  • Page 4: Overview

    Overview Under the German Water Resources Act, vessels with water-polluting liquids must be equipped with overfill prevention devices. In other countries, the corresponding national rules and regu- lations must be observed. In the case of storage tanks which are filled by tank vehicles, the overfill prevention device consists of an Overfill Prevention Sensor (e-OPS) in the storage tank and an Overfill Prevention Controller installed in the tank vehicle.

  • Page 6: Safety Instructions

    Safety instructions The safety instructions in this manual are marked as follows: If these safety instructions are not observed, it may result in the risk of accident or damage to the device/system. Useful information which ensures continued and correct operation of the system and makes your work easier.

  • Page 7: Structure And Design

    Structure and design Description The Overfill Prevention Sensors consist of a probe which extends into the tank and the height of which can be adjusted, a screw-in unit which carries the probe and a connection fitting. The probe is sealed in the screw-in unit and can be moved and fixed within the adjustment range.

  • Page 16: Connection Fitting

    Connection fitting The connection fitting is the interface between the Overfill Prevention Sensor and tank truck. Depending on the method used to fill the tank, different connection fittings are used for the connection to the Overfill Prevention Sensor: pipe fitting and wall fitting. The connection fitting can also be equipped with a security system (COP/FHS, see following chapters).

  • Page 17: Cross Over Prevention (Cop)

    3.5.3 Cross Over Prevention (COP) The Overfill Prevention Sensors may be equipped with a coded connection fitting. A specific code is allocated to each product; this is read out by the Overfill Prevention Controller in the tank truck via the socket coupler FP 903/FHS/K, and only approves the liquid delivery when the product to be delivered coincides with the stored product.

  • Page 19: Installation

    Installation Mounting When working on tanks for storage of flammable liquids, all local safety and accident prevention regulations must be observed as a matter of principle. When filling static tanks with water-polluting liquids, the tanks may only be filled up to their permitted level (see the German Water Resources Act resp.

  • Page 20: Installation Height

    Installation height In the case of tanks to the DIN standard, the response height "h" and the adjustment dimen- sion "x" needed for this can be taken from the tables in the Section "Adjustment dimension". The diameter, nominal capacity (particularly for multi-chamber tanks) and the height of the manway nozzle height including the tank lid are important in calculating the adjustment di- mension "x".
