Снижение затрат, возможность поиска утечек и повышение эксплуатационных характеристик при использовании двухканальной модели

Дополнительная двухканальная/двухлучевая модель позволяет пользователю изменять конфигурацию системы для решения целого ряда практических задач измерения. Она может быть использована для измерения расхода в двух различных трубопроводах одним прибором, что значительно снизит затраты на точку измерения. Для уменьшения эффектов, связанных с искажением профиля скорости потока из-за завихрений и поперечных течений, используется установка двух пар ультразвуковых преобразователей в перпендикулярных плоскостях с целью формирования ортогональных акустических лучей. Для достижения максимального удобства в работе возможно использование различных комбинаций стационарных и накладных преобразователей и методов измерения в разных каналах. При решении любых задач, где используется данная модель расходомера DF868, непрерывно измеряются расходы жидкостей в обоих каналах, а также определяются их сумма, разность и среднее значение. При определении утечек расход измеряется в двух различных точках одного трубопровода и по разности его значений устанавливается наличие утечки.

Накладные преобразователи

Использование накладных преобразователей позволяет проводить измерения скорости рабочего потока в металлических, пластиковых и даже в покрытых бетоном трубопроводах без нарушения их целостности. Установка преобразователей на месте может быть осуществлена с помощью большого набора монтажных приспособлений, учитывающих материал и размеры трубопровода, тип преобразователя и метод крепления (например, с помощью цепей, металлической ленты, «липучки» — VELCRO®, магнитов, болтов или сварных стальных скоб с перфорированными металлическими лентами). Универсальная система монтажа накладных преобразователей включает в себя блоки-фиксаторы с линейкой для установки необходимого расстояния между датчиками с целью обеспечения высокой точности измерения. Кроме того, специальная система монтажа позволяет устанавливать миниатюрные накладные преобразователи на трубы диаметром от 13 до 50 мм.

Доброго дня всем!
На сбросе подготовленной подтоварной воды в море, по проекту установлен 12″ Provirl 77, но в силу обстоятельств, воды для его устойчивой работы недостаточно, у него порог чувствительности от 68 м3/ч. В итоге нашли на склде двухканальный Panametrics DF-868, без документации, будем пробовать его. Если у кого есть русскоязычный мануал — пршу скинуть. Заранее благодарен.
