Influx FloTrak metal VA flowmeter
23 September, 2011 byThe Influx FloTrak metal VA flowmeter is designed for the measurement of gas and liquid. Fluid passing through an orifice within the tube causes a profiled float to assume a position where the forces created by flow are balanced by the weight of the float. A magnet in the float is sensed by the FloTrak system, providing a direct reading flow rate scale, optional alarms or a 4-20 mA output.
McCrometer V-Cone DP flow meter
21 September, 2011McCrometer’s V-Cone flow meter is claimed to be inherently more accurate than traditional DP instruments because of the flow conditioning function built into its sensor design. Its centrally located cone interacts with the fluid steam, reshaping the velocity profile to provide a stable signal that increases measurement accuracy.
Endress+Hauser Promass 83X/84X four-tube Coriolis mass flow meter
21 July, 2011 byThe Promass 83X/84X is claimed to be the world’s first large, four-tube Coriolis mass flow meter. The 14″ (DN350) diameter flowmeter is suitable for measuring the mass flow, density and temperature of oil, gas and other fluids in large pipes, at flow rates up to 4100 tonnes/h.
Endress+Hauser EngyCal RH33 Btu and RS33 steam billing meters
14 July, 2011 byThe EngyCal RH33 Btu meter and RS33 steam meter provide high-precision data recording and billing information for custody transfer, steam measurement and energy-flow calculations for process and facility applications.
Trimec TM Turbopulse/TP Turbopulse turbine meter series
22 June, 2011 byThe Trimec TM Turbopulse mini and the larger TP Turbopulse turbine meter series measure flows of low viscosity liquids from 3 to 7,000,000 L/h in a range of sizes from 1/4 to 20″ (6~500 mm).
Dwyer Series ULF ultrasonic flow measurement transmitter
02 June, 2011 byThe Series ULF is an ultrasonic continuous flow measurement transmitter suitable for maintenance-free, non-contact measurement of open channels. This series operates on ultrasonic technology and is claimed to offer dependable, highly accurate measurements.
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.
