Abstract

Przedmiotem zgłoszenia jest układ do pomiarów punktowych w kanale zamkniętym, zawierający element pomiarowy, charakteryzujący się tym, że zawiera perforowaną płytę (1), która ma kształt odpowiadający przekrojowi kanału zamkniętego, a element pomiarowy (2) ma kształt wydłużonego pręta o średnicy mniejszej od średnicy perforacji w perforowanej płycie (1), ponadto element pomiarowy (2) na pierwszym końcu ma czujnik (2a), a drugi koniec elementu pomiarowego (2) połączony jest z układem pozycjonującym (3) zintegrowanym z kontrolerem (3a) regulującym położenie elementu pomiarowego (2) względem perforowanej płyty (1) w trzech kierunkach (x,y,z) oraz połączony jest z urządzeniem pomiarowym (4). Kolejnym przedmiotem zgłoszenia jest sposób pomiaru parametrów płynu w przekroju kanału zamkniętego w warunkach przepływu oraz nadciśnienia z wykorzystaniem układu, obejmujący etapy: a) odcięcie kanału zamkniętego za miejscem pomiarowym, b) umieszczenie perforowanej płyty (1) w miejscu pomiarowym w przekroju poprzecznym kanału zamkniętego, c) umieszczenie elementu pomiarowego (2) w świetle wybranej perforacji w perforowanym elemencie zewnętrznym (1), wprowadzenie go przez perforację i dokonanie pomiaru, d) przesłanie sygnału do urządzenia pomiarowego (4), e) wycofanie elementu pomiarowego (2) na zewnątrz kanału zamkniętego po dokonaniu pomiaru, f) powtórzenie czynności c), d) i e) dla kolejnych perforacji.The subject of the application is a system for point measurements in a closed channel, comprising a measuring element, characterized in that it comprises a perforated plate (1) which has a shape corresponding to the cross-section of the closed channel, and the measuring element (2) has the shape of an elongated rod with a diameter smaller than the diameter of the perforation in the perforated plate (1), furthermore the measuring element (2) has a sensor (2a) at the first end, and the second end of the measuring element (2) is connected to a positioning system (3) integrated with a controller (3a) regulating the position of the measuring element (2) relative to the perforated plate (1) in three directions (x, y, z) and is connected to a measuring device (4). Another subject of the application is a method of measuring fluid parameters in a cross-section of a closed channel under flow and overpressure conditions using a system comprising the steps of: a) cutting off the closed channel behind the measurement point, b) placing a perforated plate (1) at the measurement point in the cross-section of the closed channel, c) placing a measuring element (2) in the light of a selected perforation in the perforated external element (1), inserting it through the perforation and taking the measurement, d) sending a signal to the measuring device (4), e) withdrawing the measuring element (2) outside the closed channel after taking the measurement, f) repeating steps c), d) and e) for subsequent perforations.
