Innovation and Technologies by Nozzle Eng: 'Dot One' - the new refueling nozzle with electronics inside.

 Nozzle Eng. is glad to present the new series of electronic nozzles DOT ONE for dispensing liquid fuels. The official presentation will be done during Automechanika at our stand 10B81. Visit and see the future with your own eyes …
The 'Dot One' electronic nozzle is the result of the field work and projects which the company carried out throughout years. 'Dot One' embodies all Nozzle Eng's knowledge, representing the state-of-the-art product of the company.
 
Designed from leading-edge concepts and leveraging well-established electronic and software technologies, 'Dot one' represents a product with no equal. Optimizing hydraulics and using analog and digital sensors to implement safety functions, Nozzle Eng has created a refueling nozzle with original features, not replicated by any other device on the market.
 
The development of 'Dot One' has been involving experts and companies specialized in the building of particular high-tech assembly (such as high precision electronic sensors). The R&D Department of Nozzle Eng has been responsible for the design, supervision, integration and configuration of the various parts adapting them to the specifications imposed by such a fueling device.
 
In the last few years, thanks to the feedback from companies in the petrol industry, like oil companies and dispenser manufacturers located in various continents, Nozzle Eng has optimized both the aesthetics and the engineering of 'Dot One'. The result allows a high level of safety standard combined with an outstanding usability and management, in full compliance with all applicable regulations (UL, ATEX, TUV, EMC, ...)
The most exclusive attribute of the nozzle is its software control. It represents an advancement in the industry which opens new possibilities and new scenarios for the fuel dispensing systems. First and most importantly, it impacts on safety. The enabling factor of augmented safety is in the set of sensors which monitor the status and conditions in some points of the device. The software reads the data coming form the sensors and determines how to handle the situation applying the programmed logic to all the inputs in just a few milliseconds time.
 
The function which automatically shuts off the electro-valve to avoid fuel splash outs uses ad-hoc sensors installed in the spout to recognize the fluid or even the foam approaching the upper level of the tank. These sensors have been designed in order to provide high reliability and to detect the appropriate physical properties of fuels and foams. Additional valuable functionalities have been implemented. A digital
accelerometer reads both the horizontal and vertical angles and detects whether the device is moving above a speed threshold. The software automatically deactivates the control buttons or in case the fueling is in progress stops the flow by shutting off the electro-valve. Fueling is thus not possible while walking around the petrol station or driving away by car. Also an alarm is triggered whenever the nozzle is in the tank for a certain number of seconds and no operation occurs. This is to avoid damages produced when a vehicle moves away with the nozzle still inserted in the tank. Angles and timeouts are all configurable and may be set up according to the specific installation.
 
One of the requirements which emerged from the Nozzle Eng's study was a support of the work-flow and operations of maintenance. Two tools have been designed to meet this requirement. The first is a wireless interface on board of the nozzle by which the control software logs the status and the completed transactions on a remote receiver placed either on the dispenser or in the service station office. The log journal reports key facts about the life of the nozzle and can be queried to aggregate data per period or type of event. The second tool is the Nozzle Eng Management System (NEMS) which is a web application offering a visual environment to remotely monitor a set of nozzles, track their conditions and possibly plan in advance the on-site maintenance operations. The warning levels related to the nozzle usage are all configurable with a granularity ranging from the whole fleet to a per nozzle basis. The tool is particularly useful to keep control of maintenance and to prevent total or partial denial of services.
 
Finally, the architecture of the nozzle is suitable to accommodate extra needs without affecting the existing functionalities. Some operators have already thought about the possibility of using the LCD screen to display advertisements (which can be uploaded through the wireless interface) or to introduce logging data useful for fleet management and even integrate the NEMS with existing fuel management software.
Dot One is available in 4 versions: diesel, gasoline with vapor recovery, gasoline with vapor recovery with on/off valve and DEF/ADBlue. All models are compatible with existing systems with certificated connections and pressure devices.
