New iterative deconvolution method for layered materials inspection has been suggested. Some of the more common flow meters in use include: https://www.aircraftsystemstech.com/2017/06/fuel-system-indicators.html. Comprehensive portfolio for gases, liquids and steam. It was shown that bias errors for cosine interpolation do not depend on signal center frequency.
Although viscous shear has not been ignored in these studies, a uniform velocity profile assumes that the sheared region is infinitely thin.
However, far away from the surface of the transducer, due to vortex motion in the cavity of the recess, the flow velocity is bigger in the downstream recess. - SS signals improve the energy penetration at frequencies beyond the passband of ultrasonic transducer. The main principle is to measure the flow of fuel before and after the engine and/or generators. ©2020 Sentronics Limited. This chart approximates the fuel consumption of a diesel generator.

Try finding the one that is right for you by choosing the price range, applications, or specifications that meet your needs.
10-4 m/s standard deviation and 0.5. New, reiterative, deconvolution technique has been suggested to reduce the aforementioned type of bias errors. 7. No flow coefficient drift, long-term stability. Random errors of the ToF have been obtained by taking large number of runs (more than 1000) and obtaining the standard deviation of the ToF value estimated. New equation for interpolation bias errors of time of flight estimation has been proposed. The response surface methodology (RSM), a widely-used optimization method in DOE, was, We present the design and experimental results of a near-field scanning microwave microscope working at a frequency of 1 GHz. P. 326 – 331.
