Keywords MEMS, flow sensor, curve fitting, least square method [Pg.27]

This article mainly introduce based on micro electro mechanical system (MEMS) flow sensor FS4001-200—CV—CH4 desorption of gas in coal bed recorder in the research and design method. For trace, low pressure loss and the volume of a gas flow velocity measurement. [Pg.27]

The PC software design, using VC-H- to program development, completed the linear fitting based on nonlinear least squares curve fitting and design, thus made further precise calculation and post-processing on lower machine data. [Pg.27]
