SZM Bypass level indicator - Kobold

As an indicator of levels in small and medium-sized, upright or horizontal, round vessels, the SZM is particularly recommended for use in the food industry, water treatment and the pharmaceutical and chemical industries.
The SZM type glass tube level indicator is applicable for the indication of liquid level in small and middle-sized, standing or lying round containers used in food, pharmaceutical and chemical industries. The loads occurring at the installation are absorbed by the outer armature, thus the glass tube is protected against breaking.

The outer armature also protects the glass tube against the mechanical impacts that may occur following the installation. It is recommended that the normal design level indicators be fitted on vessels containing pure liquids, while the  indicators mounted with cleaning stubs (a bottom, or bottom-top stub) be fitted on containers filled with contaminated liquid.

The level indicator may be furnished with capacitive level sensors - max. 3 pieces over 100 mm - as requested (NAMUR design), which monitor the minimum and/or maximum level or any level along the scale.
Anodised aluminium rule with indication of level or volume may be mounted optionally on side of the outer armature. The scale can be engraved on the aluminium rule or the glass tube, or can be printed on a foil and to be attached to the glass tube or aluminium rule.
