1. Metodologija za otkrivanje i lokalizaciju istjecanja, u podzemnim cjevovodima, na temelju načela mikrovalne reflektometrije, pomoću uređaja koji se sastoji od reflektometrijske jedinice (1), elektroničkog kalkulatora (2), osjetnog elementa (3) izrađenog od električno vodljivog materijala postavljenog na površinu prometnice u skladu s podzemnom metalnom cijevi (5), pribora (9) za električnu vezu između reflektometrijske jedinice (1) i podzemne cijevi (5) i pribora (7) za električnu vezu između reflektometrijske jedinice (1) i osjetnog elementa (3), te je navedena metodologija naznačena time što sadrži slijedeće korake: (i) postavljanje osjetnog elementa (3), koji zajedno s metalnom cijevi (5) djeluje kao vod za prijenos pri čemu se električni spoj (6) između osjetnog elementa (3) i reflektometrijske jedinice (1) ostvaruje putem koaksijalnog kabela (7) s električnom impedancijom približno jednakom izlaznoj impedanciji reflektometrijske jedinice (1) pri čemu se električni spoj (9) ostvaruje preko unipolarnog kabela koji se spaja između točke pristupa cijevi čime se omogućuje električni kontinuitet između cijevi i reflektometrijske jedinice (1); (ii) slanje elektromagnetskog signala iz jedinice (1) koji se širi preko prijenosne linije koja se sastoji od osjetnog elementa (3) i podzemne cijevi (5); (iii) otkrivanje reflektometrijskog signala; (iv) vizualizaciju i interpretaciju reflektometrijskog signala kao funkcije vremena ili, alternativno, kao funkcije odgovarajuće vidljive udaljenosti koja je funkcija dielektričnih svojstava tla između navedene podzemne cijevi (5) i navedenog osjetilnog elementa (3), s posebnim naglaskom na gubitak vode; (v) individualizaciju značajnih dielektričnih promjena povezanih s otkrivenim reflektometrijskim signalom (tipično one koje odgovaraju prisutnosti relativnog maksimuma ili minimuma) s posebnim naglaskom na gubitak vode; (vi) lokalizaciju mogućeg istjecanja na udaljenosti L1 od mjerne točke i L2 od završnog elementa (3); (vii) kalibraciju između referentne poznate udaljenosti L1 + L2 i odgovarajuće izmjerene vidljive udaljenosti radi procjene ispravne prostorne lokalizacije istjecanja; (viii) implementaciju specifičnog filtriranja signala radi poboljšanja interpretacije reflektometrijske detekcije.
2. Uređaj za izvođenje metodologije prema patentnom zahtjevu 1 naznačen time što sadrži reflektometrijsku jedinicu (1), elektronički kalkulator (2), osjetni element (3) izrađen od električno vodljivog materijala postavljenog na površinu prometnice u skladu s podzemnom metalnom cijevi (5), unipolarni kabel (9) za električnu vezu između reflektometrijske jedinice (1) i podzemne cijevi (5) i koaksijalni kabel (7) s električnom impedancijom približno jednakom izlaznoj impedanciji reflektometrijske jedinice (1) za električnu vezu između reflektometrijske jedinice (1) i osjetnog elementa (3).
