DM5E corrosion
thickness gauges

A range of high-performance, reliableand easy-to-use instruments

The DM5E family

The DM5E family represents the highest standard of portablecorrosion monitoring thickness gauges from Waygate
Technologies. It offers significant improvement in performanceover previous corrosion thickness gauges in terms of better
thickness measurement stability and repeatability at
normal and elevated temperatures. It has been designed for
operation in the harshest working environments, performing
wall thickness measurements on pipelines, pressure vessels
and storage tanks in the oil and gas industry, as well as in thepetrochemical and power generation sectors.

2Choose from three levelsof functionality
DM5E Basic, DM5E, or DM5E DL

The DM5E Basic

The rugged housing of the DM5E Basic is common to all versions. It is ergonomicallydesigned with a weight of just 223g, including its AA batteries, which allow up to 60
hours of operation. The basic version is specified to EN 15317 and features an LCD data
display, which is backlit to be visible in all lighting conditions. Instrument operation iscarried out with one hand via a user-friendly interface. This is a sealed, watertight anddust-proof membrane keypad, which features a minimum of function keys and arrowkeys. Navigation through menus is simple and intuitive. The basic version incorporates
a wide range of features, including Min/Max capture, B-Scan generation, alarms, anddifferential thickness measurement to allow instant comparison between measured andnominal thickness.

The DM5E

The DM5E incorporates all the features of the DM5E Basic but also offers the DUAL MULTI
operating mode. This has been used in previous corrosion thickness gauges from
Waygate Technologies and has proved invaluable in measuring thickness of metal
through coatings. There is no need to remove the coating at the measuring point, saving
time and money. Users can upgrade from DM5E Basic to DM5E in the field.

The DM5E DLThe DM5E DL is identical to the DM5E but features a built-in datalogger supporting
grid-style data file formats. This is capable of holding up to 50,000 readings. Files canbe transferred to a PC by means of a Mini USB port. Files can also be imported directly
into Microsoft Excel through a macro. All alphanumeric data for filenames and notes
is directly entered via the keypad. Both the basic and standard versions are fieldupgradable to become DL versions.

User-friendly operator interface

All versions of the DM5E have the same user-friendly
operator keypad interface. This has a central mode
key, a calibration/on/off key, two function arrow keys toactivate and set functional control and four arrow keys foradjusting parameter values and for navigating throughthe intuitive single-level menu. The keypad allows accessto all calibration, set-up and measurement display modesof the instrument. With the DL version, a file display mode
allows users to create and store thickness readings in files.
All calibration is menu-driven and the operator is guided
through every step. There is a built-in calibration reminder,
which can be set to remind the user to calibrate after a
specified number of measurements or after a given
time period.

New range of high-performanceprobesA new set of ultrasonic probes has been developed for theDM5E family to provide the instruments with optimized
performance, even at very high temperatures. The DA5xx
series includes a 5-MHz standard probe for general purposeapplications, a 2-MHz version for high penetration and a
7.5-MHz fingertip probe. A newly developed 5-MHz hightemperature probe offers an operating range from -10°C up
to +204°C. (Standard probes operate to 70°C.)

Thickness measurement
under coating

Both the DM5E and the DM5E DL offer dual-multimeasurement. Virtually all components and structuressubjected to thickness measurement will have some kind ofprotective coating. Such coatings, including paint, contributesignificant error to thickness measurements of underlying
metal walls when using conventional methods. In addition,
the removal of coatings, and their subsequent reapplication,
involves considerable cost and time. With the field-provendual-multi feature there is no need to remove any protective
coating. It is only necessary to select dual-multi mode, place
the probe in position and take the measurement.

Flexible data processing

The DM5E DL has a built-in datalogger, with a capacity tostore up to a massive 50,000 reading in grid and linear files.
This makes the measurement data available for furtherprocessing. Using our UltraMATE software, measurement
data files can be transferred from the instrument to a PC,
where they can be stored and, if required, printed out indifferent fixed-format reports. Typically, these can be color
histograms, where ranges of measured values are colorcoded, or color can be used to highlight the distribution ofminimum/maximum limit values exceeded. Data can also
be pasted into Windows Clipboard for easy transfer into
spreadsheet and word processing applications.

A range of measurement displays
All versions of the DM5E offer a range ofmeasurement displays.
These include:

NormalThe thickness value appears as large digits inthe center of the display.

MIN Scan minimum thickness scan that allows the userAto run the probe over the wall surface. Afterthe evaluation period, the minimum material
thickness measured is displayed.

MAX Scan maximum thickness scan that is exactly theAsame as a MIN Scan apart from the fact that themaximum thickness measured is displayed.

DIFF/RR%
Compares the measured thickness with a userspecified nominal thickness. The dimensional
difference between the two values is displayed,
as is the percentage difference.

B-ScanDisplays a graphic representation of a B-Scanshowing minimum thickness values. The graphis derived by measuring and recording at 1 point
per second.
