Not So Element-ary
New Primary Elements Expand Reach of DP Flowmetering
Differential-pressure (DP) flowmeters rely on what is commonly called a 'primary element' to foster the conditions for flow measurement. Primary elements place a constriction in the flowstream that causes a drop in line pressure. A DP flowmeter uses the pressure differential created between the upstream and downstream pressure to compute the flowrate.

Top Technologies of 2009
Flow Control Innovation Awards Winners
The Flow Control Innovation Awards program is an annual competition designed to recognize the year's most compelling advances in fluid handling technology. Finalists for the 2009 Flow Control Innovation Awards were announced in the June issue of Flow Control magazine, at which time this year's nominees were offered up for open voting. All told, the 2009 Flow Control Innovation Awards program generated 1,300 votes, the most in the 12-year history of the Flow Control Innovation Awards program. Here we provide a brief overview of each of the winning technologies, with select voter comments.

New Products
 
Electromagnetic Flowmeters
Designed for Water & Wastewater Apps
ABB Instrumentation's WaterMaster electromagnetic flowmeters are specifically designed for water and wastewater applications. Part of ABB's new FlowMaster range of flowmeters, the meters are available in flowmeter sizes from 1.5' to 12 inches.

Rotating Vane Thermo-Anemometer
Handheld for Airflow & Temp. Measurement
Omega Engineering's HHF143 thermo-anemometer provides accurate air velocity and temperature measurements in harsh environments.

VFD Cabling
2000 Volt Design for High-Power AC Drives
Belden's 2000 Volt VFD cable designs feature oversized XLPE insulation to provide the lowest capacitance available in a VFD cable. Dual-shielding provides the lowest resistance to ground path, which improves common mode current containment.

Vortex-Shedding Flowmeters
With an Integrated Temperature Transmitter
Universal Flow Monitors' CoolPoint Flow/Temperature Series vortex-shedding flowmeters are designed for measuring and monitoring both flow and temperature in processing water, water with chemicals added, water/glycol coolant and corrosive fluids.

Smart Wireless THUM Adapter
For Existing HART Field Instruments
Emerson Process Management's Smart Wireless THUM Adapter is designed for installation on existing HART field instruments to free up diagnostics and process information that had previously been inaccessible in wired legacy system installations.
