-Robert Roda, Danbury, CT When it comes to choosing a flow meter engineers are spoiled with choices, making selection of the appropriate meter a daunting task simply due to the sheer number of possible types of measurement devices: differential-pressure, thermal mass, turbine, and vortex meters being among the most common. Vortex meters, however, offer some unique advantages and […]
Draft Controls Are Still a Critical Part of Modern Boiler Operation
New updates to our draft controllers, including the popular JC-22 model, make it an even more effective solution. Draft controls have long been an important component in boiler systems to help control negative pressure. Even though modern forced draft boilers are usually airtight, they still often need draft controls to help stabilize burners using flue gas recirculation for […]
