SERIES 490W | WIRELESS HYDRONIC DIFFERENTIAL PRESSURE MANOMETER

Optional handheld

device UHH7

shown

BENEFITS/FEATURES

• Rugged weatherproof handheld housing withstands 1.0 meter drop test

• Wireless measurement of differential pressure, single pressure and air ow

• Ergonomic design is much lighter and easier to work with, providing greater maneuverability and quick install setup

DESCRIPTIONAPPLICATIONS

• Refrigerant pressure testing

• Hydronic valve balancing

• Measure pressure drop across pumps

• Measure pressure drop across chiller and coils for freeze protection

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 ow 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 ow directly on the screen.
