MODEL KWR AND KWT WELD PAD STYLE FLAT GLASS GAUGES

INSTALLATION / OPERATION INSTRUCTIONS

GENERAL DESCRIPTION

Kenco Flat Glass Gauges are simple, rugged instruments engineered and constructed throughout to give you accurate
liquid level readings for the life of the vessel. We offer a complete range of gauges suitable for most applications. Like
any instrument, Kenco flat glass gauges must be installed, operated, and maintained with reasonable care and due regard
for the application, and the environment, if they are to give accurate readings over a long life.

INSPECTION & DELIVERY

Upon receiving the gauge, check all components carefully for damage incurred in shipping. Notify the shipping company
immediately of any such damage, and request a damage inspection. Confirm that the gauge model number and
pressure/temperature ratings (located on the nameplate) match the application conditions. Also, confirm that the gauge
materials are compatible with the process media and the environmental conditions around the gauge.

CAUTION – Kenco Gauge Glasses are not to be used for indicating the level of lethal substances as defined

by ASME Section VIII.

WELDING INSTRUCTIONS

Weld Pad Gauges are shipped loosely assembled and should first be entirely dismantled. The pad may then be used as
a template for laying out the vision slot which is to be cut through the wall of the vessel. If internal welding is to be
performed (recommended), the width and length of the slot can be increased by chalking a second cutout line ¼” away
from the scribed line obtained in tracing the vision slot. This will provide a suitable shelf in which to lay the bead, as
shown in the following drawing

To avoid buckling, the pad should be tack welded at intervals, both internally and externally, in accordance with
recognized welding procedures, before placing the continuous welds. As an added precaution against distortion, the
welding pad gauge can be assembled without gaskets, using a steel spacer instead of the gasket-glass-cushion
assembly. This spacer can be cut from bar stock 1¼” X ¾”. The length will be determined by the length of the gasket
recess. This procedure will increase the rigidity of the pad and minimize the possibility of distorting the glass seating
surface.

CAUTION – Standard weld pad gauges will withstand loadings due to the pressure within the gauge itself, but

they are not designed to replace the vessel strength lost when the vessel wall is cut. Kenco has
no control over the loading which the vessel will impose on the pad. It is therefore impossible to
rate welding pad gauges. The vessel fabricator must provide suitable vessel wall reinforcement
to prevent the pad from being distorted during welding, or while under operating conditions.
