  • Page 26: Measurement Principle

    2-11 <2.Specification> Measurement Principle The rotary cell length modulation method, which combines high performance and reliability, is adopted in this unit. Two cylinder cells are placed, arranged with the light source and detector in a position where they are decentered from the center of cylinder as shown in the figure below. By rotating these two cylinder cells with the centers of the light source and detector as the rotation center, the distance between the 2 cylinders (cell length) is modulated continuously and periodically.
  • Page 27 2-12 <2.Specification> TURB (turbidity) Measurement TURB measurement is performed by using the visible light (VIS) absorbance. The measurement method is the transmitting absorption method. Calibration with the standard solution enables a simple measurement of TURB. Measure in the measurement range of 200 deg. or below. If measuring in a measurement range that exceeds the specified value, the linearity deteriorates due to the scattering light influence.

    App.3-1 <App.3 Piping> App.3 Piping App.3.1 Piping procedure • When there may be pipe freezing, install a pipe warming device. • To prevent backpressure, make the exit-side pipes as short as possible. In addition, the pipe exit must allow the air to flow out freely, and must not be submerged in water. Do not install the pipe vertically.
  • Page 125 CAUTION • The diameters of the pipes shown in Table 3 match the diameters of connectors for UV700G. If the water sampling point is distant from the device, use pipes with larger diameters than those mentioned in Table 3. • When piping the drain pipe, overflow pipes (1) and (2), and the discharge pipe, slope them sufficiently so that the ends of the pipes can not be submerged in water.
