The logging tool is equipped with injector enabling to create in the streaming water a colour mark using the food dye Brilliant Blue (E133) as a tracer. A pair of photometric sensors is located in the axis of the flowmeter in a distance 5 and 10 cm above and below the special outlet nozzle of the injector. The proper function and reliability of the logging tool was checked in the model of the well under laboratory conditions. The flow velocity determined by the flowmeter with the volumetric flow rate using the calibrated glass cylinder and the stop-watch was compared. The results of the laboratory tests have been summarised in the paper.
