Accelerometers (aka G-Meters) are used extensively in a wide range of applications including Aviation, Marine, Automotive, Military, and others. They are also used  in inertial navigation and guidance systems in airplane and ship autopilots.They help in a better understanding of static, such as gravity, or dynamic forces due to motion or vibration acting on an object.

Original Mechanical and more recent Digital accelerometers, used on civil and military aircraft, measure the instantaneous acceleration (or G-force) of an aircraft and its occupants compared to Earth's standard gravitational pull, in units of "G" (e.g., 1G, 2G). They enable pilots to monitor flight conditions, maintain safety, or practice aerobatics or combat maneuvers. Made by different manufacturers, they are offered as non-certified instruments, for use on  experimental and homebuilt aircraft, or certified products, installed on civil transport an military aircraft.

Mechanical accelerometers, included in this listing, use traditional components like proof masses, springs, and damping to measure acceleration based on displacement, offering high accuracy and durability for specific applications like flight stabilization and weapons communication. They are often of larger size and more expensive. Digital accelerometers, separately listed, are often Micromachined Micro-electromechanical (MEMS) systems, integrating sensors with microelectronic circuits for smaller size, lower cost, and high precision, making them ideal for flight stabilization, AHARS, and autopilot systems.

The choice of an accelerometer depends on the application's need for accuracy, size, cost, and resistance to harsh environments. 

Please consult the Product Description section and the supplied documentation for more information on different brands of our offered accelerometers.

Series 200 Turbine Flow Transducers by FLOSCAN INSTRUMENT CO. INC. measure flows of hydrocarbon fuels such as gasoline, kerosene, and #2 diesel fuel and other light transmitting, non-corrosive liquids of similar viscosity.  Typical fuel flow applications include aircraft fuel monitoring systems; gasoline, diesel, and gas turbine engine test stands; and industrial furnaces. The transducers give repeatable signals on gasoline across a 100 to 1 flow range down to 0.3 GPH.  The higher viscosity of diesel fuel reduces signal repeatability at flow rates below 2 GPH.  Pressure drops are very low compared to other turbine flow transducers.  The transducer bearing system is rated for continuous operation at the upper end of the flow range. The transducers produce a current pulse signal from an opto-electronic pickup with a preamplifier. 

Because of their superior accuracy and extraordinary repeatability, FLOSCAN transducers have quickly become the dominate fuel flow measuring sensors for general aviation but are also used in marine and other applications.

FLOSCAN aviation products are NOT TSO, PMA or STC'd.

Please refer to the specification table for additional information.
