L.B. BOHLE MASCHINEN + VERFAHREN GMBH

Quelle:Absolute care is essential in pharmaceutical production – after all,people’s lives and health depend on the correct agent composition
and the avoidance of contamination. With the aid of the FLOWave Type8098 flowmeter, the universal pharmaceutical cleaning system PURof L.B. Bohle Maschinen + Verfahren GmbH can quickly and simply
satisfy these high hygiene standards.

Did you know?
Surface acoustic waves (SAW) occur in nature, for example
during seismic activity. We have harnessed these effects
in a patented technology for the inline flow measure­mentof fluids. This means that FLOWave* dispenses entirely
with sensor elements in the measuring tube that come into
contact with the substance to be measured.
