Part No. NP8-5

Continuous measurement of particle concentration (TSS equivalent) with new ultrasonic measurement method using multi-frequency echo

Particle Concentration Measurement

measure. continuously. easily. maintenance-free.

The determination of solids concentrations with the parameter TSS (total suspended solids) is becoming more and more important. With NivuParQ 850 you can easily carry out permanent particle concen­tration (TSS equivalent) measurements in rainwater, combined water and flowing water. The low-maintenance system is used in part filled and full channels, ducts and pipes with of various shapes and dimensions. The measurement technology is based on ultrasonic backscattering and uses complex algorithms to record both the particle concentration (TSS equivalent) and the particle size distribution (incl. fine fraction smaller than 63 µm) in the water. In combination with a flow measurement, the summed load can be determined.


Benefits and Properties

  • Continuous measurement of particle concentration (TSS equivalent) with new ultrasonic measurement method using multi-frequency echo
  • Determination of 5 classes of particle sizes including the fine fraction < 63 µm
  • Very low operating costs, as no time-consuming sampling with laboratory analysis is required
  • Easy installation as well as quick and easy operation
  • Low-maintenance and reliable measurement system
  • Low investment costs for the measurement place setup
  • Approval of the measurement system for use in potentially explosive environments
  • Additional measurement parameters through integrated temperature and level measurement


Possible Applications

One possible application is the measurement of the precipitation-related dirt load in stormwater discharge. You can also use NivuParQ 850 to analyse the actual retention effect of stormwater treatment plants in drainage systems. The measurement data serve as a basis for optimal dimensioning of treatment structures. Another possible application is real-time control based on particle concentration in sewer networks with separation systems.
