Apparatus for measuring fluid quantities in petrol station petrol pumps with a fluid meter motor having a rotating wheel in a cylindrical tube

摘要

The petrol pump measuring apparatus includes a fluid measuring motor, through which the fluid to be measured flows, in a measuring tube in the flow path between the pump which pumps the petrol up from an underground tank to the hose. The rotation of the motor is measured by a pulse generator to which is connected a measurement value converter and the measurement values are conveyed to an electric meter with a computing unit for displaying the filling data to the customer. The measuring motor has a rotating measuring wheel (12) in the cylindrical measuring tube.
