Page 6: Introduction
INTRODUCTION ……………………………………. Introduction By means of the transit times of ultrasonic pulses, the USZ 08 ultrasonic flowmeter measures the flow velocity of the gas from which it calculates the flow rate at measurement conditions. Here use is made of the fact that ultrasonic pulses move faster in the direction of flow than in the opposite direction.

INTRODUCTION ……………………………………. For non-fiscal metering also the 2-path design of typ USZ 08-2P can be used. This version is equivalent to a reduced 6-path design, which only has the two acoustic paths in the middle plain. Signals are evaluated by the USE 09(-C) ultrasonic electronic system which is installed on the meter case. -

Счетчики газа ультразвуковые модели USZ 08 предназначены для измерений и вычислений объема и объемного расхода природного газа, попутного нефтяного газа, пропана, бутана и других газов при рабочих условиях.
Принцип действия счетчиков основан на методе измерения разности между временем прохождения ультразвуковых импульсов по потоку и против потока газа. Измеренная разность времени, пропорциональна скорости потока, преобразуется в значение объемного расхода.
Ультразвуковой счётчик USZ 08 представляет собой современное измерительное устройство, которое характеризуется высокой надежностью, точностью и стабильностью в работе. Большой измерительный диапазон счетчика позволяет его использовать на газовых станциях с сильно колеблющимся расходом газа.

- крупные промышленные потребители (стекольные, машиностроительные и металлургические заводы);
- и другие объекты нефтегазовой, химической и энергетической отраслей.
- нечувствительность к загрязнениям;
- простое управление;
- независимость от изменений давления;
- электронный метод измерения гарантирует минимальное время реагирования;
- многоступенчатый процесс коррекции обеспечивает максимальную точность;
- двунаправленный принцип работы позволяет использовать оборудование в газовых хранилищах, где заполнение и откачка выполняются по одной и той же нитке;
- чувствительные компоненты отсутствуют, поэтому устройство надёжно защищено от перегрузок;
