Abstract

En fremgangsmåte for å detektere slampulser i en strom av slam omfatter overvåking av trykkendringen når strommen som inneholder pulsen passerer mellom to områder av roret med forskjellige tverrsnittsarealer. En anordning for bruk i en slik fremgangsmåte omfatter et legeme (2) omfattende en gjennomgående utboring for å passere boreslam gjennom den, forste og andre områder i utboringen, hvor det andre området har sterre tverrsnittsareal enn den forste, og en anordning (18) for å detektere forskjellen i trykk mellom slammet i det forste og det andre området.A method of detecting sludge pulses in a stream of sludge comprises monitoring the pressure change when the stream containing the pulse passes between two areas of the rudder with different cross-sectional areas. A device for use in such a method comprises a body (2) comprising a through-bore for passing drilling mud through the first and second areas of the bore, the second area having a larger cross-sectional area than the first, and a device (18) for to detect the difference in pressure between the sludge in the first and the second area.
