Yokogawa Corporation of America announced the release of Y-Flow. The Y-Flow product family consists of the Y-Flow YFFC (Field Flow Computer) and Y-Flow YRTU (Remote Terminal Unit). The Y-Flow YFFC is a computer designed to measure AGA 3 orifice gas flow and the Y-Flow YRTU is a remote terminal unit designed to measure various complex AGA gas flow calculations as well as remote control applications.

The overall basic function of an electronic flow computer is to calculate and record flow rate using industry standard algorithms as natural gas and other hydrocarbons pass through a meter of a segmented section of pipeline. These meters could include, but are not limited to, orifice meters, linear meters, ultrasonic meters, or Coriolis meters.

A typical orifice measurement application requires a differential pressure transmitter, static pressure transducer and temperature probe. Many flow computers use a multivariable transmitter that can measure differential pressure and static pressure in one transmitter.

The Y-Flow YFFC is a co-innovation development between Eagle Research Corporation and Yokogawa. The Y-Flow YFFC utilizes Yokogawa’s EJX910A multivariable transmitter capsule and communication board. The EJX910A uses the established DPharp pressure sensor technology that allows for simultaneous measurement of differential pressure and static pressure (absolute or gauge) from one sensor. The multivariable capsule and communication board are integrated into the flow computer as a single unit..

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. In addition, the Y-Flow YRTU can measure, monitor and control other remote applications.
