CAPAFLUX
Highlights
Capacitive electrodes for
non-contact measurement
Hazardous-duty version,
flameproof enclosure
Self-supporting ceramics
measuring tube,
press-fitted into stainless
steel housing
Meter sizes DN 25 -100 or 1”- 4”
Measuring error
≤ 0.5% of the measured value,
‘sandwich’ design, easy installation,
reliable and safe operation
Electrical conductivity
≥ 0.05µS/cm,
e.g. ultrahigh-purity water, alcohols,
glycerols, glycols, etc.
Dimensionally stable measuring tube,
very good thermal and long-time stability,
no flow, creep and no abrasion,
as is usually the case with plastic liners
No crevices, no blind spots in the
measuring tube, conforms to food
standards, extremely smooth,
surface roughness < 0.8 µm
Design
