490W Wireless Hydronic Differential Pressure Manometer
The most accurate and easy to operate manometer on the market
The Series 490W Wireless Hydronic Differential Pressure Manometer is the most accurate and easy to operate manometer on the market. By using wireless transducers and a mobile device, a single operator can monitor and balance a hydronic system in less time than traditional hydronic balancers. The Series 490W transducers connect wirelessly to a UHH6 or newer handheld device, or your own mobile device, to monitor differential pressure and flow on up to three different valves. Being wireless, there are no hoses to carry, snag on equipment or needing to be drained. The 490W utilizes Dwyer’s hydronic application software that contains valve charts for numerous manufacturers, which converts differential pressure to flow directly on the screen.
