れる。 In the figure, 1 is a transparent measurement tank through which the fluid to be measured passes, and light from a light source 2 is converted into a wide parallel beam by two convex lenses 3 and 4 through a slit (not shown) and irradiated onto the measurement tank 1. , the tank 1
The transmitted light is received by two measurement side detection devices 5 and a reference side detection device 5'. The devices 5 and 5' are each equipped with pre-adjusted optical filters 6, 6' and photocells 7, 7'. The other filter 6' is one that matches the spectral range in which the change in transmittance is noticeable, but the other filter 6' is one that does not respond to changes in the measured component, that is, the change in transmittance is minimal with respect to changes in the concentration of the measured component. The ones that cover the spectral range are selected. The light transmitted through the filters 6, 6' is received by photocells 7, 7'. This generated signal is amplified by amplifiers 8 and 8', and the amplified signal is ratio-calculated by a ratio converter 9 and displayed on a display meter 10 and a recorder 11. are transmitted via the alarm and control output device 12 to automatic control equipment, such as equipment temperature, pressure, opening and closing of valves, etc.

できる。 In this way, the light that has passed through the two types of filters 6 and 6' interacts equally with each other according to the ratio method described above,
Variations caused by both are eliminated by the ratio synergistic process, so it works to minimize the effects of fluid temperature, bubbles, wind scattered light, etc. during measurement, and also minimizes the effects of changes in the light source, voltage fluctuations, etc. This allows for accurate measurement and output display at all times.

Analyzes of product color, specific gravity, etc. are conventionally carried out in the main line. P 1 position Q
Workers were opening the pot and taking samples. Position Q is close to the storage tank, so it has the disadvantage that it is too late to correct the operating conditions after a reject is discovered there.In addition, the heavy gas oil is separated by moisture and wax before entering the dehydration tower. Because there are many
When measured with a color meter in a test room after cooling, the properties of the heavy diesel oil differed from those actually flowing through the pipes, and it was therefore desirable to measure the color at a high temperature location (at high temperatures, water and (There is no interference with measurement due to wax content.)
