Flow Control - Jan 2012
4 20 mA control of standard PRV End Result Pressure management is becoming a very popular topic as water utilities are being pushed to maximize the efficiencies of their systems and reduce the water loss and leakage rates There are many different solutions available and a well thought out program utilizing various options can often be the best approach A well thought out pressure management solution can have a very short payback period when reviewing a business plan showing cost of water saved versus capital costs for initial installation The end result is more efficient use of our increasingly scarce supply of water FC Brad Clarke is a vice president with Singer Valve Inc a global designer and manufacturer of automatic control valves He has spent the last 35 years working in the water industry and has written and presented several papers around the world on key issues related to the improving the operation conservation and management of water systems www singervalve com GF40 80 Series Mass Flow Controllers With Brooks patented MultiFlo technology you can reconfigure the mass flow controller for different gases and flow ranges without sacrificing performance or having to remove the device from the gas line Dont try that with a standard MFC Its perfect for applications that call for a variety of gases change gas type frequently or need to re range while preserving measurement and control accuracy Start saving time and money now Download the data sheet at www BrooksInstrument com 60seconds Application Experience Beyond Measure 1 888 554 FLOW www BrooksInstrument com BrooksAM@ BrooksInstrument com Circle 14 or Request Info Instantly at www FlowControlNetwork com 5 Key Strategies for Pressure Management In Water Distribution Systems 1 Standard pressure reducing valves PRVs are a valuable tool as they offer the flexibility to accommodate a variety of functions in the water management system 2 Use time based PRVs with two pressure settings one for daytime and one for nighttime to more efficiently serve peak and offpeak conditions 3 Employ pressure and flow control PRVs where pressures will adjust mechanically based on flow 4 4 20mA control for remote SCADA operation will enable the constant adjusting of pressure based on varying flow 5 Consider pressure relief options to manage surge and transients This will limit the risk of leakage and loss due to pipe bursts or increased stress on the piping system Scan to download the data sheet www FlowControlNetwork com January 2012 21
