CCD-based virtual instrument for the peak of the waveform

, The system has easy to use, high degree of automation, availability and other characteristics. Through the above description,[link widoczny dla zalogowanych], you can see using LabVIEW software to develop test and measurement instruments with simple programming, development of upgrades more convenient, powerful features of mathematical analysis, testing and teaching in industrial experiments, have broad application prospects and learning research value.

, (9), (10), (11) have: (1l +12) toOsin (tot a West) △ f = Qm (zl +12) 3toOSsin (tot a coin) rational design and selection of pipe materials structure, parameters and in the weak damping case, the desirable coffee, zero, Therefore,[link widoczny dla zalogowanych], the sensitivity coefficients can be calculated:: At: (12) a 3 on the standard device in the flow tube Coriolis meters have been carried out experiments, the parameters for the elastic modulus E = 206GPa, Poisson's ratio / z = 0-3, vibrating tube density P = 8000kg / m. Vibration control parts of length (see Figure 1) are / = 30ram, Zl = 20ram, 12 = 400mm, 13 = 30mm, vibrating tube diameter D = 8mm, diameter d = 6mm. Experimental medium is water, room temperature experiments, the flow meter range (0-100) kg / h, was varied from experiment (0-0.26) ~ s, so you have a sensitivity of 9.236 ~ s / (kg / s), numerical solution of 9.431 ~ s / (kg / s), the error was 2.1%, which proves its correctness. 5 Conclusion This paper has established a new straight tube Coriolis mass flowmeter of the theoretical model, obtained sensitivity formula, has a guiding role. But there are some model assumptions, ignoring some of items, resulting in certain error, the latter shall gradually improved.
