Abstract: A system and a method for measuring a signal propagation speed in a liquid (2) contained in a vessel (1) or in a gaseous medium (4) contained in the same vessel (1) above the surface of the liquid (3) are proposed. At least one transmitter (x1) is arranged to transmit a first signal in a first direction which is at an acute or right angle to a first reflective surface (3; 6) and along which a variation or a gradient in the signal propagation speed is expected, wherein the first reflective surface (3; 6) reflects the first signal so that it travels in a second direction is received by a first acoustic or electromagnetic receiver (x1, x4). The at least one transmitter (x1, x3) is further arranged to transmit a second signal in a predetermined third direction which is at an acute angle (α) to the first direction, where the first or a second reflective surface (3; 6) reflects the second signal so that it travels in a predetermined and angular fourth direction with respect to the first or second reflective surface (3; 6) and is received by the first or a second acoustic or electromagnetic receiver (x1, x2, x4, x5). The speed of sound is then determined under the assumption that both the first and the second signals travel at the same average speed. The determination is based on a first time of flight (t1) of the first signal, a second time of flight (t2) of the second signal and a corresponding known first and second distance, wherein the first and second distance are different from each other and are either a distance between the first and the second receiver or a known geometric dimension (D) of the vessel.

Abstract: A ballast water treatment apparatus (100) and a ballast water treatment system (1) having a ballast water treatment apparatus (100) are provided. The ballast water treatment apparatus (100) includes a ballast water transport line (10) configured to transport ballast water between a first location (A) and a second location (B), the transported ballast water being passed through at least one injector (20), and a plasma generation device (30) configured to be fed with a feed gas comprising oxygen, and configured to generate a feed gas plasma (35) by a non-thermal discharge in a discharge area (36) to provide a treated gas at a treated-gas outlet (37). The injector (20) comprises a liquid passage (21) having an area (22) constructed such as to increase a velocity of the passed-through water in a region (26) of increased velocity, and an injector gas inlet (25) provided in the region (26) of increased velocity. The treated-gas outlet (37) is in gaseous connection with the injector gas inlet (25).

Abstract: A system and a method for non-intrusive and continuous level measurement of a liquid are described, where the liquid is enclosed by a solid wall of a vessel (41). The system comprises an ultrasonic transmitter (48) for generating an ultrasound wave and for emitting it into the vessel wall, an ultrasonic receiver (49) for receiving the ultrasound wave through the vessel wall, and at least one electronic control and data processing unit (6) for controlling operation of the transmitter (48) and of the receiver (49) and for determining the liquid level (H) from a time of flight of the ultrasound wave. The transmitter (48) is a frequency-tunable transmitter which is placed at a first position at the outside of the vessel wall and below the level of the liquid surface (44) in such a way that the transmitter (48) is able to emit the ultrasound wave as a primary Lamb wave into the vessel wall so that a part of the primary Lamb wave leaks from the vessel wall into the liquid in form of a pressure wave (43) in an inclined and upward direction towards the liquid surface (44). The receiver (49) is placed at a second position at the outside of the vessel wall and below the level of the liquid surface (44) in such a way that the receiver (49) is able to receive a secondary Lamb wave which is generated by the pressure wave (43, 45) hitting the vessel wall after having been reflected by the liquid surface (44). The at least one electronic control and data processing unit (6) is adapted to repeatedly determine the time of flight (t) of the pressure wave (43, 45), change the ultrasonic frequency (f) of the transmitter (48) until the determined time of flight reaches a minimum (tmin), and determine the liquid level (H) based on the relationship that the minimum time of flight (tmin) equals the length of the travel path of the pressure wave (43, 45) divided by the speed of the pressure wave in the liquid (cL).
