Yokogawa Corporation of America is pleased to announce 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 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.
Development Background
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 to reduce cost.
The Y-Flow™ YFFC is a co-innovation development between Eagle Research Corporation and Yokogawa. The Y-Flow® YFFC utilizes Yokogawa’s highly accurate and reliable 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, thus reducing the cost of ownership and providing an accurate and precise measurement.
Y-Flow®YRTU是一个远程终端单元，可以连接外部涡轮计，超声仪，多变量发射器和科里奥利仪表，以测量复杂的AGA气流流量计算。此外，Y-Flow®YRTU可以测量，监视和控制其他远程应用程序。
Product Features
1.同时运行
The Y-Flow® allows for up to two simultaneous flow runs on a single unit. This significantly reduces the cost of ownership and enhances the flexibility of the flow computer. Additionally, the Y-Flow® YFFC features bi-directional index that can measure gas flow in both directions.
2. Low power
由于其低功耗，Y-Flow®可以与太阳能电池板充电器集成，该充电器可支撑高达20瓦。此外，它最多接受32AH太阳能电池板电池。这允许将Y-Flow®安装在不容易获得电源的偏远位置。
3.灵活的通信
Y-FLOW®在RS232/RS485，以太网和USB连接以及Modbus TCP/IP和Modbus串行协议上提供。此外，Y-Flow®可以轻松地与当今市场上可用的各种无线通信选项（蜂窝，无线电频谱和卫星）集成
4.预先配置的应用程序数据库
A pre-configured application database is pre-loaded into the Y-Flow® based on the customer’s application. This significantly minimizes setup and startup time when the flow computer is deployed in the field. More importantly, the flow computer stores 40 days’ worth of hourly and daily flow data that can be retrieved and printed with ease.
