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.
UMX-2 Underwater Material & Coating Thickness Gauge The following procedure must be performed on the end cap o-rings before each use: 1. Clean all old silicone grease from o-rings and mating surfaces using paper towels. 2. Inspect o-rings for foreign material (sand, seaweed, hair, etc.), cracks, cuts, soft spots, or deformities. Replace o-ring if damaged. Inspect mating surfaces for scratches, rough spots, dents, or cracks. 3.
Dakota Ultrasonics 1.3 Disclaimer Applies to dual element transducers: Inherent in ultrasonic thickness measurement is the possibility that the instrument will use the second rather than the first echo from the back surface of the material being measured. This may result in a thickness reading that is TWICE what it should be. Responsibility for proper use of the instrument and recognition of this phenomenon rest solely with the user of the instrument.
CHAPTER TWO QUICK STARTUP GUIDE The UMX-2 is pre-configured at Dakota Ultrasonics with a specific and common setup. As a result, the gauge should be ready to measure once the transducer has been connected. The UMX-2 can use two different styles of transducers; dual element and single element membrane. As a result, the gauge will be configured according to the transducer style purchased, as follows: 2.
Dakota Ultrasonics 1) Referring to the diagram above, be sure the dongle and transducer are connected as illustrated. Note: in order for the UMX-2 to recognize the transducer that has been attached, it must be in the proper channel location. 2) Press and release the single button located on the end of the UMX-2. The displays should illuminate, and led lights will begin flashing.
UMX-2 Underwater Material & Coating Thickness Gauge 2.4 Quick Start (Dual Element) Procedure 1) Attached the transducer to the UMX-2. 2) Press and release the single button located on the end of the UMX-2. The displays should illuminate, and led lights will begin flashing. 3) The smaller of the two displays will begin scrolling the current configuration settings of the UMX-2, and an auto zero will be performed. 4) The UMX-2 is ready to begin making measurements.
CHAPTER THREE OVERVIEW Turn the UMX-2 on and off using the switch located on the bottom right corner of the keypad. When UMX-2 is initially turned on, a UMX-2 logo will be displayed, accompanied by lots of flashing led lights. The UMX-2 will attempt to ‘auto identify’ the transducer type that is connected, or display ‘NO PRB’ if the transducer cannot be identified. The following sections outline each scenario. Note: This section is primarily written as a basic startup guide only. 3.
UMX-2 Underwater Material & Coating Thickness Gauge 4 Digit , 8 Segment LCD Display The 4 digit display illustrated above, is considered the primary measurement display of the UMX-2. The following outlines the measurement display: The numeric portion of the display consists of 4 complete digits preceded by a leading "1", and is used to display numeric values, as well as occasional simple words, to indicate the status of various settings.

UMX-2 LT ON LT OFF LTAUTO MEMOFF UPGRAD UMX-2: This is a general utility menu for miscellaneous features and functions. The following is a brief explanation of each sub menu item. Refer to page 32 for further information on upgrading the UMX-2: • LT ON – Enables all the LED’s and display back lights.
Dakota Ultrasonics Top End Cap: Transducer Connectors The transducer connectors and single control button are located on the top end cap of the UMX-2. The transducer connectors are a special underwater Lemo “00”. Note: There is no polarity associated with connecting a dual element transducer. If a single element membrane style is connected, the dongle ‘must’ be plugged into the connector labeled in the diagram above , in order for the UMX-2 to ‘auto identify’ the single element probe type.
UMX-2 Underwater Material & Coating Thickness Gauge Probe Zero Disk The UMX-2 is equipped with an Auto Zero, which eliminates the user from having to manually perform a zero on a specified zero standard. However, a Manual Zero option has also been included with the UMX-2. This provides the user with the ability to reset the internal zero used for the auto zero as a reset option. Other than for the purposes of a safety mechanism, the Auto Zero feature will be used.
Dakota Ultrasonics RS-232 Connector Refer to Diagram: The RS-232 connector is a 2 pin female LEMO connector. It is designed to connect directly from the UMX-2 to a standard AT serial port on a PC or into the supplied Serial to USB converter cable . There are two cables supplied with the UMX-2; • 2 pin LEMO to 9 pin serial cable • 9 pin serial to USB converter cable. Note: This connector is also used to upgrade the UMX-2 to the latest version of firmware.
CHAPTER FIVE PRINCIPALS OF ULTRASONIC MEASUREMENT 5.1 Time versus thickness relationship Ultrasonic thickness measurements depend on measuring the length of time it takes for sound to travel through the material being tested. The ratio of the thickness versus the time is known as the sound velocity. In order to make accurate measurements, a sound velocity must be determined and entered into the instrument. The accuracy of a thickness measurement therefore depends on having a consistent sound velocity.
