Flow Measurement and Instrumentation

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.
Multiphase behaviour: whether purpose-designed, or adapted from single-phase operation, coverage of systems for single-phase liquid and gas flows, multiphase flows having solid, liquid and gas phases, and slurries and pastes is equally welcome.
Associated measurements and secondary instrumentation: for example, density, viscosity and secondary instrumentation effects.

All contributions are subject to peer review, and additional features include:

Case studies

Flow Measurement and Instrumentation is essential reading for instrumentation engineers in the oil, gas, power, chemical, food, water and waste treatment industries, manufacturers of flowmeters, and academics involved in research in this area.

Twin-wire resistance probe rotameter

The principle of the twin-wire resistance probe rotameter is developed in this article. The main feature of the design is a low-cost flowmeter with an electrical output capability. From performance tests conducted on both a simulated rotameter and an actual rotameter constructed based on the principle described, good agreement was observed between experimental and analytical results. It was found that the output voltage from this flowmeter depends mainly upon the material and the size of the float used, and the angle of the taper of the surface of the meter.
Note: Ultrasonic gas flowmeter based on optimized time-of-flight algorithms.

A new digital signal processor based single path ultrasonic gas flowmeter is designed, constructed, and experimentally tested. To achieve high accuracy measurements, an optimized ultrasound driven method of incorporation of the amplitude modulation and the phase modulation of the transmit-receive technique is used to stimulate the transmitter. Based on the regularities among the received envelope zero-crossings, different received signal's signal-to-noise ratio situations are discriminated and optional time-of-flight algorithms are applied to take flow rate calculations. Experimental results from the dry calibration indicate that the designed flowmeter prototype can meet the zero-flow verification test requirements of the American Gas Association.
Curved-tube flowmeters
new flowmeter design is presented which is suitable for accurately measuring flows ranging from [bar_over_tilde:_approx._equal_to]1 to [bar_over_tilde:_approx._equal_to]1000 cm3 s-1. It may be simply constructed from readily available parts and may be adapted to measure flow of any fluid for which a noncorrosive ball and transparent tube are available. Starting with standard Venturi meter theory, a formula is derived for the volume flowrate in terms of ball and tube dimensions, ball and fluid densities, and the angle at which the ball comes to rest in the tube. Actual examples of curved-tube flowmeters are given for particular cases of nitrogen at 0 – 42.4 cm3 s-1 and water at 0–11.4 cm3 s-1, constructed using bearing balls in standard Eastman Polyflo tubing. Using the formula as a guide, extension to lower and higher flowrates is straightforward.
Note: Anti-strong-disturbance signal processing method of vortex flowmeter with two sensors.

Some digital signal processing methods have been used to deal with the output signal of vortex flowmeter for extracting the flow rate frequency from the noisy output of vortex flow rate sensor and achieving the measurement of small flow rate. In applications, however, the power of noise is larger than that of flow rate sometimes. These strong disturbances are caused by pipe vibration mostly. Under this condition the previous digital signal processing methods will be unavailable. Therefore, an anti-strong-disturbance solution is studied for the vortex flowmeter with two sensors in this Note.
Optimal Control of the Valve Based on Traveling Wave Method in the Water Hammer Process.
AIP Conference Proceedings; 9/28/2011, Vol. 1376 Issue 1, p436-440, 5p

Valve regulation is an effective method for process control during the water hammer. The principle of d'Alembert traveling wave theory was used in this paper to construct the exact analytical solution of the water hammer, and the optimal speed law of the valve that can reduce the water hammer pressure in the maximum extent was obtained. Combining this law with the valve characteristic curve, the principle corresponding to the valve opening changing with time was obtained, which can be used to guide the process of valve closing and to reduce the water hammer pressure in the maximum extent.
