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 vacuum-
resistant.
● 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,

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. non-
contact 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.
