Mimicking nature for better flow sensors
30 March, 2009Researchers are using the motion-sensing hairs on a blind cavefish as a blueprint for advanced flow sensors.
Passive sonar flowmeter technology — operating principles
18 March, 2009Flow measurements in the mineral processing and mining industry suffer from the limitations placed by previously available flowmeters including the commonly used instruments such as ultrasonic meters, magmeters, turbine meters, orifice plate meters, vortex meters, Coriolis meters and Venturi meters. The desire or requirement to make a non-contact measurement that is accurate and robust, and can be performed on practically any type of fluid within practically any type of pipe, has driven the creation of a new class of flowmeters.
Ultrasonic flow transmitter
12 March, 2009 byThe UTX878 flow ultrasonic transmitter combines the simplicity of a loop-powered meter installation with advanced clamp-on ultrasonic flow transmitter technology.
Thermal mass flowmeter
12 March, 2009 byThe ST75 flowmeter from Fluid Components International is now available in a remote mountable configuration for applications in hazardous areas or hard-to-reach locations. The ST75’s remote mount transmitter, which includes a full digital display, can be mounted up to 15 m away from its thermal mass flow sensor in the process piping and connected via two 0.50" FNPT cables.
Swagelok flowmeters
12 March, 2009Swagelok variable area flowmeters (VAFs) are used to measure liquid and gas flow rates by means of a tapered tube and float, and provide highly accurate measurement with individually calibrated scales and a 10:1 turndown ratio. All Swagelok VAFs are factory calibrated and marked to indicate the specific media, flow range, and accuracy class. In addition, the product can be calibrated and marked to customer-specific applications.
WaterMaster flowmeters
11 March, 2009The WaterMaster range of flowmeters is specifically designed for water, wastewater and sewage applications, and is available in the most commonly installed flowmeter sizes: 40-300 mm.
Digital valve controller wins China's 'best product' award
21 January, 2009Emerson Process Management’s Fisher Fieldvue DVC2000 digital valve controller was named Best Product of the Year 2008 by readers of Control Engineering China Magazine, beating 101 products from 62 countries for the prize.
Scientists create self-powered fluid sensors
04 November, 2008Fraunhofer researchers have created a fluidic energy transducer that creates electricity from fluid motion in the surrounding air or water, enabling the development of self-powered sensors for air or fluid systems.
Bulk solid flow measurement
01 November, 2008SolidFlow can be used to measure lean phase mass flow of bulk solids up to 20 t/h, either in free fall or pneumatically conveyed. It uses a microwave technique.
Printing liquid totaliser
01 November, 2008The ITP is an intelligent printing totaliser intended primarily for liquid flow measurement.
One-stop DP flowmeter solution
01 November, 2008Although differential pressure (DP) flowmeters are based on a relatively inexpensive and mature technology, selecting and installing these devices is not simple and requires a reasonable level of engineering skill.
Flow sensor for solids
05 October, 2008FlowJam is a non-contact flow/no flow sensor for solids. It uses microwave technology to give reliable results under harsh conditions of dust and sunlight. It is a suitable device for detecting solid flows in hoppers, conveyors, screw conveyors, air slides, etc.
Air and gas flowmeters
05 October, 2008The PFM range of flowmeters is for use with air and a variety of gases. With flow measurement of air, liquids, even harsh acids and alkalis, the SMC range of flow measurement equipment can provide in situ displays, remote indicators, analog transmission and digital switching. Some models are equipped with flow adjustment to permit the required flowrate to be preset.
Hygienic flowmeters
05 October, 2008The HygienicMaster range of flowmeters is targeted primarily at the food and beverage, pharmaceutical and biotechnology industries. The range provides accurate measurement in hygienic applications ranging from water through to fluids with extreme viscosities, high solid concentrations or low conductivity.
Variable area flowmeters
05 October, 2008Swagelok variable area flowmeters (VAFs) are used to measure liquid and gas flow rates by means of a tapered tube and float and can provide highly accurate measurement with individually calibrated scales and a 10:1 turndown ratio.
