K-TEK offers extruded connections for the process
connections on most chambers. The extrusion process
benefits include:
 Stronger connections
 Eliminates the need of post weld straightening
 Provides full bore process connection
 Eliminates “sink-in” distortion that interferes with
float 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 float with an internal magnetic ring is housed in a non-magnetic float
chamber. The float 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 float chamber. It
indicates the liquid or interface level without being in contact with the process fluid.
K-TEK floats are designed and weighted so that the center of the magnet assembly is at the
true fluid level for absolute accuracy.
Coating, plating, fouling, fugitive emissions and leaks of hazardous material problems are
eliminated.
Problems with colorless or dirty fluids 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.
