    • A resonantly drivable straight tube type Coriolis flowmeter which is capable of correcting instrumental errors caused by a change in density and temperature of measurable fluid. A coaxial double tube body that is composed of an inner tube wherein fluid to be measured flows and an outer tube with a balance weight attached thereto for equalizing natural frequencies of the inner and outer tubes is driven at a resonant frequency having a constant amplitude. A change of fluid density causes a change of amplitude ratio of the inner tube and the outer tube, resulting in shifting of an instrumental error. At this time, a resonant frequency detecting circuit detects a resonant frequency without detecting the amplitude ratio. An instrumental error detecting circuit stores a relation between resonant frequencies and fluid densities and a relation between fluid densities and instrument errors and conducts correction of an instrumental error according to the detected resonant frequency. An instrumental error caused by thermal deformation of the inner tube and the outer tube which are different from each other in material and shape can be also corrected by using similar correcting means.
    • 可共振驱动的直管式科里奥利流量计,其能够校正由可测量流体的密度和温度变化引起的仪器误差。 一个同轴双管体,由其中待测量的流体流过的内管和连接有平衡重的外管组成,用于使内管和外管的固有频率均衡,以恒定振幅的共振频率被驱动。 流体密度的变化导致内管和外管的振幅比的变化,导致仪器误差的偏移。 此时,谐振频率检测电路在不检测振幅比的情况下检测谐振频率。 仪器误差检测电路存储共振频率和流体密度之间的关系以及流体密度与仪器误差之间的关系,并根据检测到的共振频率进行仪器误差的校正。 也可以通过使用类似的校正装置来校正由内管和外管在材料和形状上彼此不同的热变形引起的仪器误差。

    • A double-tube type Coriolis flow meter is provided for measuring mass flow. The flow meter includes a straight flow tube (4) through which the fluid being measured flows, a hollow outer tube (5) secured at both ends thereof to act as a counterbalance, a drive unit (7), and a pair of sensors. The flow tube (4) is caused to vibrate by the drive unit (7) so that the mass flow of the fluid is measured by detecting a phase difference proportional to Coriolis force acting on the flow tube (4) by the sensors. Sheet members (coupling plates 6) secure the flow tube (4) to both ends of the outer tube (5) and integrally form the coupling plate (6) with tube-assembly supporting leaf springs (14) in the double-tube type Coriolis flow meter. By connecting the flow tube to the outer tube via the sheet members in this manner, stresses produced between the tubes are absorbed and a uniform temperature distribution is maintained in the outer tube and manufacturing costs are reduced.

    • An imaging unit takes an image and converts the image into a video signal. A display unit displays the image carried the by the video signal. An average luminance calculating unit calculates average luminance of the image per first predetermined period. A detecting unit calculates a ratio of maximum to minimum average luminance of the average luminance over a second predetermined period that is an integer multiple of the first predetermined period and determines whether the ratio is equal to or higher than a predetermined value. The detecting unit determines that the image taken by the imaging unit is an image of a movie projected onto a screen when it is determined that the ratio is equal to or higher than the predetermined value. A warning unit sends a warning signal to the display unit when the detecting unit determines that the image taken by the imaging unit is the image of the movie. The display unit then displays an warning message carried by the warning signal with the image.
