700 IQ (SW)
Total suspended solids
measurement
The measurement of the total suspended solids in aqueous media with
the ViSolid
®
700 IQ (SW) is carried out as a scattered light
measurement. This records the suspended proportion of total
suspended solids (TSS).
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 front face
containing the measurement windows to oscillations in the ultrasound
range. The resulting movement of the surface prevents the growth of
pollution right from the start and, thus, ensures reliable measured
values during continuous operation.
AutoRange function Within the enormously large measuring range (0 - 40000 mg/l SiO2
and 0 - 40000 mg/l TSS depending on the measured material), the
AutoRange function selects the optimum resolution for the respective
measured value.
SensCheck function This monitoring function that is integrated in the sensor is used to
continually check the sensor function and to register any malfunctions
caused by the measuring medium. The correct operation of the
ultrasound cleaning system is also continuously monitored.
