CHAPTER ONE
INTRODUCTION - CARE & WARRANTY
The Dakota Ultrasonics model UMX-2 is an underwater ultrasonic thickness gauge
that measures with extreme versatility. It has the ability to simultaneously measure
coatings and material thicknesses while maintaining the ability to locate pits, flaws
and defects in the material. It can also use a combination of dual and single element
transducers, depending on the application requirements. Based on the same
operating principles as SONAR, the UMX-2 is capable of measuring the thickness of
various materials with accuracy as high as ± 0.001 inches, or ± 0.01 millimeters. The
principle advantage of ultrasonic measurement over traditional methods is that
ultrasonic measurements can be performed with access to only one side of the
material being measured.

1.1 Care & Maintenance
The UMX-2 housing is made of a clear PVC material that is very durable and well
suited for this application given the following conditions are followed:
• Keep the UMX-2 out of direct sunlight as much as possible to avoid any
potential ‘crazing’ or stress cracking, as well as discoloration.
• Protect the housing from impact.
• Submerge or rinse the enclosure and transducers in fresh water following use.
• Warning: Do not exceed the depth limitation of 1000 ft. Failure adhere to this
warning may result in leakage, potential implosion and serious injury.
The housing is sealed by o-rings, one on each end cap, which require meticulous
care. In order to maintain a watertight seal, the o-rings and their mating surfaces
must be clean, free of foreign material, and lubricated with silicone grease.
