  • Page 7: Introduction To The Tankradar L/2 System

    Installation Manual Introduction to the TankRadar L/2 System The TankRadar L/2 System is a monitoring and control system for tank level gauging. The system can interface various sensors, such as temperature and pressure sensors, for complete inventory control. There is a distributed intelligence in the various units of the sys- tem.
  • Page 8 Sensors Temperature Sensors Figure 1.2. Example of a general configuration of a TankRadar L/2 System. All the measured data is presented to the operator by the Operator’s Interface, which in its complete version contains inven- tory functions. A plant host computer can be connected for further processing of data.
  • Page 9 Installation Manual The basic parts of the TankRadar L/2 System are: The Radar Tank Gauge, RTG, is an intelligent explosion protected instrument for measuring the level of a product inside a tank. Four different Tank Connection Units can be attached in order to satisfy a variety of different applications.

  • Page 10: Safety

    Installation Manual Safety TankRadar L/2 equipment is often used in areas where flammable materials are handled and where an explosive atmosphere may be present. To protect both the plant and the personnel, precautions must be taken to ensure that this atmosphere cannot be ignited.

  • Page 11: Explosion Proof

    Installation on a non-metallic tank is not certified, and is not allowed. The FCC certificate for TankRadar L/2 requires that the tank is closed as far as emitted radio energy is concerned. Tanks with open manholes, external-floating-roof tanks without still pipes etc.
