Abstract

The research aims to increase the accuracy of gas metering in conditions unfavorable to the flow conditioner, with a focus on acoustic noise reduction in a wide frequency range. The study explores how the proposed modified design of cylindrical flow conditioners with stainless steel and rubber fillers affects noise reduction, including the signal-to-noise ratio of ultrasonic flow meters' sensors, straightening of velocity profiles in pipelines, and drag. Compared to the design without fillers, the latter reduce the noise in the frequency range of 5–115 kHz up to 3.7 times, increase the signal-to-noise ratio of ultrasonic flow conditioners’ sensors up to 2 times, and can improve the conditioning of velocity profiles. At the same time, the pressure loss in the device is three times lower, on average, compared to a number of mass-produced flow conditioners.

采用橡胶和钢填料的气体计量圆柱形流量调节器的声学和流体动力性能增强

该研究旨在提高对流量调节器不利的条件下气体计量的准确性，重点是在宽频率范围内降低噪声。该研究探讨了采用不锈钢和橡胶填料的圆柱形调节阀的改进设计如何影响降噪，包括超声波流量计传感器的信噪比、管道速度曲线的矫直以及阻力。与不加填料的设计相比，填料可使5-115 kHz频率范围内的噪声降低3.7倍，使超声波流量调节器传感器的信噪比提高2倍，并可改善速度剖面的调节。同时，与大量生产的流量调节器相比，该装置的压力损失平均降低了三倍。

期刊介绍： Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions. FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest: Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible. Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems. Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories. Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
