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,
