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 unit has high accuracy and an unrivalled cost/performance ratio. Appropriate NIVUS accessories facilitate installation and keep maintenance expenses low. Therefore the NFP is an ideal substitute for obsolete or defect MIDs and other measurements. It is not necessarily required to remove existing measurement systems. 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 and many more
