Projekt Lilama 69-3 in Song Thao, Vietnam

In Vietnam, a rapidly emerging economic nation, you will find state-of-the-art plants whose technical standard is often higher than that of European plants. In their search for innovative technology, the responsible planners and operators of Vietnamese plants have already discovered Poettersonden®, which offer considerable advantages compared to other measuring systems.

Part of the Lilama 69-3 project in Song Thao, Vietnam:

  • Permanent pressure loss (below detection limit)
  • No inlet sections required
  • High accuracy
  • Insensitive to dirt
  • Virtually maintenance-free
  • No counter bearing required
  • Extreme reliability

These were the reasons for the first installations of Poettersonden®.

Based on the positive experiences, the operators have decided to use Poettersonden® as standard measurements in other plants as well. The responsible Vietnamese business partners work extremely conscientiously and precisely and do not use anything without knowing the exact technology used. With the first orders, the operator therefore ordered a week-long intensive training of his employees by the inventor of the Poettersonde®, Dipl. Ing. Friedrich Pötter. This clever decision now enables the operator to find and remedy unlikely faults in our measuring method quickly and confidently.

Dipl. Ing. Friedrich Pötter training in the classroom at XI MÄNG THAO. The training was opened with the discussion of other measuring methods, their applicability with all advantages and disadvantages.

This was followed by the theory about Poettersonden®, with the Flow Computers C 621 and all associated components


This was followed by training directly in the field at one of the installed Poettersonden®.

The training was held by Dipl. Ing. Friedrich Pötter in English. It was simultaneously translated into Vietnamese by the charming Miss Duyen Nguyen Hong. It was a really great achievement to translate unusual technical terms from English into Vietnamese over several days. You did very well, dear Duyen. Thank you very much for that!

The training on the flow computer C 621 could then take place in an English direct dialogue with the extremely dedicated electonic engineer Mr. Phung Van Trung, who spoke the best English. This Dipl. Ing. Friedrich Pötter perforated into the deepest technical detail. It was very pleasant to get into the depth of the special technology of the Flow Computer C621, which differs considerably from conventional flow computers, with such an interested partner.

After this intensive training by Dipl. Ing. Friedrich Pötter the employees of Lilama and XI MÄNG THAO are now effortlessly able to install Pöttersonden® and Flow Computer C 621 with all components perfectly, to put them into operation themselves, but also to find and correct faults immediately.


Deputy General Director Pam Xuang Dang:
"An investment is always justified if it is fully amortized within 2 years through energy savings and/or quality improvement".

Mr. Dang's motto explains why you find so much modern and innovative technology in this facility. He was also the one who absolutely wanted very intensive training for his employees on the technology used.

Certainly a wise decision!

Mr. Doan Ngoc Lam, Chief of Representative and EPC contractor, is the plant's operations manager and one of the key decision makers. He was very committed to the use of Poettersonden® to improve the product quality and energy efficiency of his plant.

Managing Director Dipl. Ing. Friedrich Pötter would like to express his sincere thanks for the trust placed in him, the excellent hospitality and the excellent cooperation.
