Definitions

  • the present invention relates to a pump for liquids in which the amount of fluid pumped has to be measured.
  • the invention relates to a pumping apparatus liquid lubricants (oil) or fuels (diesel oil etc.) in which the amount of fluid pumped has to be measured.
  • the pumps used for fluids with medium-high viscosity are either of gear, positive displacement, liquid ring, centrifugal type pumps, etc.
  • Such types of pumps require usually a accurate control of the fluid flow rate pumped.
  • the fluid flow rate supplied must be measured with precision for avoiding billing errors that would affect either the user or of the owner of the petrol pump.
  • a fluid pumping and flow rate measuring apparatus comprises:
  • the part of the pump body that is located near the delivery outlet of the fluid houses said sensor that detects the passage of the fluid and transmits a signal (analogic or digital) proportional to the amount of fluid pumped.
  • the signal sent from the flow rate sensor is acquired by the electronic circuit located in the motor, is computed and displayed or sent to another remote device, as a measure of the delivered litres of fluid.
  • the device in addition to the sensor for measuring the fluid flow rate, is equipped with at least a sensor for detecting the pressure in the pump body.
  • the data recorded by this sensor are computed by the electronic circuit which, being operatively connected to means for turning the pump on or off, turns the pump on or off, depending on critical pressure conditions.
  • the apparatus can be equipped also with at least a temperature control sensor. Therefore, all the sensors are integrated in the pump and operated by electronic boards connected to each other, and mounted in the pump, on a control console or other remote device.
  • the fluid pumping and flow rate measuring apparatus detects the amount of fluid that exits from the pump, without being influenced by possible looping of fluid, bypasses etc..
  • the flow rate value, recorded by the sensor can be displayed directly on a display monitor arranged on the pump.
  • the flow rate value can be transmitted to an external unit through a remote connection (net of personal computer, RS-232 interface, etc.) and displayed on the monitor of a personal computer, of a client computer etc.
  • a remote connection network of personal computer, RS-232 interface, etc.
  • the pump has to be located in a place where an operator is not present.
  • a system for stopping the pump when a predetermined amount of liquid has been delivered.
  • an apparatus 10 for pumping and for measuring the flow rate of a fluid, in particular but not exclusively fuels, lubricants, oils comprises a pump 10 with a fixed part or pump body 14, which contains a rotating part 17 usually called impeller, a motor 15 that operates impeller 17, a sensor 13 for measuring the fluid flow rate, a control box 1 containing a control unit associated to a display 2.
  • pump body 14 has an inlet 11, or suction inlet, and an outlet, or delivery, 12 located tangentially to the impeller.
  • a motor 15 by means of an armature 16 on whose axis the impeller 17 is keyed, brings the latter into rotation.
  • the fluid enters body 14 of pump 10, through inlet 11 and is conveyed by the centrifugal force received by impeller 17 towards outlet 12, for being delivered in the delivery duct.
  • the fluid crosses sensor 13, located in a housing made near outlet 12. This sensor 13 produces a signal, analogic or digital, proportional to the amount of fluid pumped, that is sent to a computer 1 located above motor 15.
  • the senor 13 is a wheel with two magnets 23 that send pulses to a proximity sensor 24, that are counted by control unit 1 and displayed on display 2.
  • buttons 3, 3', 4, and 4' that allow to set device 10.
  • an operator can choose displaying on display 2 the values of the partial/total fluid flow rate, or can cancel the count of the delivered litres of fluid, or can also set the functions of control of the pump or of other external apparatus.
  • the hydraulic part, at the delivery outlet provides the addition of a housing for sensor 13.
  • This integration allows to reduce substantially the size and the costs of the unit pump-flow-counter, with considerable reduction of time of installation.
