No restrictions ...
... through insulating products with a film-forming tendency:
asphalt, latex suspensions
... through low electrical conductivity: ultrahigh-purity water, alcohols, glycerins, glycols
... through high solids contens: fruit pieces, pulps, concrete
... for sterile processes: chemical and food industries
... when used in hazardous areas:
ATEX approval
FM certification pending
... through electrode materials:
the capacitive electrodes are located behind the ceramic tube, i.e. noncontact measurement, no contact with the process product.
Calibrated on EN 17 025 accredited calibration rigs, accuracy of calibration better
than 99.97% of the measured value.

Special advantages
●capacitive electrodes for non-contact measurement.
●the measuring section is resistant to abrasion from even high solids contents.
●the ceramic measuring tube is dimensionally stable and vacuumresistant.
●the special shape of the measuring tube helps to optimize the flow profile, even with minimum pressure drop, refer to diagram on page 3.
●the measuring error is less than 0.5% of the measured value.
●the integral design ensures easy installation, safe and reliable operation.
●the crevice-free measuring tube has no blind spots and conforms to food requirements, the ceramic surface is ultrasmooth,
Ra < 0,8 µm surface finish.

Highlights
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.
Capacitive electrodes for non-contact measurement
No crevices, no blind spots in the measuring tube, conforms to food standards, extremely smooth, surface roughness < 0.8 µm
Hazardous-duty version, flameproof enclosure
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
Meter sizes DN 25 -100 or 1”- 4”
Self-supporting ceramics measuring tube, press-fitted into stainless steel housing
