The DM5E Family
The DM5E family is the latest generation of portable corrosion monitoring
thickness gauges form GE Sensing & Inspection 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 of
working environments, performing wall thickness measurements on pipelines,
pressure vessels and storage tanks in the oil and gas industry, as well as the
petrochemical and power generation sectors.


Three levels
There are three versions in the DM5E Family, which offer three levels
of functionality:
• DM5E Basic
• DM5E
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 GE corrosion thickness gauges 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 up-grade from DM5E Basic to DM5E in the field .
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 Com 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 key pad.
Both the basic and standard versions are field-upgradeable 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 reading s 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
