Dwyer’s Series 490W Wireless Hydronic Differential Pressure Manometer is the most accurate and easy-to-operate manometer on the market. Along with wireless transducers and a mobile device, a single operator using a 490W can monitor and balance a hydronic system in less time and with less manpower than would be possible using a traditional hydronic balancer. In addition, being wireless, the 490W has zero hoses or manifolds – meaning there are no annoying attachments that need to be carried, that can snag onto equipment, or that need to be drained between readings.

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”
