SNB10D-425/CU2N

The Yokogawa SNB10D-425/CU2N is a high-performance, flange-mounted vortex flowmeter designed for demanding industrial applications. It is engineered for the highly accurate and reliable volumetric flow measurement of saturated steam, superheated steam, gases, and liquids. A key feature of this model is its all-stainless-steel (SUS316) wetted parts construction, which provides exceptional corrosion resistance, making it ideal for aggressive media or sanitary processes. This specific model is configured for a 4-inch (100 mm) pipeline.
