Небольшие раз-меры и вес, встроенный блок аккумуляторов и универсальное зарядное устройство обеспечивают высокую гибкость применения этого расходомера, практически, в любых задачах измерения расхода жидких сред.

Высокая точность измерения расхода двухфазных и чистых жидкостей

Запатентованная корреляционная времяимпульсная технология измерения расхода Correlation Transit-Time™ и цифровая обработка сигналов, реализованные в TransPort PT878, значительно увеличивают отношение сигнал-шум, обеспечивая точное, без дрейфа нуля измерение расхода жидкостей, которые содержат вторую фазу – захваченные потоком частицы или газовые пузырьки. Расходомер TransPort надежно работает в этих и других сложных условиях, где традиционные расходомеры не действуют. Расходомер TransPort PT878 также позволяет точно измерять расход в идеально чистых жидкостях, не содержащих «отражатели», где Допплеровские расходомеры работать не могут. Расходомер TransPort пригоден для использования, как в случае обычных задач применения времяимпульсного метода, так и в большинстве других задач, где традиционные время-импульсные расходомеры «встречаются» со значительными трудностями.

Простота и легкость использования

Возможность выполнения первых измерений расхода в пределах нескольких минут после открытия упаковки говорит о легкости использования расходомера TransPort. Просто введите параметры объекта, прикрепите УЗ преобразователи на трубу, установите расстояние между ними, и «процесс пошел». При этом нет необходимости в дополнительном оборудовании, а также во врезке в трубопровод. Опытный пользователь может выполнить множество различных измерений за один рабочий день. Расходомер TransPort PT878 – это идеальное средство для всех видов обследований, связанных с измерением расхода.

PC совместимый программный интерфейс

Расходомер TransPort PT878 обеспечивает стабильную точность измерения расхода без загрязнения и утечек измеряемой среды. Расходомер TransPort PT878 не имеет движущихся деталей, которые подвержены износу, или сужений, приводящих к засорению трубы, и не требует регулярного технического обслуживания. Для удовлетворения жестким требованиям промышленного применения доступен широкий спектр УЗ преобразователей с различными рабочими частота-ми, материалами конструкции, рабочими температурами и размерами. Для обеспечения контакта накладных УЗ преобразователей с трубой доступны различные зажимные приспособления для разных труб и размеров УЗ преобразователей. Эти зажимные приспособления реализуют различные способы крепления к трубе, включая цепи, металлические ленты, ленты Velcro® и магнитные зажимы.

Алфавитно-цифровой и графический ЖК-дисплей завершает картину

Большой многофункциональный ЖК-дисплей позволяет представлять измеренные данные, как в алфавитно-цифровом, так и в графическом формате. Кроме того, он помогает легко выполнять программирование, представляя меню программы, которое обеспечивает ввод данных и выбор функций. Стандартные функции представления данных в буквенно-цифровом формате включают в себя отображение скорости потока, объемного расхода и энергии теплового потока, а также суммарного количества в английских или метрических единицах измерения. В графическом режиме ЖК-дисплей показывает, как данные в реальном масштабе времени, так и записанные данные. При этом справа на дисплее воспроизводится график, который полезен для просмотра данных и наблюдения за трендами на объекте.

Экономически эффективное решение

Для того чтобы быть действительно полезным, портативный расходомер должен быть экономически выгодным для владельца и работать в любых полевых условиях. Расходомер TransPort PT878 разработан так, чтобы оставаться в эксплуатации в течение многих лет. Это устройство, полностью изготовленное из твердотельных элементов, практически не изнашивается или не нуждается в сервисе, обеспечивая минимальное время простоя и низкие затраты на техническое обслуживание.

Расходомер TransPort PT878 реализует времяимпульсный метод измерения расхода

При использовании этого метода, два УЗ преобразователя служат по очереди как генераторы и приемники УЗ сигналов. После установки их на трубе, они акустически связаны друг с другом, т.е. один из УЗ преобразователей может принимать УЗ сигналы, переданные другим УЗ преобразователем, и наоборот. Во время работы каждый из УЗ преобразователей функционирует как генератор, генерируя определенное число акустических импульсов, а затем как приемник такого же числа импульсов. Интервал времени между подачей и приемом УЗ сигналов измеряется в обоих направлениях. Когда жидкость в трубе неподвижна, время распространения этих сигналов по потоку равно времени распространения сигналов против потока. Когда жидкость течет по трубе, время распространения сигналов по потоку меньше времени распространения сигналов против потока. Разность этих времен распространения пропорциональна скорости потока жидкости, а ее знак указывает направление потока.

  Diagnostics and Troubleshooting The TransPort PT878GC is a reliable instrument that is easy to maintain. It will provide accurate flow measurement readings as long as it is operated as described in this manual. If problems do arise with the electronics, transducers or the flowcell, the TransPort displays an error message specifying the possible problem.
• Page 184
  “Error.”The Error Code messages are only general descriptions of the possible problems. Use Table 8 to isolate and remedy the problem. If you are unable to remedy the problem, contact Panametrics Sensing. Note: We suggest that, in order to isolate the indicated problem more easily, you obtain a test flowcell.

  Pipe Problems Improper pipe conditions and/or flowcell installation can cause problems with measurement of the gas flow. Contact Panametrics Sensing if you cannot solve pipe-related problems. By far, the most common pipe problems are the following THE COLLECTION OF MATERIAL AT THE TRANSDUCER LOCATION(S). Accumulated debris at the transducer location(s) will interfere with transmission of the ultrasound signals.
• Page 189
  If corrosion is suspected, remove the transducer from the flowcell and carefully inspect the electrical connector and the transducer surface for roughness and/or pitting. Any transducer damaged in this manner must be replaced. Contact Panametrics Sensing for information on transducers in materials suitable for the application.

  Appendix B. B.1.0.2 Windows NT4.0 For IR use, Windows NT4.0 requires installation of QuickBeam software from Extended Systems (www.extendedsystems.com). Desktop PCs and laptops without built-in IR ports also require adding an IR dongle. While laptops with a built-in IR port normally do not require a dongle, its addition might be necessary in some cases. B.1.0.3 Windows Me/98SE/98/95 The Windows 98SE and Me operating systems include IR drivers.

• Page 209: Ultrasonic Thickness Gauge Theory Of Operation

  Appendix C. Appendix C. Ultrasonic Thickness Gauge Theory of Operation All ultrasonic thickness gauging involves timing the round trip of a sound pulse in a test material. Because solid metal has an acoustic impedance that differs from that of gases, liquids, or corrosion products such as scale or rust, the sound pulse will reflect from the far surface of the remaining metal.

• Page 210
  Appendix C. Transducer Figure 171: Proper Alignment of Transducers for Cylindrical Surfaces While firm hand pressure on the transducer is necessary for good readings, the probe should never be scraped along or twisted against a rough metal surface. This will scratch the face of the transducer and eventually degrade performance.
