Methods of measurement

Flow measurement is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. The common types of flowmeters with industrial applications are listed below:

• a) Obstruction type (differential pressure or variable area)
• b) Inferential (turbine type)
• c) Electromagnetic
• d) Positive-displacement flowmeters, which accumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow.
• e) Fluid dynamic (vortex shedding)
• f) Anemometer
• g) Ultrasonic
• h) Mass flowmeter (Coriolis force).

Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area. For very large flows, tracer methods may be used to deduce the flow rate from the change in concentration of a dye or radioisotope.

My experience in flow measurement systems:

• Build a R&D team, how developed or improve most part of flowmeters type electronics
• Delivered to mass production a prototype of a vortex flowmeter. To date, more than 70,000 devices have been produced.
• Provided studies of the influence of the shape of the bluff body on the process of vortex formation. Participated in the development of signal processing algorithms using FFT and digital filtering based on ADSP, wrote the code.
• Made research of magnetic systems for Coriolis flowmeter.
• Participated in the development of mechanics, magnetic system and production technology of the instrument case. Participated in the development of signal processing algorithms for the electronics of the Coriolis flowmeter. Developed some modules for electronics.
• Participated in the construction of the mat model and conducted simulations, as well as tests of the 8-beam ultrasonic flowmeter. He also formed algorithms for correcting flow from pressure and their subsequent implementation in the code for ADSP.
• Participated in the development of mechanics, sensor sealing systems. Participated in the development of electronic modules.
• Provided logistics of electronic components for the production of developed modules in 3 regions (Europe, Asia, Russia).
• Audited more than 40 sub-contract electronic factories.
• Provided uninterrupted contract manufacturing of electronic modules with international logistic.
• Provided input control of modules, as well as technological processes of assembly, firmware, adjustment, adjustment, verification of devices.
• Provided certification of metrological support, as well as other standards, such as ATEX.
• Partially implemented ERP system on the factory.
• Implemented HART protocol in some devices.
• Organized a new direction, including a business plan, technical solution, staffing, business processes - light.
