This product is suitable for measuring micro flow rates!
The "HV-401" is an optimal hydrogen bubble generator for measuring micro flow rates and unsteady flows, as well as for visualizing flow velocity distributions, streamlines, and flow paths. The state of the water flow (such as streamlines, flow paths, and flow traces) can be visualized, and measurements of turbulence and unsteady flows can also be conducted. Additionally, the output power supply can be selected between pulse mode and direct current mode, resulting in less disturbance of the streamlines at measurement points compared to other measuring instruments. Furthermore, the output utilizes the power supply frequency, making the pulse period very accurate. 【Features】 ■ Minimal disturbance of streamlines ■ Accurate output pulse intervals ■ Capable of measuring micro flow rates ■ Synchronization with external signals is possible *For more details, please refer to the catalog or feel free to contact us.
