In most industrial facilities Compressed Dry Air is a primary component of overall energy use. In fact, compressed air is considered to be the “fourth utility” after electricity, natural gas and water, and its cost is very often higher than the other three when compared by cost per delivered unit of energy. An efficient compressed dry air system effectively balances six basic aspects — total demand, output air quality, operational supply, system storage, on demand distribution, and overall management. All six elements must work together for the system to reach its maximum efficiency. As the costs of energy continues to rise, accurately tracking the use of compressed air with our thermal mass flow meters can provide direct and immediate benefits by giving you the information you need to establish a program that:
monitors general usage to encourage energy and plant cost conservation;
tracks peak usage to correctly determine optimum compressor capacity; and
simplifies your overall gas measurement instrumentation needs through the use of thermal gas mass flow technology.
Determining the true demand in a compressed air system, whether for a new installation or for an upgrade, can be a difficult task but it is critical first step in any design. Once operational, the demands upon a system will typically fluctuate significantly. In either case, the most accurate method of monitoring the system is through the use of one or more flow meters installed at strategic locations in the facility served by the system.
