Bulletin TE-490W-QS
Series 490W 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 flow 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 Dwyer’s Hydronic Application Software that contains valve charts for
numerous manufacturers, which converts differential pressure to flow directly on the
screen.
