Detector, for determining liquid taken from body of water, comprises support and active ingredient which changes action of predetermined materials in liquid or liquid stream to be investigated

摘要

Detector comprises a support and an active ingredient which changes the action the liquid or liquid stream to be investigated so that information about the material flowing through the detector is obtained. Detector comprises a support and an active ingredient which changes the action of predetermined materials in the liquid or liquid stream to be investigated so that information about the type and optionally the amount of the material flowing through the detector during the investigation is obtained. The speed and/or the direction of the liquid stream is also determined. The active ingredient is present in such an amount that the detection of the type and amount of material and/or the direction and/or speed of the liquid stream is possible over a required measured time period, with the proviso that the support may also be the active ingredient at the same time.
