A FUEL PUMP UNIT FOR A FUEL DISPENSING UNIT, A FUEL DISPENSING UNIT FOR REFUELLING A VEHICLE, AND A METHOD FOR HANDLING A FUEL PUMP UNIT OF A FUEL DISPENSING UNIT

摘要

The invention relates to a fuel pump unit (10) for a fuel dispensing unit (1). The fuel pump unit (10) comprises a pump (6) with a suction side (S) and a pressure side (P) for pumping fuel along a fuel flow path between an underground reservoir and a nozzle (7) of the fuel dispensing unit (1), at least one ultrasonic transmitter (11) arranged at the suction side (S) of the pump (6) and adapted to send out an ultrasonic signal in the fuel flow path, and at least one ultrasonic receiver (12) arranged at the suction side (S) of the pump (6) and adapted to receive the ultrasonic signal. The invention also relates to a fuel dispensing unit (1) for refuelling a vehicle and a method for handling a fuel pump unit (10) for a fuel dispensing unit (1).
