  • Data from an existing level probe are logged additionally in order to detect the tank level .
  • Ultrasonic echo sounders Type NivuCompact have been used at the throttle discharge as well as on the discharge edge. The echo sounders are directly powered by the data logger.

  • Alarms are triggered using an instruction list stored in D2W as soon as the pre-set alarm requirements have been fullfilled
