Fluid analysis

A method for analyzing a fluid, the method comprising:

• emitting light from a light source;
• transmitting the emitted light through a first optical transmission means to at least one measurement device, which at least one measurement device comprises at least a part of the fluid;
• illuminating the at least one measurement device with the transmitted light;
• and
• transmitting shadowed or reflected light from the fluid when the at least one measurement device is illuminated to one or more image capturing device using a second optical transmission means, wherein the one or more image capturing device is configured to capture an image of the fluid in the measurement device based on the transmitted information about the fluid;
• and
• wherein the light source and the one or more image capturing device are remotely arranged from the at least one measuring device.

A method for analysis of a fluid in a conduit using an apparatus, the apparatus being located in the conduit, the apparatus comprising a flow cell formed with a fluid inlet and a fluid outlet, and the apparatus located within the conduit further comprising a flow restriction arrangement, at least one optical transmission element and at least one optical receiving element, the method comprising:

• generating an increased head loss between the fluid inlet and the fluid outlet when a part of the fluid in the conduit flows through the apparatus;
• transmitting light emitted from a light source through the at least one optical transmission element so that it passes through at least a section of the fluid flowing through the flow cell;
• receiving, with the at least one optical receiving element, the light after passing through the fluid in the flow cell;
• and
• transmitting, using the at least one optical receiving element, the received light to an analyser so that the fluid can be analyzed.
