Elimination of bearings, one of the major causes of product failure, while maintaining high-precision fluid measurement capabilities through proprietary technology.

Simple is the best! A flow meter that enables precise fluid measurement within a margin of error of 0.5% even without bearings. Simple structure -> Reduced production costs -> No failures -> Achieving customer satisfaction with reasonable cost performance. It can be used not only for general fluid control devices but also for precision equipment (various facilities related to semiconductors, vehicles, and electronics).
