Magnetic Level Gauge for Liquid Applications
Extruded Process Connections
K-TEK off ers extruded connections for the process
connections on most chambers. The extrusion process
benefi ts include:
Stronger connections
Eliminates the need of post weld straightening
Provides full bore process connection
Eliminates “sink-in” distortion that interferes with
fl oat movement
Improves quality, operation and reliability
Additional connections can be extruded for level
switches, pressure switches, pressure transmitters, etc.
Meets ANSI B31.1, B31.3, and section VIII - Div. 1
The weld does not protrude into the chamber

Principle of Operation
A hermetically sealed fl oat with an internal magnetic ring is housed in a non-magnetic fl oat
chamber. The fl oat will move up and down in the chamber as level rises or falls in the vessel
on which it is attached.
A magnetic, highly visible “shuttle” or bar graph indicator, encapsulated in a hermetically
sealed glass tube, is attached in a scale housing to the outside of the fl oat chamber. It
indicates the liquid or interface level without being in contact with the process fl uid.
K-TEK fl oats are designed and weighted so that the center of the magnet assembly is at the
true fl uid level for absolute accuracy.
Coating, plating, fouling, fugitive emissions and leaks of hazardous material problems are
eliminated.
Problems with colorless or dirty fl uids are solved since the indicator is non-contact.
No gauge glasses to clean. No leaks to repair.

The Ultimate Level Measurement System:
The K-TEK AT200 and AT600 are highly
accurate devices designed to be used with
the KM26 Magnetic Liquid Level Gauge
Series, or any other Magnetic Level Gauge.
It is designed to provide continuous level
indication, and transmission of an analog
signal for monitoring or control. The unique
magnetostrictive design allows increased
level sensing resolution, which is more than
100 times greater than a conventional reed
switch type sensing device.
