Air balancing is the process of testing and adjusting an HVAC system to deliver the correct amount of air to each room of a building. The most common tool used in air balancing is an air flow hood, which measures the volume of air coming out of a diffuser in order to find areas of the system where the flow is limited. The 2016 Dealer Design Award-winning SMART Air Hood® Balancing Instrument, Series SAH, was designed by your HVAC market leader to be the most accurate and easy to operate air flow hood on the market. But what exactly gives the Series SAH an advantage against comparable products? Continue reading “8 Reasons to Buy the SMART Air Hood® Balancing Instrument”
I often get asked, how should one simplify the hydronic balancing process? Since system blueprints will specify exactly where to set the balancing valves on the hydronic system to achieve proportional flow, it may seem simple enough for an installing contractor to determine the pressure drop through each circuit; however, hydronic systems are rarely installed exactly as designed. Continue reading “Work Smarter, Not Harder. Hydronic Balancing Simplified.”
Tune in to watch Dwyer Instruments, Inc. on Inside the Blueprint TV show. Airing on Fox Business Network on Sunday, October 28th at 2:30pm (CST), the show will introduce the SMART Air Hood® Balancing Instrument and the ways in which this innovative product improves the process of balancing HVAC systems.
Insertion flowmeters provide a great alternative to inline flowmeters because they are typically less expensive and easier to install than inline meters. But how do you know which type of insertion meter to choose?
There are two primary types of insertion flowmeters: mechanical and non-mechanical. It’s vital to understand the application and benefits of each type of meter, to ensure the best instrumentation solution for your application. Continue reading “Mechanical vs. Non-Mechanical Flowmeters”
It is the first day on the job for a new contractor. Their project is to balance the HVAC system of a commercial office space. The contractor measures the total pressure and static pressure in the office duct work, using an air velocity manometer, and then calculates the velocity. The velocity measurement seems high, so the contractor is led to believe that either the measuring instrument isn’t precise enough, or the calculations are off. Therefore, the contractor turns to a duct traverse to check the velocity measurement. Continue reading “Duct Traverse Process with Modern Technology”