Dakota Ultrasonics The sound frequencies used in ultrasonic thickness measurement do not travel through air efficiently. By using a liquid couplant between the transducer and test piece the amount of ultrasound entering the test piece is much greater. 5.5 Temperature Temperature has an effect on sound velocity. The higher the temperature, the slower sound travels in a material. High temperatures can also damage transducers and present a problem for various liquid couplants.
UMX-2 Underwater Material & Coating Thickness Gauge Since pulse-echo only requires one reflection, it is the most sensitive mode for measuring weak reflections (flaws) typically found when measuring heavily corroded metals. V-Path Correction Dual element delay line transducers have two piezoelectric elements mounted at an angle on one end of the delay line. One element is used for transmitting sound, while the other element only receives sound.
Dakota Ultrasonics Dual Element Transducer in Echo to Echo mode Pulse Echo Coating Mode – Coating On (PECT) A custom hybrid combination mode using properties from the basic modes along with a group of special techniques and theoretical wave phenomena’s to measure coating and material thicknesses at the same time, while still retaining the ability to locate flaws and pits in materials. Therefore, the best description for this hybrid mode is Pulse-Echo Coating mode.
CHAPTER SIX SELECTING THE MEASUREMENT MODE 6.1 Which mode & transducer do I use for my application? High penetration plastics and castings The most common mode for these types of applications is pulse-echo. The UMX-2 has been optimized for cast materials. Cast iron applications require 1 - 5MHz frequencies, and cast aluminum requires higher frequencies from 7 -10MHz frequency. Plastics typically require lower frequencies depending on the thickness and make-up of the material.
Dakota Ultrasonics Thin materials Use pulse echo mode and a high frequency transducer for these types of applications. The most common transducers are the 7.5MHz and 10MHz models with extra resolution. The higher frequencies provide greater resolution and a lower minimum thickness rating overall. High temperature Use and select a special 2.25MHz and 5 MHz High temperature transducer for these types of applications. Both pulse-echo and echo -echo modes will also work for these applications.
CHAPTER SEVEN MAKING MEASUREMENTS The steps involved in making measurements are detailed in this section. The following sections outline how to setup and prepare your UMX-2 for field use. An automatic or manual zero must always be performed when using a dual element style transducer only. The single element membrane probe option uses a special multiple echo mode, and does not require zeroing. The auto zero is an off block electronic zero that does not require a zero reference block.
Dakota Ultrasonics or 1) Connect the probe to the UMX-2. 2) Be sure all couplant has been removed from the face of the transducer. 3) Press and release the single button located on the end of the UMX-2. The displays should illuminate, and led lights will begin flashing. 4) The smaller of the two displays will begin scrolling the current configuration settings of the UMX-2 in the following order: UMX-2, BATT (LO, ME, HI), Probe Type (1/2 2S or 1/2 5)…etc.
UMX-2 Underwater Material & Coating Thickness Gauge zero is being performed, the UMX-2 will put the gauge into pulse-echo mode automatically before performing the zero. Both zero options are broken down again as follows: The UMX-2 is equipped with two zero options: 1) Off Block Zero (Automatic Probe Zero) – When this feature is enabled the UMX-2 will do an electronic zero automatically, eliminating the need for a zero disk or block.

Once this occurs, the button can now be released.
UMX-2 Underwater Material & Coating Thickness Gauge 5) The UMX-2 is now calibrated and ready to begin taking readings. Preset Material Types & Velocities If the material velocity is known, the user may wish to simply enter the velocity number into the UMX-2, rather than have the UMX-2 calcula te the velocity value using a known thickness on a material sample. The steps for entering the velocity are outlined below: Using a Known Material Velocity 1) Press the MENU key once to activate the menu items tab.
Dakota Ultrasonics To calibrate the UMX-2 for a specific type of coating using the DakView3 utility software, refer to page 58 for a complete explanation on how to program a known coating velocity into the UMX-2.
CHAPTER EIGHT ADDITIONAL FEATURES & OPTIONS 8.1 Power Off The UMX-2 will power off automatically after approximately 4 minutes without receiving an echo (measurement). It should be noted that if the transducer face is not wiped clean, there’s a chance an echo can continuously be detected. If that happens, the gauge will remain on until the battery life is exhausted.
Dakota Ultrasonics When? The low settings may be necessary for noisy or granular cast materials. How do I know when to lower the gain? If the reading becomes sporadic and won’t settle down or resolve on a thickness value, the user can assume that the material is either very noisy aluminum, or g ranular cast iron. This would be a good time to change the UMX-2 to lower gain setting and see if the reading settles down and become stable.
