Effective thickness measuremets by non-contact thickness gauge UT-04 EMA (Delta)

NDE-specialists! Improve reliability and reduce the cost of NDE of metals!
This is the surest path to your success. Our apparatuses and methodology is reliable help on this way!


  • almost never required to strip rough, rust, paint;
  • never required to remove the protective coating thickness of 3 mm (work of stationary options is implemented with a clearance of up to 8 mm, in movement);
  • always without a contact liquid;
  • never required orientation of transducer (self-aligning effect);
  • time of one measurement is ten times less than measurement of the contact thickness gauges;
  • is equally successful both on ferrous and on nonferrous metals;
  • efficient at ambient temperature from - 40° С and up to + 650° С on the metal, and even under water;
  • cost price of the point of thickness measurement is 5 times cheaper than the cost price of the contact ultrasonic thickness gauges.


  • no expenses on cleanup, no expenses on the removal – restoration of the protective coating, on the couplant, its application, washing and degreasing and no expenses on the orientation of the transducer at the point of measurement;
  • no mechanical wear (abrasion) of the transducer, decreasing of the time of measurement in ten times (preparatory operations are not required);
  • ability to work in extreme conditions, when other devices are not functioning (severe corrosion, roughness and curvature, protective coating, high and low ambient temperatures and sensor operation under water).


  • memorized both the thickness and the echogram of the pulse signal received from opposite surface;
  • resolving power is potentially twice better;
  • in passing the apparatus detects imperfections in metal;
  • to monitor the walls one do not need to empty the vessel, pipe, etc.;
  • stable measurements when any other apparatuses are already nonserviceable;
  • manual scanning mode with thicknessgram on the display in real time;
  • to access databases via the Internet;
  • high accuracy of measurement:
    • poorly dependent on the roughness, curvature, and surface rust.
    • do not depend on the accuracy of the angular setting of the transducer.
    • echogram on the display immediately shows the inconsistency of measurement.

At thinning of the metal without fatigue changes therein (this is clearly defined in our accompanying coercimetry) – there is no reason to limit loads of structures and equipment
