Overview and Applications

The flow tester is a precision equipment for performing leak and flow measurements. Although it has been designed to be easily integrated in
Emdep test boards for testing water tubes, it is suitable for any other application where flow or leak measurements are required. Some typical
defects that can be detected by this equipment are:

  • Leakage on tubes.
  • Obstruction on tubes.
  • Etc

The Flow tester can detect defects such as pinched or leaky tubes.

Measurements and detection range

The images show measurements of the absolute flow drop in different kind of tubes tested at 1 bar. Tests have been performed with different internal diameter (mm) and different length (m) tubes.

The following images show the relative flow drop in different kind of tubes tested at 1 bar. The detection threshold represents the recommended minimum flow drop compared with non-defective tube. Tests have been performed with different internal diameter (mm) and different length (m) tubes.

Application Examples

Flow test

The second tube does not require any electro valve at the counterpart (only flow test), but the first one requires electro valves to check both branches sequentially.

Flow and Leak test

This example requires an electro valve in each counterpart to close the tubes during leak test.
