NivuParQ 850
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 increasingly important due to legal requirements (e.g. European Water Framework Directive, DWA A-102). In order to ensure good water quality, the requirements for rainwater treatment plants and discharges into water bodies are becoming ever more stringent.
The NivuParQ 850 measurement system makes it easy to take continuous particle concentration measurements in rainwater, surface water or hydroelectric applications. The low-maintenance system can be used in part filled and full channels, canals and pipes of various geometries and dimensions. The measurement technology used is based on ultrasonic backscattering/attenuation and uses complex algorithms to determine both the particle concentration and the particle size distribution in the water. In combination with a flow measurement, the total dirt load can be determined.
Your Benefits
- Continuous and drift-free measurement of particle concentration (TSS equivalent) using new ultrasonic measurement method with multi-frequency echo
- Measurement in the flow cross-section
- Determination of five particle size classes
- Very low operating costs, as no time-consuming sampling with laboratory analysis is required
- Easy installation and quick and easy operation
- Low-maintenance and reliable measurement system
- Low investment costs for measurement place setup
- Additional measurement parameters through integrated temperature and level measurement
- IoT-ready with global 4G connectivity for maximum availability and digital services
Possible Applications
- Determining the effectiveness of rainwater treatment plants
- Measuring precipitation-related dirt load in rainwater discharge
- Verification of retention filters and solids filters
- Measuring at the intake of hydroelectric power plants
- Checking dirt loads from direct dischargers into water bodies
- Quality-dependent control of rainwater and wastewater
- Measurement of suspended solids transport in surface waters
