3.3 Installation
3.3.1 General information
The measuring principle of the ViSolid
®
700 IQ (SW) (scattered light
measurement) places specific requirements on the measurement
location and on the installation of the sensor.
If there is a low level of total suspended solids (< 2000 mg/l SiO2 or
< 1000 mg/l TSS), infrared light penetrates deep into the sample. Thus,
the measuring environment can have a significant effect on the
measured value displayed. Light that is reflected or scattered by the
ground or wall can strike the detector in the sensor and, thus, simulate
an increased level of total suspended solids.
Scattered light can be kept away from the measurement windows to a
great extent by favorable positioning of the sensor. Therefore, an
optimum installation position is particularly important for the
measurement of lower values of total suspended solids.
Note
Always maintain a distance of at least 10 cm from the ground and wall.
The following factors affect the measurement of the TSS contents:
 Inclination of the sensor (see section 3.3.3)
 MIQ/MC 2
