Someone told me this is a brochure for this flow meter: http://www.apator.com/uploads/files/Produkty/Przetworniki_przeplywu_do_cieplomierzy/MWN130-NC_MP130-NC/karta-mwn-nc130.pdf It is in Polish, so I can't be sure it is the right one. You can Google translate the text. The first paragraph, for example, comes out: "The heat flow transducer with a horizontal rotor axis, parallel to the water pipes with a low starting threshold. Thanks to modern structural solutions - technology It provides credibility indications and enables the development of atypical systems in intermediate positions without affecting its performance metrology. . . ." Anyway, this shows an exploded view of the instrument, etc. Perhaps this answers some of your questions. - Jed
