Model NIVUS NFP -Flow Measurement for Full Pipe
The NFP (NIVUS Full Pipe) has been developed particularly for flow measurement in full pipes with diameters between 100 and 800 mm. Based on the cross correlation method, the system can be used in a range of slightly to heavily polluted media. The NFP combines network measurements including adapted area weighting with a flow profile correction.
The NFP is outstandingly suitable for use in:
- Pump stations for rain water, dirty water and combined waste water
- Waste water treatment plants
- Pressure pipelines
- Drainage lines
- Return sludge lines
- Recirculation lines
