The invention discloses a scanning method and apparatus suitable for scanning a pipeline or a process vessel in which a beam of gamma radiation from a source is emitted through the pipeline or the process vessel to be detected by an array of detectors, which are each collimated to detect gamma radiation over a narrow angle relative to a width of the emitted beam of gamma radiation.

Scanning method and apparatus

A method and apparatus for determining the location of a phase boundary such as a fill level, in a vessel. The method includes: providing at least one source of radiation capable of emitting radiation through a portion of the interior of the vessel; providing a plurality of radiation detectors, each detector being capable of detecting, within a part of the measurement range, radiation emitted by the source; and providing a data processing unit for calculation of the position of the phase boundary from the amount of radiation detected by the detectors, wherein the data processing unit calculates the position of the phase boundary from the amount of radiation detected by the detectors by:

Level measurement method and apparatus

An apparatus and method for the identification of different phases (-) in a multi-phase medium includes at least two arrays (A,B) of ultrasound transducers capable of transmitting and receiving ultrasound through the medium separating them. The method and apparatus is useful for the location of phase interfaces in vessels such as oil separators.

Level measurement system

A method and apparatus for performing a radiation scan of a structure involve arranging a source of penetrating radiation and a radiation detector at opposed ends of a radiation path through the structure, oriented in such a way that the source emits radiation along the path through the structure and the detector is capable of detecting the radiation after it has passed through the structure and monitoring the radiation emitted from the source that is detected by the detector. At least one continuous loop of a cable is mounted on the structure between at least two fixed locations on the structure so that the cable is movable along its length relative to the structure, and the at least one of the source of penetrating radiation and the radiation detector are fixed to the cable.
