Yokogawa’s Y-FlowTM RTU is an effective and precise remote management controller that allows for maximized production while ensuring the production process is safe and reliable. By taking inputs from various instrumentations, the RTU will process and monitor the data through pre-programmed or user-designed applications. The data is logged, stored and transmitted to a host/SCADA system via Ethernet (Modbus Serial, Modbus TCP) or wireless communication protocols.
Yokogawa’s Y-FlowTM FFC provides timely, accurate and reliable measurements anywhere, anytime. By combining the Y-FlowTM with Yokogawa’s state-of-the- art coriolis, vortex and multivariable meters, accurate gas measurements are easier than ever. From orifice flow to steam measurement, Yokogawa’s Y-FlowTM FFC provides superior accuracy and reliability that ultimately reduces CAPEX and increase profit.
In an industry where safety and reliability is priority, Yokogawa’s Y-FlowTM provides the control and peace of mind for operators and engineers alike. From emergency shutdowns to valve control and positioning, Yokogawa’s Y-FlowTM is there to ensure the process is safe and sound.
Specifications for the EJX910A are condensed for the purpose of this document. Please see GS01C25R01-01EN for more detailed information.
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. Out of all the Yokogawa pressure transmitters, the EJX910A has the best accuracy for combined DP and SP measurement, which makes it an excellent choice for flow calculations with a RTU.

In addition to the standard I/O offered on the processor board, the FFC and RTU have the capability to expand I/O count by adding the Y-FlowTM extender board. Furthermore, the extender board allows for Opto 22 G4 AC and DC input/output modules for applications that require switching loads such as DC relays, solenoids, motor starters, lamps and indicators.
