The digital fuel gauge in a 2018 Mazda 3 showing a nearly-empty tank along with a distance to empty display. Typical old-style fuel gauge on a 50 ccm chinese-made scooter from 2008, with the internationally used pictogram of a gas pump. The system can be fail-safe. If an electrical fault opens, the electrical circuit causes the indicator to ...
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
The aircraft involved in the accident, however, had faulty fuel gauge readings, causing the pilots to be unable to accurately know the amount of fuel that they had moved to the other tanks. Even though the crew conducted asymmetric fuel transfer, such practice was not considered abnormal as it was common for the operation of the Tupolev Tu-154.
By contrast, fuel exhaustion (also called fuel depletion) is an occurrence in which the vehicle in question becomes completely devoid of usable fuel, with results similar to those of fuel starvation. [2] All engine-powered modes of transport can be affected by fuel starvation, although the problem is most serious for aircraft in flight. Ships ...
A variation of magnetic sensing is the "Hall effect" sensor which utilizes the magnetic sensing of a mechanical gauge's indications. In a typical application, a magnetism-sensitive "Hall effect sensor" is affixed to a mechanical tank gauge that has a magnetized indicator needle, so as to detect the indicating position of the gauge's needle.
Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
A problem with the WDP-3A was that it would get uncomfortably hot inside the driving cabin on the radiator side and the locos were nicknamed “toasters” by the locomotive pilots. The WDP-3A was best known for hauling the Trivandrum Rajdhani and later on the Mumbai CSMT - Karmali Tejas Express through the Konkan Railway at a top speed of 120 ...
For example, a gauge with 3% manufacturer-stated accuracy can be changed to 4% so that a 1% accuracy standard can be used at 4:1. If the gauge is used in an application requiring 16% accuracy, having the gauge accuracy reduced to 4% will not affect the accuracy of the final measurements. This is called a limited calibration.
