The Yoshitake VDF-100 is a specialized flow measurement series that includes Venturi Flow Meters designed for horizontal pipelines and Orifice Flow Meters designed for vertical pipelines. These meters accommodate line sizes ranging from 50A to 200A with JIS 10K flanged connections and feature wetted parts primarily constructed from stainless steel (SUS304 and SCS13).
