Fisher Remote Operations Controllers (ROCs) are general-purpose RTUs designed for a variety of measurement and control applications, including gas flow measurement for both production and metering applications.
The family of Fisher ROC RTUs starts with the ROC 306, ROC 312 and ROC 364 products for low to medium point-count applications requiring gas flow measurement and control capability.
For more sophisticated gas flow measurement and control applications the ROC 800 series Remote Operations Controllers are available. These include the ROC809 and ROC827 RTUs which are ideal for field installations where the monitoring, measurement and control of processes and equipment are required.
The ROC800-Series has the ruggedness and low power consumption of an RTU; the audit trails and historical data of a flow computer; and the scalability, speed and control capability of a PLC in a single device. It is ideal for field installations where the monitoring, measurement and control of processes and equipment are required.
