TRANSCRIPT
…to solve a wide range of corrosion/erosion applications
Stable high temperature measurement…
The DMS 2 in combination with the HT 400A dual-element probe and armor
jacketed cable provide stable measurement on equipment having surface
temperatures up to 1000ºF (538ºC). Single-element high-temperature delay
line probes are also compatible. Use of the MIN CAP mode in combination with
FREEZE enables high temperature readings and A-Scans to be obtained quickly
without lift-off effects from uncoupling.
4 ways to measure without removing expensive protective coatings for
maximum flexibility…TopCOAT, Dual-Multi, S-Peak and S-Flank modes for
measuring through coatings (paint) without including the coating layer in the
digital thickness reading. Measurements are made between two consecutive
backwall echoes in all modes (except TopCOAT) and low amplitude coating
layer echoes are ignored. (See back page for more information on TopCOAT.)
Test materials with external pitting…
Small footprint dual-element probes are used to gain access to the bottom of
surface pits to measure true minimum remaining wall thickness on corrosion
prone equipment (i.e. piping, pressure vessels, storage tanks, plates). Obtain
stable thickness measurements on small diameter piping and tubing. Measure
in areas of limited access.
Find and capture thinnest reading during corrosion/erosion surveys…
The MIN CAP (MINimum CAPture) measurement mode finds and captures the
minimum thickness reading in a sequence of measurements. Both the live and
currently captured minimum thickness readings are displayed simultaneously.
An adjustable “time-out” period (1 to 10 seconds) prevents a new min cap
sequence from starting prematurely upon intermittent uncoupling.
The DMS 2 works with DME, DM4 Family, and
DMS dual & single element probes for
maximum flexibility and applications versatility.
Paint Coating
Coating Measurement
Total Thickness Measurement
Inside of pipe(showing corrosion)
…with new powerful expandedmeasurement capabilities and valuable options
TopCOAT(Patent No. 6035717) is a
new thickness measurement
technique utilizing 2 channels (one
channel measures the coating
thickness and one measures the total
thickness) that works like this:
• Measures the coating thickness
• Calculates the necessary coating
layer correction
• Measures the total thickness of
the coating layer and metal layer
• Deducts the calculated coating
correction value
• Displays the correct (metal only)
thickness
Advantages of the TopCOATmeasurement technique….
1. Measure through coatings (paint)
without including the coating
layer in the digital thickness
reading. Thinner measure-
ments are also possible than
when using multiple echo
techniques.
2. Allows normal “high gain”
corrosion thickness measure-
ment with maximum sensitiv-
ity to pitting. Measurement is
made at high gain levels and
from the initial pulse to the 1st
backwall reflection which is
proven to be the most effec-
tive way to measure equipment
having irregular backwall reflect-
ing surfaces (i.e. eroded/corroded
piping, tanks, pressure vessels…).
3. Measure the thickness of the
coating (paint) layer itself.
4. If no coating is present, measure
the thickness of materials from
one side without knowing their
sound velocity.
The current velocity
of the material un-
der test is measured
and set into the
instrument. Thick-
ness measurements
are made without knowing the sound
velocity of the material. Thickness of
various materials can be measured
without recalibration.
B-Scan is a simple inspection method enabling the user to
scan a part or area and produce a cross-sectional view. No
probes switching, extra cables or fixtures needed; the DMS
2 B-Scan works with ANY TG Probe. Easy to use soft key
controls enable the user to quickly configure the B-Scan
parameters to produce the best graphical views possible.
The DMS 2 goes further and allows the user to save the B-
Scan within its internal memory (user can save up to 1,100
B-Scans) and later transfer the B-Scan to our UltraMATE™
software for storage to disk, analysis and printing.

• Measures the total thickness of
the coating layer and metal layer
• Deducts the calculated coating
correction value
• Displays the correct (metal only)
thickness
Advantages of the TopCOATmeasurement technique….
1. Measure through coatings (paint)
without including the coating
layer in the digital thickness
reading. Thinner measure-
ments are also possible than
when using multiple echo
techniques.
2. Allows normal “high gain”
corrosion thickness measure-
ment with maximum sensitiv-
ity to pitting. Measurement is
made at high gain levels and
from the initial pulse to the 1st
backwall reflection which is
proven to be the most effec-
tive way to measure equipment
having irregular backwall reflect-
ing surfaces (i.e. eroded/corroded
piping, tanks, pressure vessels…).
3. Measure the thickness of the
coating (paint) layer itself.
4. If no coating is present, measure
the thickness of materials from
one side without knowing their
sound velocity.
The current velocity
of the material un-
der test is measured
and set into the
instrument. Thick-
ness measurements
are made without knowing the sound
velocity of the material. Thickness of
various materials can be measured
without recalibration.
B-Scan is a simple inspection method enabling the user to
scan a part or area and produce a cross-sectional view. No
probes switching, extra cables or fixtures needed; the DMS
2 B-Scan works with ANY TG Probe. Easy to use soft key
controls enable the user to quickly configure the B-Scan
parameters to produce the best graphical views possible.
The DMS 2 goes further and allows the user to save the B-
Scan within its internal memory (user can save up to 1,100
B-Scans) and later transfer the B-Scan to our UltraMATE™
software for storage to disk, analysis and printing.
