Osmosis filter

Differential pressure measurement in an osmosis filter

Process data

Measuring task:

Differential pressure measurement

Measuring point:

Filter

Measuring range up to:

+20 bar

Medium:

Sea water

Process temperature:

0 ... +25°C

Process pressure:

0 ... +20 bar

Special challenges:

Resistant to sea water

Application

Sea water is pressed through a semi-permeable membrane under high pressure. The semi-permeable membrane allows only water molecules to seep through. Salts, bacteria and viruses are retained in the filter. The finished product is almost the same as distilled water. A differential pressure measurement is needed to monitor the level of contamination across the filter.

Your benefit

Reliable

Approved materials according to FDA and EC 1935/2004, as well as local certification

Cost effective

Efficient cleaning of the filter is possible even during continuous operation

User friendly

Maintenance-friendly thanks to front-flush mounting
