A data logger (also datalogger or data recorder) is an electronic device that records data over time or about location either with a built-in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer), and called digital data loggers (DDL).
Some data loggers are placed on the outside of the package or in the truck or intermodal container to monitor the air temperature. Placement of data loggers and sensors is critical: Studies have shown that temperatures inside a truck or intermodal container are strongly affected by proximity to exterior walls and roof and to locations on the ...
Fuel-management systems are used to maintain, control and monitor fuel consumption and stock in any type of industry that uses transport, including rail, road, water and air, as a means of business. Fuel-management systems are designed to effectively measure and manage the use of fuel within the transportation and construction industries.
Shock and vibration logger with integrated 3-axis digital accelerometer and lithium-polymer battery. A shock data logger or vibration data logger is a measurement instrument that is capable of autonomously recording shocks or vibrations over a defined period of time. Digital data is usually in the form of acceleration and time. The shock and ...
The air data boom is mounted on the vehicle in a location that allows for relatively undisturbed air to be measured. To attain such undisturbed air, mounting is usually done on the nose, wing, or upper horizontal stabilizer of the vehicle. Diagram of 100600-style air data boom.

Fuel-saving devices are sold on the aftermarket with claims they may improve the fuel economy, the exhaust emissions, or optimize ignition, air flow, or fuel flow of automobiles in some way. An early example of such a device sold with difficult-to-justify claims is the 200 mpg ‑US (1.2 L/100 km) carburetor designed by Canadian inventor ...
A single-engine piston aircraft has a simple fuel system; a tanker (such as the KC-135), in addition to managing its own fuel, can also provide fuel to other aircraft. [1] Fuel is piped through fuel lines to a fuel control valve (usually known as the fuel selector). This valve serves several functions.
For an aircraft engine, changes in airspeed or altitude cause changes in air speed and density through the engine, which would then have to be manually adjusted for by the pilot. A fuel control unit attempts to solve those problems by acting as an intermediary between the operator's controls and the fuel valve.
