Bernoulli basics
This 13-minute video, āUnderstanding Bernoulliās equation,ā covers the equation itself, conservation of energy, the continuity equation, Bernoulliās principle, pitostatic tubing, Venturi meters and limitations.
Give me steam
This whitepaper, āImprove efficiency and effectiveness when measuring steam flow in process industries,ā coversadvanced differential pressure (DP) flow and vortex technologies that let users know where steam is being used and how to optimize it to improve operations and decrease costs. It also shows how selecting the right steam flow measurement eliminates leak points, compensates for changing fluid density, integrates temperature sensors, decreases maintenance, and reduces flow error. Itās downloadable with a brief signup here.
Flow fundamentals
This 10-minute video, āAn overview of flowmeter technologies,ā covers fundamental technologies, such as variable area, mechanical, electromechanical, DP elements, electromechanical, oval gear, positive displacement, vortex shutters, transit time and Doppler flowmeters.
Mass, laminar and turbulent
The first of two blog posts, āWhat is a mass flow controller?,ā includes typical applications, workingĀ principles and types, and compares mass flow and volume flow technologies. It also features two short videos on thermal and Coroilis mass flow controllers. Itās here. The second blog post, āWhatās the difference between laminar flow and turbulent flow?ā by Allard Overmeen, includes his three tips for minimizes the disadvantageous effects of turbulent flows. Itās here.
Magnetic and ultrasonic videosĀ
This 10-minute video, āMagnetic flowmeter explainedā covers magnetic flow sensors, Faradayās Law, conductive fluids and installation considerations.
A second video, āUltrasonic flowmeters explained,ā covers their physical, mechanical and electrical principles, as well as dynamics, design considerations and applications.
Turbine flow sensor and PLC vs. rotameterĀ
This online paper, āFlow rate control by means of a flowmeter and PLCā edited by Alessandro Bevilaqua, presents an interesting design for flowmeter controlled by a PLC, Gems FT-210 turbine flow sensor, and APB software, including a comparison of its performance with Krohne VA-40 rotameter. Itās here.
Four types for oil and gas
This five-minute video, āLiquid and gas measurement: four types of flowmeters for oil and gas,ā covers mass, Coriolis, thermal mass, turbine, vortex, ultrasonic, DP and positive displacement, and shows how they can be used in both upstream production and midstream transportation. In upstream production, they can be used to monitor individual well production, custody transfer at a sales meter or to meter the amount of chemicals being injected. In the midstream, they can be used for inventory measurement, process control, fuel management and regulatory reporting.
Types, unitsāand history
This online article, āTechnical & practical flowmeter handbook,ā covers types, technologies, measurement units, flowmeter selection criteria, calibration, and even traces major events in the history of flow measurement. Itās here.
Six videos and gas calculations
This blog post, āSix best flow measurement techniques used in industries,ā provides basic definitions and formulas; links to six of Endress+Hauserās videos on differential pressure, thermal, vortex, electromagnetic, ultrasonic and Coriolis flowmeters; and demonstrates PLC programming to calculate gas flows. It's here.
Calibrate and certifyĀ
This seven-minute video, āCalibration, certification and recertification of Coriolis flowmeters,ā reports on calibrating by using its gravametic comparison to a mass total, and its transfer standard method using a master meter thatās been checked and certified.
Essentials and answers
This online article, āMastering the basics of flow controlsā by Will Don, marketing director at ThinkTank, introduces all the essential flow control methods and valve technologies, such as globe, ball, check automatic recirculation, diaphragm, pinch and pressure reducing, and answers common questions about selection, maintenance and many others. Itās here.
Do over from last October
This online article, ā11 flow measurement resources you need to seeā by Controlās executive editor Jim Montague, provides documents, videos and other educational resources on flow from Endress+Hauser, Emerson, ABB, Fluke and other suppliers. ItāsĀ here.
