Accurately Measure Aircraft Fuel Flow with Liquid Turbine Flow Meters

Project Overview

　　In modern civil aviation flights, fuel consumption is an important part of an airline's operating costs. Therefore, there is an increasing demand for accurate measurement of aircraft fuel flow. Liquid turbine flowmeter is a widely used technology to measure high precision liquid flow, it is also widely used in civil and military aviation.

　　Liquid turbine flowmeter is a kind of instrument that uses the principle of fluid rotation mechanics to measure the flow rate. It is based on the effect of vortex mechanics produced by a fluid as it rotates, and uses an impeller to rotate in the fluid, thereby converting the fluid's flow rate into a rotational velocity. A sensor measures the rotational velocity and converts it to the flow rate of the fluid, thus accurately measuring the flow rate of the fuel.

　　A liquid turbine flow meter has many advantages over other flow meters. Firstly, it has a very high accuracy of less than 0.5%, so it can meet the demand for high precision fuel measurement. Secondly, the liquid turbine flowmeter has a very fast response time and can react to changes in flow rate in a short period of time. This is very important for the control and optimisation of fuel consumption in flight. In addition, liquid turbine flowmeters are also very stable and reliable because they have no dynamic zero drift and are not prone to failure during long-term use.

　　Of course, liquid turbine flowmeters have some limitations and shortcomings. Firstly, it is very sensitive to the state of the fluid, so the fluid needs to be pre-treated to ensure the accuracy and stability of the measurement. Secondly, the measurement accuracy of liquid turbine flowmeter will be reduced for fluids with relatively high viscosity. In addition, in extreme environments such as high pressure and high temperature, the liquid turbine flowmeter will fail to a certain extent.

　　Overall, the liquid turbine flowmeter is a very suitable technology for measuring aircraft fuel flow. Its high accuracy, fast response and stability and reliability provide strong support for in-flight fuel consumption control. At the same time, its limitations and shortcomings need to be noted to ensure its proper use and maintenance.
