Our newest addition to our stock of machinery

Weatherproof and permanently legible marking plates are an essential part of every differential pressure device to be able to clearly identify the measuring locations even after years or decades. In recent years, the requirements for this marking have increased steadily. Be it a certain font size, a certain font or other markings or logos. Our old needle embossing machine slowly reached its limits.

So last year we decided to retire it and buy a new machine. After careful consideration, we decided on a laser engraving machine. Not only is it much faster, and to the delight of our workshop staff significantly quieter, it can also display a wide variety of character sets simply and precisely using an integrated CAD-based interface.
Russian EAC signs with their Cyrillic letters are no longer a problem. Kazakh?-no topic! Greek lettering of the Orifice plates? – Sure!
Our laser engraving machine has already proven its worth. We can respond quickly and flexibly to the wishes of our customers and are no longer dependent on external engraving service providers.

Another important development step for our company.

ISO-TC30-SC2-WG18

… (a working group of the ISO – standards committee in the area of flow measurement with dP flow devices) has met at the BSI-Group headquarter in London shortly before Christmas to discuss the inclusion of throat taped-nozzles in the ISO 5167-3 standard. This was initiated by a group of researchers from NMIJ (National Metrological Institute of Japan). Being a longtime member of the DIN – standards committee, Dosch had sent two of its engineers to support the working group. They have achieved a pretty good result, which will shortly be given to ballot, and once it has passed this state, is estimated to enter into force middle of 2020.

BSI secretary David Michael, Dosch’s engineer Annette Kurzweg, TUV SUD NEL expert Dr. Michael Reader-Harris, Dosch’s engineer Daniela Hebler and NMIJ experts Noriyuki Furuichi and Yoshiya Terao.
