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 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 Dwyer’s Hydronic Application Software that contains valve charts for

numerous manufacturers, which converts differential pressure to ow directly on the

screen.

Note: Do not use Murata batteries.

Low Battery Indicator

A weak battery can cause improper operation or inaccurate measurements. The unit
is supplied with a battery that can last up to 2 years, depending on usage. When

transducers are sent in for annual recertication, the battery will be replaced.

Battery life depends on its capacity, operating temperature and
signal transmission interval. When battery replacement becomes
