1.2 Fields of application
The CarboVis 70x IQ is an online sensor for the on-site determination
of carbon sum parameters (and total suspended solids - TSS) in waste
water treatment plants.
The CarboVis 70x IQ
is an online sensor for the on-site determination
of nitrite, nitrate and carbon sum parameters in waste water treatment
plants.
The range of application comprises control, feedback control and mon-
itoring.
Measuring location
Ultrasound cleaning
system
The ultrasound cleaning system ensures low maintenance and long-
term reliable measurement operation.
The ultrasound source integrated in the sensor excites the measure-
ment windows to produce vibrations in the ultrasound range. The
movement of the surface as a result of this prevents the growth of
pollution in almost all cases and, thus, ensures reliable measured
values during continuous operation.
Compressed air cleaning
(option)
The sensor is designed to be equipped with an additional compressed
air-driven cleaning system, which supports the ultrasound cleaning
system as necessary.
1.3 Measuring principle of the UV-VIS sensor
The UV-VIS sensor operates according to the measuring principle of
UV-VIS spectrometry.
Any substance contained in a measuring solution attenuates a light
beam that penetrates the measuring solution. The attenuation (absor-
bance) of the light beam is measured for different wavelengths. The
wavelength dependent distribution produces the absorbance spec-
trum.
The wavelength range where an absorbance occurs is characteristic of
the substance. The extent of the absorbance depends on the amount
of the substance.
