Waygate Technologies DM5E Specifications

DM5E corrosion

thickness gauges

A range of high-performance, reliable

and easy-to-use instruments

The DM5E family

The DM5E family represents the highest standard of

portable corrosion monitoring thickness gauges from
Waygate Technologies. It offers significant improvement
in performance over 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 the petrochemical and
power generation sectors.

Choose from three levels of functionality.

DM5E Basic, DM5E, or DM5E DL.

The DM5E Basic

The rugged housing of the DM5E Basic is common to all versions. It is

ergonomically designed 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 is carried out with
one hand via a user-friendly interface. This is a sealed, watertight and
dust-proof membrane keypad, which features a minimum of function keys
and arrow keys. Navigation through menus is simple and intuitive. The
basic version incorporates a wide range of features, including Min/Max
capture, B-Scan generation, alarms, and differential thickness measurement
to allow instant comparison between measured and nominal 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 DL

The 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 can be 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 field-upgradable
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 to activate and set functional control
and four arrow keys for adjusting parameter values
and for navigating through the intuitive single-level
menu. The keypad allows access to all calibration,
set-up and measurement display modes of 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-performance
probes

A new set of ultrasonic probes has been developed

for the DM5E family to provide the instruments with
optimized performance, even at very high temp­eratures. The DA5xx series includes a 5-MHz
standard probe for general purpose applications, a
2-MHz version for high penetration and a 7.5-MHz

fingertip probe. A newly developed 5-MHz

high-temperature 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-multi
measurement. Virtually all components and struc­tures subjected to thickness measurement will
have some kind of protective coating. Such coatings,
including paint, contribute significant 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-proven dual-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 to store up to a massive 50,000 reading in
grid and linear files. This makes the measurement
data available for further processing. 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
in different fixed-format reports. Typically, these
can be color histograms, where ranges of
measured values are color-coded, or color can be
used to highlight the distribution of minimum/
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 of measurement displays.

These include:

Normal

The thickness value appears as large
digits in the center of the display.

MIN Scan

A minimum thickness scan that allows
the user to run the probe over the wall
surface. After the evaluation period, the
minimum material thickness measured
is displayed.

MAX Scan

A maximum thickness scan that is exactly
the same as a MIN Scan apart from
the fact that the maximum thickness
measured is displayed.

DIFF/RR%

Compares the measured thickness with
a user-specified 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-Scan showing minimum thickness
values. The graph is derived by measuring
and recording at 1 point per second.
