摘要： An arrangement for determining concentration of at least two sample components in solution of at least three components comprises a refractometer as a first instrument for measuring refractive index data as a first quantity of the first sample component. In addition the arrangement comprises a second physical quantity measuring device for measuring second physical quantity as a second quantity data of the second sample component, such as a device for measuring conductivity. The second physical quantity is advantageously essentially independent on said refractive index, but is more strongly dependent on at least concentration of at least one second sample component of said solution. Further the arrangement comprises a data processing unit for determining said concentration of at least two sample components by using said refractive index data and second quantity data in an additive way after a variable substitution performed by said data processing unit on the refractive index data.

摘要： An exemplary arrangement includes a prism-shaped measuring window, which has a measuring surface adapted to contact a substance being measured. A first surface is adapted to direct light originating from a light source to the measuring surface through the measuring window. A second surface is adapted to direct totally reflected light from an interface between the measuring surface in contact with the substance being measured and a substance being measured outside of the measuring window. A first lens arrangement is adapted to focus the light from the light source on the first surface. A second lens arrangement is adapted to focus the totally reflected light passing through the second surface to a device used for analysis. A lens in each of the first and second lens arrangements closest to the measuring window is integrated into the measuring window and establishes optical refractive power in the first and second surfaces.

摘要： Method and device for measuring the Abbe number in a process liquid. Light generates successively at wavelengths of 486.1 nm, 589.3 nm and 656.3 nm and different light wavelengths are directed successively through a measuring window in the process liquid so total reflection occurs at each wavelength on the measuring window surface and process liquid. Partial light reflected at each wavelength is directed to a sensor, whereby an image forms on the sensor surface; between light and dark boundary region corresponding to each wavelength critical angle, in which total reflection occurs. At each wavelength between light and dark boundary region detection by image analysis. At each wavelength, dependency between light and dark boundary region and refractive-index of process liquid measurement is detected, the Abbe number by refractive-index values obtained from: V D = n D - 1 n F - n C ; nD=refractive-index of process liquid to measure at 589.3 nm; nF=refractive-index at 486.1 nm; and nC=refractive-index at 656.3 nm.

摘要： A method and arrangement are disclosed for measuring a flow rate of optically non-homogeneous material in a process pipe. The non-homogeneous material can be illuminated through a window. Images are taken with a camera, through a window, of illuminated non-homogeneous material. Correlation between temporally successive images determines travel performed by the non-homogeneous material in the process pipe between capture of temporally successive images. Velocity of the non-homogeneous material is determined by the time difference between the successive images and the travel.
