a floating element in the fuel tank. [21] Hall sensors affixed to mechanical gauges that have magnetized indicator needles can translate the physical position or orientation of the mechanical indicator needle into an electrical signal that can be used by ...
However, the sensors are subject to corrosive elements or chemical contamination and may last only 1–2 years before a replacement is required. [5] Electrochemical gas detectors are used in a wide variety of environments such as refineries, gas turbines, chemical plants, underground gas storage facilities, and more.
The K9 Thunder is a South Korean 155 mm self-propelled howitzer designed and developed by the Agency for Defense Development and private corporations including Dongmyeong Heavy Industries, Kia Heavy Industry, Poongsan Corporation, and Samsung Aerospace Industries for the Republic of Korea Armed Forces, and is now manufactured by Hanwha Aerospace.

A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.
If the trigger on the main gun is pulled at the same time the tank encounters an irregularity in the terrain, oscillation of the gun barrel will cause temporary misalignment between a mirror-type laser reflector at the top of the barrel and a laser emitter (vertical sensor unit) at the base.
In its early history the company manufactured a variety of products including cameras and lead frames, but its business came to focus increasingly on aerospace manufacturing, and so it changed its name to Samsung Aerospace Industries in February 1987.
