The Y-Flow product family consists of the Y-Flow YFFC (field flow computer; photo) and Y-Flow YRTU (remote terminal unit). The Y-Flow YFFC is a low-power, orifice-flow computer designed to measure AGA 3 orifice gas flow and the Y-Flow YRTU is a low-power remote terminal unit designed to measure various complex AGA gas flow calculations, as well as remote control applications. The Y-Flow YFFC utilizes the company’s EJX910A multivariable transmitter capsule and communication board. The multivariable capsule and communication board are integrated into the flow computer as a single unit, thus reducing the cost of ownership and providing an accurate and precise measurement. The Y-Flow YRTU is a remote terminal unit that allows an external turbine meter, ultrasonic meter, multivariable transmitters and Coriolis meter to be connected to measure complex AGA gas flow calculations. — Yokogawa Corp. of America, Newnan, Ga.
