Bypass liquid level indicator provides safe measurements
Mike EdwardsProducts glass tube Kobold video
The SZM type glass tube level indicator from Kobold 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, the company says, 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. Installation length means the distance between the horizontal centre lines of the two flanges, that is minimum 370 mm, and maximum 3080 mm.
The glass tubes longer than 1500 mm are welded. The bottom, and top sealing of the glass tube is by two O-rings each, the material of which is to be chosen to be chemically compatible with the liquid measured. Standard sealing material is FPM, whereas EPDM or NBR are available on request.
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.
