Abstract: A digital liquid flow rate meter that comprises a body adapted to delimit a conduit for conveying liquid with two connectors which provided respectively with male threading and with female threading. In the conduit a turbine is inserted provided with a magneto that transmits impulses to a microprocessor comprised within the body and provided with an electronic card complete with display for direct reading of the flow rate of liquid conveyed. The turbine is associated with a shaft that transmits selectively at the ends, according to the direction of travel of the liquid, an axial thrust to corresponding supports that are inserted in the conduit. The shaft is provided with anti-wear elements that are adapted to ensure operation in the absence of wear in both directions of travel of the liquid.

Abstract: Automatic liquid dispensing gun, comprising a structure provided with a connector for coupling to a pipe for feeding a liquid and with a nozzle designed to be inserted in a container designed to receive a dispensed liquid, the nozzle comprising a duct for dispensing the liquid which is controlled by an actuation handle and an air intake duct which reaches a device adapted to block the dispensing of the liquid when the inflow of air ceases, the gun further comprising an element that is sensitive to the passage of the liquid and is connected to a sensor which transmits signals to an electronic board capable of recording the dispensed quantity of liquid, with transmission of the data item related to the dispensed quantity to a display accommodated within the structure.

Abstract: A portable fuel transfer unit comprising a plurality of functional elements, such as an electric pump connected to the intake with a flexible hose provided at the end with an adapted filter with a one-way valve and to the delivery with a flexible hose provided with a dispensing nozzle at its end; the unit comprises a shell which is divided into two detachably connected sections and has the electric pump fixed to a first section and is adapted to contain all of the functional elements when the two sections are assembled.

Abstract: A liquid flow-rate digital measurement device, comprising a turbine inserted in the liquid conveyance duct and associated with a shaft which transmits, at a first end, an axial thrust to a corresponding support, a shaft of the turbine being made of stainless steel and being provided, at the first end, with a tip which is made of wear-resistant material, an element made of wear-resistant material being inserted in the plastic body of the measurement device in such a position as to abut against the tip of the turbine shaft.

Abstract: An electronic control device for a pump, particularly for transferring liquids, comprising a central control unit, which is adapted to drive an electric motor which is designed to operate the pump, at least one motor temperature sensor, which is adapted to send a temperature signal to the control unit, at least one motor current sensor, which is adapted to send a current signal to the motor, and at least one power switch, which is adapted to drive the motor, the power switch being driven by the control unit in order to control the motor according to the signals of the temperature sensor and the current sensor.

Abstract: A gun for dispensing fluids having a positionable spout comprises a handle provide with a trigger which is posteriorly coupled, by means of a rotatable connection, to a flexible fluid feed pipe and which anteriorly bears a spout destined to be introduced into an access of a container to be filled with fluid. The spout is sealedly connected to the handle by means of a connection which is rotatable about an axis of rotation which is not parallel to an axis of the handle.

Abstract: The command device for dispensing fluids comprises a handgrip posteriorly constrained to a fluid feed pipe and anteriorly bearing a spout connected to the feed pipe and destined to be introduced into an access mouth of a container to be filled with the fluid. A trigger can selectively assume at least a first, closed position in which a connection between the spout and the fluid supply pipe is closed, and a second, open position in which the connection is opened. A mobile lock can on command assume at least a first, locking position, in which the trigger is maintained in the open position, and at least a second unlocked position in which the trigger is free to return into the closed position.
