Description
вой прибор, определ етс момент вступлени морской волны в фазу экстремума, например в фаз возвышени поверхности жидкости, после чего даетс управл ющий сигнал на запуск генератора ультразвукового импульса. Импульс отражаетс от границы раздела сред: морска вода нефт на пленка и нефт на пленка-воздух. Приемные устройства принимают импульсы от передающих гидроакустических антенн и отраженные сигналы от границ раздела двух сред, после чего в устройстве определени временных интервалов вьпшсл етс разница во времени отраженныхThe device determines the moment when the sea wave enters the extremum phase, for example, in the phases of elevation of the liquid surface, after which a control signal is given to start the generator of the ultrasonic pulse. The impulse is reflected from the interface: seawater oil to film and oil to film to air. Receivers receive pulses from transmitting hydroacoustic antennas and reflected signals from the interfaces between two media, after which the time difference in the device for determining time intervals

Момент следующих посылок зондирующего импульса также определ етс устройством измерени параметров и следует приблизительно через полпёриода (или кратного времени полпериода) в фазе опускани поверхности жидкости . Устройство определени временных интервалов, как и в преды дущем случае, вычисл ет разницу во времени прихода отраженных от фазовых границ импульсов, по которой суд т о толщине пленки в фазе опускани поверхности жид ,кости. Оба сигнала поступают на вход запоминающего устройства и из него - в вычислительное устройство, где данные измерени за период морского волнени осред-г н ютс , поскольку пленка имеет разную толщину из-за неодинакового раст жени . В фазе воз&ышени поверхности жидкости происходит раст жение пленки, а в фазе опускани - сжатие.The time of the next probing pulse transmissions is also determined by the parameter measuring device and follows approximately half a period (or a multiple of half a period) in the phase of lowering the surface of the liquid. The device for determining the time intervals, as in the previous case, calculates the difference in the arrival time of the pulses reflected from the phase boundaries, by which the film thickness is measured in the phase of lowering the surface of the liquid and bone. Both signals are fed to the input of the storage device and from it to the computing device, where the measurement data for the sea wave period is averaged, since the film has a different thickness due to unequal stretching. In the phase of growth and increase of the liquid surface, the film is stretched, and in the phase of lowering - compression.
