This paper is the final report of an evaluation and research project on the metrological performances of six different mass flowmeters of the Coriolis type which were extensively tested, under identical operating conditions, at the IMGC flow measurement laboratory, making use of the Italian national standard calibration facilities. The first results of the evaluation project, already detailed in a previous paper, are also briefly reviewed.evaluate the metrological characteristics of several commercially-available CMFs. The main aims of this investigation are: 8B making a comparative evaluation of as many CMFs of different design as possible, by testing them at an independent laboratory in identical conditions of practical interest to users; improving the knowledge of the metrological characteristics exhibited by a representative sample of CMFs, in order to allow a basic assessment of the performances of the whole class of such instruments.The test programme and the first results of this research were reported in Cascetta et al (1992) and are here briefly recalled. Further, this paper presents the results of the second part of the project, which consisted of on the influence of fluid density and fluid temperature. The extensive set of data given in both papers, which summarise many thousands of measurements, provides a further contribution to the documented characteristics of this type of flowmeter. The metrological evaluation programmeThe tests, as agreed with each manufacturer, include calibration of each meter:~ in water, by varying pressure (up to 400 kPa) and temperature (up to +80°C); in a test fluid (MIL-C-7042-B type II) in substitution for JP4 kerosene (in the following text called simply 'JP4 k~rc~sene'), whose density and viscosity at 20°C are respectively 768.5 kg/m3 and 1.~'l mm2/s; in a two-phase fluid, namely water mixed with a small amount (up to 10% in volume) of air bubbles. It must be stressed that this experimental evaluation was performed on a single instrument for each manufacturer. Therefore, the test results do not provide justification for a quality judgement on other flowmeters, and even less to a whole product line of instrumentation. It should also be noted that, by now, many improvements have been incorporated in most CMFs available today, owing to the fast development of this comparitively young technology.The model that each company was asked to provide was chosen in view of comparing meters with similar measurement flow ranges: more precisely, with full scale (FS) values as close as possible to each other.These FS values, for use in water at room temperature and low line pressure, ranged between 2.8 kg/s and 4.5 kg/s. All the CMFs chosen are equipped with DN 25 flanges.All flowmeters but one were tested by measuring their DC output across a standard resistor: this choice, according to previous experiences at the IMGC flow laboratory, is thought to be fully adequate and more reliable with respect to electromagnetic noise (Wade and Dandridge, 1988). Just one flowmeter, instead, was t...

“…However, this effect has been recognized by the industry and has been compensated for by using an internal temperature sensor and automatically adjusting the calibration for temperature. By the early 1990s, most of these types of flow meters on the market included temperature compensation (Cascetta et al, 1992).…”

“…The Coriolis mass flowmeter (CMF) is a high-precision device utilized to measure the mass flow of fluid directly and has wide application in many industries, such as the petrochemical industry, food processing industry, etc. (Cascetta et al, 1992; Haneveld et al, 2010; Ma and Eidenschink, 2001; Zheng et al, 2009).…”

In this paper, the normalized least mean square (NLMS) algorithm, a time-varying signal processing method, is employed in a Coriolis mass flowmeter (CFM) to improve its weak anti-jamming capability. Initially, the fundamental principles of the NLMS algorithm adopted in the adaptive filter are analysed. Then, the NLMS algorithm is applied to analyse the signal processing of the CFM at different flow rates in experiments. By comparing several performance indicators and spectrum diagrams from being filtered by the NLMS algorithm and the least mean square (LMS) algorithm, the results indicate that the NLMS algorithm can lead to a better anti-jamming capability and reduce the influence of noise efficiently for the CFM. In addition, the NLMS method has a faster convergence speed and fewer stable errors than the LMS method. Therefore, the NLMS can improve the quality of the output signal of the CFM.
