Dosaodor-D Odorant Injection System Controlled by Type ROC809 Remote Telemetry Unit

Dosaodor-D Odorant Injection System Controlled by Type ROC809 Remote Telemetry Unit Type Dosaodor-D is a computerized odorant injection system for natural gas using patented solenoid injector technology that eliminates the need for plunger pumps.

The solenoid injectors provide odorant injection accuracy to be maintained over the entire flow range of the system, approaching infinite turn down.

Automatic calibration during operation adjusts for any changes in mechanical components and also detects failures for alarming. Report by exception alarming is a configurable option.

The system can also be configured to use redundant injectors and/or an emergency backup or bypass absorption system.

Features and Benefits
  • Uniform distribution of odorant due to frequent smaller injections and enhanced absorption from the wick insertion
  • High turndown ratio. For example, one specific configuration would evenly distribute odorant at flow rates from 2000 to 1 200 000 SCFH (53,6 to 32 160 Nm3/h) with no mechanical adjustment
  • Automatic calibration of injection system during normal operation ensuring consistent odorization
  • Environmentally friendly with no venting of gas or odorant while operating
  • Extremely low maintenance cost
  • Variety of redundancy and backup options for reliable odorization
  • User-friendly configuration software
  • Standard and scalable hardware platform that supports additional station I/O for AGA flow calculations and PID control algorithms
