The disclosure relates to monitoring systems and methods. A first aspect relates to a monitoring system for use when loading fluid from a source tank to a destination tank via a loader apparatus, the monitoring system having: a first input for coupling to the source tank in order to receive a source tank input signal; a second input for coupling to the destination tank in order to receive a destination tank input signal; a sensor input for receiving a sensor signal from a fill level sensor in the destination tank; circuitry configured to determine: a first status of an electrical continuity between the loader apparatus and the source tank in accordance with the source tank input signal, a second status of an electrical continuity between the loader apparatus and the destination tank in accordance with the destination tank input signal, and a fill level status in accordance with the sensor signal; and a single user interface for displaying the first status, second status and fill level status.

A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide data to the processor. The processor is configured to recall information from the memory, to compare the information to the data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison.

A fuel-urea injection apparatus including a common inlet for a vehicle may include a filler neck including the common inlet, into which a fuel injection nozzle and a urea injection nozzle, are inserted, a detector detecting whether the injection nozzle inserted into the filler neck is the fuel injection nozzle or the urea injection nozzle, a switchover valve mounted at a common injection pipe connected to the filler neck, a urea injection pipe connected between a urea outlet of the switchover valve and a urea tank, a fuel injection pipe connected between a fuel outlet of the switchover valve and a fuel tank, and a controller controlling an operation of the switchover valve in accordance with the injection nozzle detected by the detector as being inserted into the filler neck to supply either fuel or urea to the corresponding outlet of the fuel and urea outlets.

A variable inlet device for a vehicle includes a first pipe and a second pipe arranged in parallel to each other, and a variable injection pipe configured to allow an exit thereof to be selectively connected to an entrance of the first pipe or an entrance of the second pipe by a rotation movement and a back and forth movement.

The present invention relates to a mobile cleaning unit for dilution, storage and dispensing of cleaning products (10), that forms a storage-organization cabinet unit (1) mounted on castor wheels (1e) comprising: at least one dilution and dispensing device (2) and a plurality of supply pipes (2-2a, 2-2b, 2-2c) for supplying a plurality of concentrated detergent products stored in a plurality of large reservoirs (8) filled at least in part with various different concentrated detergent products, and a plurality of label dispensers (3) for dispensing labels of various types, and a plurality of compartments (7b) each adapted so as to contain a plurality of the said small container (7) bearing labels of one of the different said cleaning products respectively in the said different compartments.

An apparatus and system are disclosed for fluid transfer. The apparatus includes a fluid receiver that includes a receiver base having an inlet and an outlet. The apparatus also includes a tubular cylinder having an inlet and an outlet, where the outlet of the tubular cylinder is coupled to the inlet of the receiver base. The tubular cylinder has a keyed outer surface, which in one embodiment, includes at least one surface feature extending annularly around the surface of the tubular cylinder. The surface feature engages with at least one tumbler in a fluid nozzle. The system includes the fluid receiver and a fluid nozzle. The fluid nozzle, in one embodiment, has an arrangement of tumblers that are positioned adjacent an inlet of the fluid nozzle and configured to engage the keyed outer surface of the fluid receiver.

A universal closure valve adapter attachable to a neck wall of a first container that forms a periphery of an opening having a diameter. The universal closure valve adapter includes a closure valve assembly that is attachable to a closure valve assembly of a second container. A flange transversely extending from the closure valve assembly of the first container. The flange includes a plurality of tank neck engagement assemblies. Each of the plurality of tank neck engagement assemblies are spaced apart from each other about the flange.

A flow control valve is provided including a valve aperture in a valve body configured to convey fuel from an inlet to an outlet, a valve element configured to close the valve aperture to block flow of the fuel, a valve actuator configured to shift the position of the valve element between a closed position and an open position, and an antifraud circuit. The antifraud circuit is configured to receive a signal to open the flow control valve, determine if the signal is legitimate based on a signal characteristic, cause the flow control valve to shift to the open position in response to determining that the signal is legitimate.

A withdrawal system (1) for a container (2) and comprises an immersion pipe (4) mounted on and projecting into the container (2) as well as a withdrawal head (5) that is attachable to the immersion pipe (4) by means of a rotary connection. The withdrawal head (5) attached to the immersion pipe (4) is secured by means of a mechanical locking unit.

A variable inlet device for a vehicle includes a first pipe and a second pipe arranged in parallel to each other, and a variable injection pipe configured to allow an exit thereof to be selectively connected to an entrance of the first pipe or an entrance of the second pipe by a rotation movement and a back and forth movement.
