Question: I need to decide on a flow meter for my application. I see that your Rate-Master® Polycarbonate Flowmeter, Series RM, and Visi-Float® Acrylic Flowmeter, Series VF, are the most popular series; how should I decide which would be best for my application? Continue reading “Ask the Expert: How should I decide which flow meter would be best for my application?”
In 2018, Dwyer released two globally recognized products to meet the demands of our customers in the HVAC industry: the Wireless Hydronic Balancing Kit and Insertion Electromagnetic Flow Transmitter. For the upcoming 2019 AHR trade fair in Atlanta, Georgia, the Dwyer team raised the bar another level with a slew of new product innovations that will debut at booth 5407.
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.”
Last September, we wrote about the different types of pressure and how each type is referenced. This post discussed atmospheric (barometric), absolute, gage, vacuum, differential, and hydrostatic pressure. For a refresher on these pressure types, click here. This post will expand on last September’s post by listing some more key pressure measurements and explaining their importance. Continue reading “Select Key Pressure Measurements and Their Importance”
