Description

The invention relates to a portable flow rate control device for heating oil.

In recent years, irregularities and manipulations in the supply and delivery of fuel oil have become known to consumers, for example, by means of improper conversions to delivery vehicles, the oil meter was manipulated, or was increased by a certain amount, for example by 100 or 200 liters, or Secondary pipes were installed downstream of the oil meter to partially return already captured oil back into the vehicle. Ultimately, in many cases, significantly less oil was actually pumped into the consumer's storage tank than the on-board oil meter had detected, which is a fraud case.

On the other hand, since the provided with storage tanks level indicators are relatively inaccurate and can only give an overview of the level situation, so that control of an oil delivery to an accuracy of for example 20 liters or even 50 or 100 liters is completely impossible.

The object of the invention is to improve the prior art and in particular to provide an easy-to-handle control option to check the delivered oil quantity to an accuracy of a few liters and adjust it with the measurement result of the delivery vehicle at an oil delivery in an example own storage tank ,

This object is achieved by a portable flow rate control device for heating oil, with a designed for determining the amount of fuel flow meter with a Zählmengenanzeige provided on the input side with a first connection for connection to a supply hose and the output side with a second connection for connection to a storage tank.

Such a device is light and handy and can also be easily mounted on a house connection by technical laymen, so that the delivery vehicle side supply hose can be connected to the first port, which is designed as well as the existing house connection.

It is expediently provided that the first and second connections have a standard diameter, in particular 2 inches, 2.5 inches, DN50 or DN80, so that the connections correspond to the existing, standardized house connections and the corresponding connections of supply hoses of delivery vehicles.

It can be provided that the second connection is provided with a flange and a union nut for attachment to a connecting line. The first connection can only have an external thread.

The flow rate counter may provide a digital measurement signal regarding the detected flow rate, in particular to a wired or wireless interface for transmission to an external memory or other digital device such as a smartphone, personal computer or the like.

The device may comprise a memory unit in which a measurement result can be stored after completion of a measurement process or delivery process.

The device can have an isolated memory or memory area in which one or more individual measurement results can be stored forgery or tamper-proof. Such measurement results may be used in court if necessary in the event of a discrepancy between the amount of oil detected by the device and the amount of oil detected by the delivery vehicle.

It is preferably provided that the device has an input device which can be actuated by means of buttons or wirelessly for inputting a set flow rate, and an alarm device which can be triggered automatically when the set flow rate is reached. In this case, the alarm device can be designed so that an alarm is routed to a mobile phone, smartphone or an external computer.

The flow rate counter may be associated with a microprocessor unit with memory for carrying out input, output and storage operations.

Furthermore, it can be provided that the flow rate meter has a driven by the flowing oil element, which is coupled to a generator for powering electronic components. For example, the flow rate counter may have an impeller as a measuring element, which is coupled to a generator for generating electricity.

In addition, an oil thermometer for detecting the temperature of the oil flowing through can be arranged in the device.

The flow meter, memory unit and / or microprocessor, if present, can be wirelessly or wired with a external digital device, such as a smartphone or personal computer, be capable of communication, so that measurement data can be transmitted. For example, it may be provided that the flow control device outputs an encrypted, tamper-proof file in which the date, the time of the beginning and end of the supply process and the measurement result and possibly the oil temperature are included.

The invention will be explained with reference to an embodiment, reference being made to a drawing in which the only

1 a schematic longitudinal sectional view of a portable flow control device according to the invention.

1 shows an embodiment of a portable flow control device according to the invention in a highly schematic longitudinal sectional view. The device initially has a cylindrical or tubular body 2 on, at a first end 4 a first connection 6 for connection to a supply hose shown in dashed lines 8th for example, a delivery vehicle, and at a second end 10 a second connection 12 for connection to a connection line indicated by dashed lines 14 For example, has a storage tank.

The first connection 6 includes one on the main body 12 attached external thread 16 and a sealing flange 18 , wherein the supply hose 8th by means of a union nut, not shown, on the external thread 16 is fastened and with a sealing flange against the sealing flange 18 sealingly connected.

The second connection 12 includes a mounting flange 20 , against which a union nut 22 with internal thread comes to the plant, as well as a sealing flange 24 , The connection cable 14 for example, associated with a domestic storage tank is similar to the first port 6 formed and has an unillustrated external thread for cooperation with the union nut 22 and a sealing flange for sealing engagement with the sealing flange 24 on. If necessary, the sealing flange 18 and / or the sealing flange 24 be provided with a seal or be covered with an elastic sealing material.

Inside the main body 2 is a flow meter 30 arranged for the determination of the amount of by the main body 2 in a predetermined flow direction 32 , from the first end 4 to the second end 10 , flowing fuel oil is designed. The flow meter 30 is with a count indicator 34 connected, which allows a reading of the amount of fuel oil flowed through. The count quantity display 34 has a reset button, not shown, with which the Zählmengenanzeige can be set to zero.

The count quantity display 34 can work mechanically or electrically or electronically, for example as an LCD display, wherein the flow meter can deliver a mechanical, electrical or electronic or digital measurement signal. Furthermore, the flow rate counter may deliver a digital measurement signal to a wireless or wired interface, not shown, for transmitting the measurement signal to an external processing device or external memory, such as a smartphone or personal computer.

At the base body 2 Furthermore, a digital storage unit, not shown, may be arranged with the flow rate counter 30 or the count quantity display 34 is connected and in which a measurement result can be stored after completion of a measurement process.

Said memory or an isolated memory, may be designed so that one or more separate individual measurement results can be stored forgery-proof or tamper-proof therein. For example, a plurality of storage areas may be provided, wherein in each storage area, a single measurement result can be written, which can not be changed after the storage process. In the event of a discrepancy between the amount of oil detected with the device and a quantity of oil measured by a delivery vehicle, then, for example, the supplier can be prosecuted, whereby a measurement result saved in a tamper-proof manner can be used as evidence.

Furthermore, the device is equipped with a temperature sensor 38 provided with an evaluation unit 40 which is used to convert the measured quantity of oil to a standard quantity of oil at 15 ° C, provided that the detected temperature deviates from 15 ° C.

The flow control device may be provided with a microprocessor unit which receives both signals from the flow rate counter 30 as well as from the evaluation unit 40 receives to display and / or store a standard amount of oil, based on 15 ° C.

Furthermore, caps may be used to close the first and second ports 6 . 12 be provided to the interior of the device, in particular the flow meter 30 To protect against contamination and damage when the device is not in use, and also to prevent unwanted leakage of oil residue.
