Abstract

Изобретението се отнася до метод за измерване дебита на течащ флуид на базата на два ултразвукови сигнала, предавани последователно в противоположни една на друга посоки между два ултразвукови датчика. По метода се формират n хронометрирани сигнали CKi, като i приема стойности от 1 до n, които сигнали са взаимно фазово изместени с 2 /n, като първият хронометриран сигнал, обозначен с CLS, който се явява непосредствено след появяването на характеристичния участък на първия получен ултразвуков сигнал SIG1, е идентифициран и съхранен. Определя севремето t1, което съответства на сумата от интервалите от време на цяло число m последователни периоди между момента, в който се появява характеристичният участък на всеки от m периодите на сигнала SIG1, и момента, в който се появява следващият сигнал CLS. За сигнала SIG2, получен в противоположната посока, по подобен начин се определя времето t2,което отговаря на сумата от времевите интервали от m последователни периоди между момента, в който се появява характеристичният участък от всеки период, и момента, в който се появява следващият сигнал CLS. Отчита се разликата /t2-t1/ и от нея се извежда дебитът.
