SERIES 490W HYDRONIC DIFFERENTIAL PRESSURE MANOMETER

Liquid and Gas Pressure Measurement, 2% of Reading Accuracy

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 the Dwyer® Hydronic Application Software that contains valve charts for numerous manufacturers.

Product Applications

Refrigerant pressure testing
Hydronic valve balancing
Measure pressure drop across pumps
Measure pressure drop across chiller and coils for freeze protection
