Abstract
A method and system for taking a sample of ballast water. The method includes withdrawing a sample of ballast water via a tube inserted in a ballast water pipe, wherein the tube includes a sample inlet, and isokinetic flow is achieved via a pump that controls the flow of the sample ballast water through the tube inlet by comparing a flow of the ballast water pipe with a flow of the sample ballast water through the tube; and controlling the flow of water through the sample tube inlet when a flow of the ballast water pipe is sensed to be different; withdrawing a portion of the sample ballast water for testing; and returning remaining sample ballast water to the ballast water pipe.
