  • Balancing A Variable Flow Water System Will Ruin the Control System
    Many seminars and technical sessions have been held to outline procedures for balancing variable flow water systems. Most of these sessions recommend "Proportional Balance." When this technique is used, all control valves are set wide open and the circulating pump is operated at maximum speed
  • Methods of Modulating Air Flow
    : Increase pressure, using louvers to block air flow. Reduce blade angle, using automatic fans and single speed motors. Reduce RPM, using variable-speed motors. All three, when provided with suitable sensing and control devices, can provide a fine degree of control as ambient conditions change
  • Understanding Capillary Tube Thermal Mass Flow Meters & Controllers:
    Mass Flow Meter or Controller?. Capillary tube thermal mass flow meters directly measure the mass flow rate of clean gases and gas mixtures in lower flow ranges. A capillary tube thermal mass flow controller adds an integrally mounted flow control valve to the flow body of the mass flow meter
  • Part 2-Flow Energy Management Applications-Installation Tips & Tricks
    devices allow users to easily and quickly program the menu, including instantaneous flow rate, positive total, negative total, net total, velocity, date and time, and daily flow results. Wireless Bluetooth-enabled android tablet PC devices make it even easier to control data acquisition
  • Video: Select The Right Mass Flow Controller For Your Application
    your application via computer with totalization, batch control, input control, mixing gases, blending gas, and setting alarms. See how SmartTrak 100 was instrumental in a suspended animation experiment by Dr. Kraus, allowing him to achieve his research goals with precise gas flow. When you expect
  • Thermal Mass Flow Meter Supports Feedback Control Loop In Boiler System for Thermal Electric Power Generation
    To meet China's growing need for electric power. generation, the Guohua Ninghai Power Plant has a total planned operating capacity of 4 x 600 MW [Phase 1]. The plant is located south of Shanghai in Ninghai township, Ningbo city, Zhejiang
  • Worcester Controls Corp. Eliminates Galling and Boosts Ball Valve Life 50% With Mirror-Smooth Coating
    For more than four decades, Worcester Controls Corporation has been on the leading edge of ball valve and flow control technology. The Marlborough (Mass.) company has always prided itself on making and selling state-of-the-art products of the highest quality. So Worcester was seriously concerned
  • Natural Gas in Venezuela: Flowmeter Applications
    Hoffer Flow Controls has recently supplied two computerized natural gas turbine flow measuring systems to Venezuela's gas industry. These systems accurately measure "mass" flow rate and total. Venezuela has enormous gas resources and measuring it accurately is critical because of its value. In one
