The odorizing unit control system was designed to automatically control the process of supplying odorant to a gas pipeline in proportion to the actual natural gas flow with a given degree of odorizing.
The odorizing unit control system is based on the REDUL B400 HMI/CPU and the REDUL B200 I/O modules. Alternatively, the system can be equipped with a third-party HMI panel with Modbus TCP connection. Connections to the measurement equipment and actuators are protected with the intrinsic safety barriers.
The REDUL B400 is an HMI for the operator to configure the system and parameters of the process and then monitor technological information, display events and access event logs. Information from the system can be sent to external systems via digital interfaces, like RS-485 or Ethernet. Support of printers and keyboard by the B400 controllers and external monitors via DVI port allow for creation of a complete workstation.
