Description
- Cost-efficient alternative to EMFs/mag meters considering the total costs
- Very high measurement accuracy
- Quick and easy retrofitting for all pipe materials
- Uncomplicated and reliable commissioning even under process conditions
- Flow metr for river water, rainwater, dirty water, sludge, cooling water, domestic and industrial wastewater and more.
- ATEX approval for Ex-Zone 1
- Easy assessment of measurement places
- Easy-to-read display
- For use with Type POA pipe sensors
NFP (NIVUS Full Pipe) flow meter was developed particularly for flow measurement in full pipes from DN 100 to DN 800. The system is based on the cross correlation principle for slight to heavily polluted media. The NFP combines grid measurements featuring adapted weighting of areas with velocity profile correction.
The unit stands out for highest measurement accuracy and a very good price-performance ratio. Appropriate NIVUS accessories facilitate installation and maintenance at low costs. The NFP therefore is ideal also to replace obsolete or defective EMFs and other measurement systems. Existing flow meters do not have to be dismantled.
Typical NFP applications
- Pump stations for rainwater, dirty water and combined water
- WWTPs
- Pressurised pipelines
- Drainage pipelines
- Return sludge pipelines
- Recirculation pipelines
- and many more
