DESCRIPTIONAPPLICATIONS

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 versatile handheld, a single operator can monitor and balance a hydronic system in less time than traditional hydronic balancers. The Series 490W utilizes mobile technology to communicate via a Bluetooth connection with the transducers to monitor

differential pressure and ow on up to three different valves. Being wireless

means there are no hoses to carry, snag on equipment or needing to be drained. The 490W includes the Dwyer Hydronic Application Software that contains valve charts for numerous manufacturers, which converts

differential pressure to ow directly on the screen.
