Manufacturing Excellence Since 1931
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.
For anyone who has recently purchased or sold a home, they may have noticed a radon inspection clause in the purchasing agreement. What is radon, and why are we testing for it in our homes?
Radon is an odorless, colorless gas that is naturally released into the environment as a decay byproduct of radium. Radium is a decay byproduct of uranium which can be found in certain types of rock, soil, or water. Some areas have higher concentrations of radon due to the soil composition which leads to additional testing for radon. Continue reading “What is Radon, and Why are We Testing for it in Our Homes?”
Many new users of the award-winning SMART Air Hood® Balancing Instrument (Series SAH) compare their new readings to those of their old, traditional air flow hoods. While the readings on a 3 cone step diffuser, 4 way diffuser and many return registers are very similar; users have noticed that swirl diffusers, slot diffusers and other directional diffusers give a lower reading on the SMART Air Hood® Balancing Instrument when compared to traditional air flow hoods. Continue reading “Why Does the SMART Air Hood® Balancing Instrument Measure a Lower Flow than Traditional Air Flow Hoods?”
The Dwyer SMART Air Hood® Balancing Instrument now has a TABopts Software option to make a great user experience even better.
The software by Ameritech Data Solutions presented with the HVAC air flow hood was unveiled at the 2018 AHR Expo.
How does a revolutionary and multi-award winning HVAC product become even more valuable to customers and the marketplace? Dwyer found a way to provide greater capabilities. Continue reading “TABopts Software for the Award Winning SMART Air Hood® Balancing Instrument”
Dwyer Instruments, Inc. offers a multitude of sensors for monitoring air velocity in HVAC systems. Some of this instrumentation has a simple construction (Pitot tubes, for example) while others are more complex, such as hot-wire anemometers.
The initial term and first “hot-wire anemometer” was developed back in 1914 by Louie Vesso King. He is also accredited for King’s Law, which mathematically describes heat transfer in air flows using a heated wire. As the air moves over the wire, it causes a loss of temperature in the wire and removes some of the wire’s heat energy. Continue reading “Understanding Air Velocity Sensors”
