摘要： The prior art describes the application of mechanical oscillators for the measurement of corrosion and/or deposition. Mechanical oscillators employ the use of resonance parameters, frequency and the quality factor Q, for the measurement of corrosion or deposition. However, the prior art does not consider the required precision for measuring frequency or Q in the presence of noise to make these measurements. In particular, the ability of the mechanical oscillator to measure small amounts of metal loss or deposition is not only dependent upon the mechanical design but is limited by the precision in determining the resonance frequency and Q. The present invention discloses methods for measuring these resonance parameters with a high precision in the presence of noise. This degree of precision is required to maximize the utility of these devices as sensitive probes for corrosion and deposition (fouling) measurement. All of the embodiments described herein employ curve fitting consistent with modeling the mechanical oscillator as a simple harmonic oscillator. This curve fitting procedure, combined with averaging and utilizing signal processing parameters to mitigate noise effects, adds considerable precision in measuring resonance parameters.
摘要翻译：现有技术描述了用于测量腐蚀和/或沉积的机械振荡器的应用。机械振荡器采用谐振参数，频率和品质因数Q来测量腐蚀或沉积。然而，现有技术没有考虑在噪声存在的情况下测量频率或Q所需的精度以进行这些测量。具体而言，机械振荡器测量少量金属损失或沉积的能力不仅取决于机械设计，而且还受限于确定谐振频率和Q的精度。本发明公开了用于测量这些谐振参数的方法在存在噪音的情况下具有高精度。这种精度要求是为了最大限度地利用这些装置作为用于腐蚀和沉积（结垢）测量的敏感探针。在此描述的所有实施例都采用与将机械振荡器建模为简谐振荡器一致的曲线拟合。该曲线拟合程序结合平均和利用信号处理参数来减轻噪声影响，在测量谐振参数时增加了相当的精度。

摘要： In various aspects, methods and systems are provided for monitoring catalyst bed levels using multiple sensors that are temporarily installed in a reactor during catalyst loading. The multiple sensors are able to take distance measurements at substantially the same time and at predetermined time intervals so as to provide a catalyst time profile. The catalyst time profile allows an operator monitor catalyst levels during and after catalyst loading. Once catalyst loading is completed, the multiple sensors are removed from the reactor.
