FCI ST100 Series thermal mass flow meter
01 June, 2011The ST100 Series thermal mass flow meter from Fluid Components International (FCI) now provides a modular design so that the flow meter can be adapted as necessary with a plug-in card replacement that can be changed out by plant technicians in the field. The meter can provide conventional 4-20 mA analog, frequency/pulse, alarm relays or digital bus communications such as HART, Foundation Fieldbus, Profibus or Modbus.
Gems FS-600 Series flow switch
17 May, 2011 byThe Gems FS-600 Series flow switch has a robust, ‘no moving parts’ design that works with both conductive and non-conductive fluids.
Hydac HFS 2500 flow switch for water-based media
17 May, 2011 byThe HFS 2500 flow switch is based on the variable area float principle and can be used in any position in the system. The test medium moves a spring-loaded float in the direction of flow, depending on the flow rate. A reed contact is fitted to the outside and is therefore separate from the flow circuit. When the magnet inside the float reaches the preset position, the reed contact will switch.
Trimec Multipulse Oval series PD flowmeters
13 May, 2011 byThe Trimec Multipulse Oval series PD flowmeters offer a high level of accuracy, turndown and repeatability. These precision meters are used for flow-rate measurement in flow monitoring and control applications and for totalising in dispensing and batching.
Vortex shedding tutorial - Part 3
21 April, 2011 by Wade Mattar and James Vignos, PhD, Foxboro, InvensysIn Parts 1 and 2 of this article on vortex shedding flowmeters we looked in detail at how they work and how they are constructed. In Part 3 we look at what needs to be considered in the application of vortex flowmeters.
Vortex shedding tutorial - Part 2
07 April, 2011In Part 1 of this article on vortex shedding flowmeters we looked at the principles of their operation and the basic construction of the meter. In Part 2 we examine the transducer and the transmitter.
Eastern Instruments CentriFlow solids flowmeter
23 March, 2011 byThe CentriFlow solids flowmeter from Eastern Instruments is designed to replace weigh belts, impact meters, loss-in-weight meters and static weigh scales, where accuracy, low maintenance and zero drift are paramount.
Vortex shedding tutorial - Part 1
03 March, 2011The vortex shedding flowmeter first emerged 25 to 30 years ago and has steadily grown in acceptance, since then, to be a major flow measurement technique. Its appeal is due, in part, to the fact that it has no moving parts yet produces a frequency output that varies linearly with flowrate over a wide range of Reynolds numbers.
Flowmeters help recover lost revenues and promote energy efficiency
25 February, 2011Virginia Commonwealth University (VCU) in Richmond, Virginia, operates a steam plant for its huge downtown campus, generating steam for almost 60 buildings, including three hospitals, the governor’s mansion and a museum. Three identical boilers produce around 163,000 tonnes of steam a year.
weber Sensors mini vent-captor type 3505/3022.30 airflow meter
29 October, 2010 byThe weber Sensors mini vent-captor type 3505/3022.30 is a remote airflow meter for industrial applications, suitable for small pipe sizes from ID 10 to 15 mm.
Siemens Sitrans FST020 clamp-on ultrasonic flowmeter
14 October, 2010 byThe Sitrans FST020 clamp-on ultrasonic flowmeter is designed specifically for basic applications that only require flow reading functionality along with easy communication capabilities. The device measures almost any liquid and meets the specific requirements of industries such as water and wastewater, HVAC, power and chemical. The flowmeter can be installed on pipes up to DN 9000 (9000 mm) in size and, because of the simplified configuration options and set-up, can be quickly commissioned.
Dwyer Series AVFS adjustable air flow switch
17 September, 2010 byThe Series AVFS adjustable air flow switch is specifically designed to monitor air flow in ducts and provides a 3A contact output to indicate a change or loss of flow. The AVFS will signal a loss of flow and the normally open SPST output will indicate the detected decrease. For ease of installation and system troubleshooting, the switch possesses a red/green LED indication to provide local status if the air flow is above (green) or below (red) the set point.
