Earlier this year, Dwyer Instruments released its new look and updated features for the wireless hydronic differential pressure manometer, Series 490W. This product is used for applications including: refrigerant pressure testing, hydronic valve balancing, measuring pressure drop across pumps, and measuring pressure drop across chiller and coils for freeze protection.
The original Series 490W hydronic balancing kit was recognized in 2018 at the AHR Expo Innovation Awards as the winner of the Tools and Instruments product category. Prior to this win, the 490W was also recognized as a Silver Award Winner in the Electronic and Hand Tools product category of the Dealer Design Awards Program sponsored by The Air Conditioning Heating & Refrigeration News magazine (ACHR News).

Radon is a naturally occurring radioactive gas that comes from the decay of Uranium. It is often found in the rock and soil upon which many residential and commercial buildings are built. 
Dwyer Instruments, Inc. was recognized for excellence in product design in the 16th annual Dealer Design Awards Program sponsored by The Air Conditioning Heating & Refrigeration News Magazine (The ACHR News). An independent panel of contractors acted as judges in the contest that had 79 entries. The company’s Hydronic Application Software was the Silver Award Winner in the Contractor Services & Software product category. The ACHR News is the leading trade magazine in the heating, ventilating, air conditioning, and refrigeration industries. 
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.
