Technical system and method for online measuring and monitoring of the particle content in an injection water flow (') in an underwater line (). The system comprises a data gathering means, a data communication link () and a data receiving means comprising an image analysis apparatus () provided with: a water sample line () for throughput of a partial flow (&#x2033;) of the injection water flow (&#x2032;); a means of conveyance () connected to the water sample line () for transport of the partial flow (&#x2033;); a light-transparent flow portion (&#x2032;) disposed along the water sample line (); a camera () at the flow portion (&#x2032;); at least one light source () for emission of light () via the flow portion (&#x2032;) and into the camera (); an electronic control means () for (a) control of the image recording of the camera (); (b) reception of image material from the camera (); and (c) transmission of the image material to the data receiving means; and at least one energy supply. The image analysis apparatus () is disposed in a water-tight housing () under water (); wherein the water sample line () is connected to the underwater line () at a connection site () between a shipment site () for the injection water (&#x2032;) and an injection well (); wherein the data receiving means is located at a distance from the image analysis apparatus (); and wherein the control means () of the image analysis apparatus () is connected to the remote data receiving means.
