Technical system and method for online measuring and monitoring of the particle content in an injection water flow (6') in an underwater line (8). The system comprises a data gathering means, a data communication link (48) and a data receiving means comprising an image analysis apparatus (2) provided with: a water sample line (18) for throughput of a partial flow (6'') of the injection water flow (6'); a means of conveyance (24) connected to the water sample line (18) for transport of the partial flow (6''); a light-transparent flow portion (18') disposed along the water sample line (18); a camera (26) at the flow portion (18'); at least one light source (30, 32) for emission of light (34) via the flow portion (18') and into the camera (26); an electronic control means (36) for (a) control of the image recording of the camera (26); (b) reception of image material from the camera (26); and (c) transmission of the image material to the data receiving means; and at least one energy supply. The image analysis apparatus (2) is disposed in a water-tight housing (4) under water (6); wherein the water sample line (18) is connected to the underwater line (8) at a connection site (62) between a shipment site (50:64) for the injection water (6') and an injection well (56); wherein the data receiving means is located at a distance from the image analysis apparatus (2); and wherein the control means (36) of the image analysis apparatus (2) is connected to the remote data receiving means.
