This system offers a wide variety of output modes and functions, allowing it to operate similarly to a pressure sensor. In addition, the two-color indicator enables quick, at-a-glance confirmation of workpiece suction, improving visibility during operation. Moreover, users can configure flow rate settings, import flow rate values, and set reference flow rates directly on a computer. As a result, setup becomes easier, control becomes more precise, and overall system management becomes more efficient.
