The 490W Series Liquid Differential Pressure Measurement Kit is currently the most convenient and accurate differential pressure measurement device on the market that can be operated via a mobile phone. It uses wireless sensors paired with mobile devices for monitoring, allowing one person to perform comprehensive monitoring and recording to balance hydraulic systems. Compared to traditional hydraulic balancing instruments, it can save a lot of time. The 490W Series wireless sensors can be used with Dwyer's UHH6 handheld device or with your own phone to monitor and record differential pressure or flow. Using mobile communication technology, it communicates with the sensors via Bluetooth to monitor pressure differences and flow. There's no need to use measurement tubes to connect instruments, nor to install relief valves. Paired with the 490W is Dwyer's hydraulic application software app, which includes many valve characteristic parameters from various valve manufacturers, allowing you to convert differential pressure into flow and display it directly on the screen.