UMX-2 Underwater Material & Coating Thickness Gauge 3) When the desired gain setting is displayed, immediately press and release the button to set the gain in the UMX-2. For this example, MED has been selected. 4) Press and hold the button to escape out of the sub menu options at any time. 8.3 Units (in/mm) The UMX-2 can be set to either English or Metric units.

The following describes each option: LT ON: Toggles both the display backlights and LED’s on.
UMX-2 Underwater Material & Coating Thickness Gauge 2) When UMX-2 is displayed, immediately press and release the button to enter the sub menu options. Again, the options will begin scrolling in a continuous loop (LT ON, LT OFF, LAUTO, MEM ON/OFF, UPGRAD). 3) When the desired light option is displayed, immediately press and release the butto n to set the option in the UMX-2. For this example, LT ON has been selected. 4) Press and hold the button to escape out of the sub menu options at any time.
CHAPTER NINE THRU PAINT MEASUREMENT TECHNIQUE 9.1 Introduction to Thru Paint Measurement (Dual Element Probes) The principle behind thru paint measurement is by measuring the time between two back wall echoes returning from the test material. Since both of these back wall echoes travel the same path through the paint or coating, the thickness of the coating is subtracted out of the measurement so that only the actual material thickness can be measured.
UMX-2 Underwater Material & Coating Thickness Gauge Disadvantages: Single element transducers are not capable of detecting pits and flaws with a digital thickness gauge, and are typically not used for corrosion inspections on blind surfaces. Since only one crystal is used to both send and receive sound waves, small defects that reflect very little sound energy back to the transducer are ignored, based on the noise created by the same crystal sending the sound wave.
CHAPTER TEN PULSE-ECHO COATING & COATING TECHNIQUES 10.1 Introduction to Pulse-Echo Coating Measurement (PECT) In the previous sections we’ve discussed the need for detecting pits and flaws (pulseecho) in materials, along with the requirement to measure through and eliminate errors caused by coated materials (echo-echo). Until now, both modes were needed in order accomplish both tasks.
UMX-2 Underwater Material & Coating Thickness Gauge saved for each individual reading, again offering confidence and detail for reporting purposes. The following procedure demonstrates how to enable PECT mode: Enabling PECT Mode 1) Press and hold the single UMX-2 button, located on the top end cap, until the top level menu options begin scrolling on the alpha display. Once this occurs, the button can now be released.
Dakota Ultrasonics feature. This enables the UMX-2 to obtain very accurate readings on coatings, eliminating potential errors incurred from slight differences in the manufacturing processes. The coating zero should be performed on an uncoated section of the same material or something similar. The procedure is outlined below: Performing a Coating Zero 1) Press and hold the single UMX-2 button, located on the top end cap, until the top level menu options begin scrolling on the alpha display.
UMX-2 Underwater Material & Coating Thickness Gauge 10.4 Coating Calibration (PECT) Known Velocity If the coating velocity is known, and other than the factory set velocity of 0.0850 in/µsec (2159 m/sec), the user may wish to program the UMX-2. In order to set the coating velocity, the DakView3 PC software must be used to create a setup, and upload the setup into the UMX-2. Refer to page 58 regarding setups.
CHAPTER ELEVEN DATA STORAGE – SETUP, EDIT, & VIEW FILES 11.1 Introduction to Grid and Sequential file formats The UMX-2 is equipped with two data file format options, GRID LOG and SEQ LOG. The GRID file format is very similar to a spreadsheet format found in popular software programs like Excel. A GRID is simply a table of readings. A location in a grid is specified by giving a row and column coordinate. The rows are numbered from 1 to 999 and the columns are labeled from A to ZZ (999 Rows & 52 Columns).
UMX-2 Underwater Material & Coating Thickness Gauge Sequential Log Formats Important Note: For the duration of this chapter, all references to GRIDS and SEQ LOGS should be considered synonymous with references to FILES. 11.2 Create New Log Field Definitions Coordinates or Start & Stop ID’s Grid: A grid is defined by using coordinates to define the Top Left and the Bottom Right corners of the grid. Alpha coordinates are horizontal across the top, and numeric coordinates are vertical down the side.
Dakota Ultrasonics corner of the grid, there will be an (X,Y) coordinate. Where X is an alpha column location across the top and Y is a numeric row location down the side. Use the same logic when choosing the lower right corner. An individual grid can be up to 999 rows and 52 columns. If the user attempts to create a grid that is larger than the stated boundaries, an error message box “OUT OF MEMORY“ will be displayed.
