Description

Flowmeter capable of detecting leakage

The invention relates to a flow meter, in particular to a flow meter capable of detecting the possibility of leakage and the possibility of leakage in the water environment.

Press, a flow meter is a measuring instrument that is installed in a fluid line and is constantly in contact with a fluid to measure and record the flow rate, most commonly a water meter or a gas meter. In the case of the current flow meter for measuring the amount of water, the known use is not only for measuring the flow (water) amount, but also for developing a function that can measure the flow rate and sense the flow direction, but has not seen it before. A flow meter that detects leaks in the pipeline exists. In the ecological environment where the flow meter used for metering water quantity is installed, most of the pipelines are buried deep under the surface, especially in the water pipe network. Because the pipeline connection is complicated, and there are many devices attached to the pipeline, It is buried under the surface for a long time, so the leakage of the pipeline under various pressures, earthquakes and the internal pressure of the internal pressure of the pipeline can occur at any time and everywhere. This can often be seen on the road surface. certificate. In addition to leakage in the pipeline, the flowmeter itself may be affected by various pressures between the pipelines or due to mechanical failure factors, and leakage may occur. Whether it is leakage in the pipeline or leakage on the flowmeter, in addition to causing waste of the flow (water) body, the most important is the inexplicable economic loss of the supply end (such as the water company) or the use end (such as the water user). Ewing's unknown leakage, resulting in long-term leakage, the accumulated economic losses are particularly serious, and the actual value of troubled research and development improved.

In view of the above-mentioned deficiencies, the inventors have been actively conceiving research and development of flowmeters capable of detecting leakage by utilizing the deep experience of the relevant industries for many years, and the invention has been produced after many efforts.
The main purpose of the present invention is to provide a flow meter that can detect leakage and thereby estimate the likelihood of leakage and the possible amount of leakage.
Another main object of the present invention is to provide a flow meter that can detect leakage to facilitate timely repair or replacement to avoid waste of fluid resources.
In order to achieve the above object, the present invention provides a flowmeter capable of detecting leakage, comprising a body having a plurality of nozzles into and out of a water supply flow, wherein the nozzles communicate to form a passage through which the water supply flows. And a metering device mounted on the body for measuring the flow rate flowing through the body to correspondingly obtain a flow rate value; wherein the flow meter is provided with a leakage detector connected to the metering device Receiving the instantaneous flow value and the total flow value measured by the metering device for the fluid flowing through the flow meter; the leak detector can set a detection period and a detection value for the instantaneous flow value and the total flow value to During the set detection period, the instantaneous flow value and the total flow value are compared with the set detection value, thereby estimating the leakage possibility and the leakage possibility of the water environment of the flow meter.
In the above-mentioned flowmeter capable of detecting leakage, the detection period is one or more.

With regard to the present invention, the technical means and the achievable effects of the present invention will be described in detail with reference to the accompanying drawings.
The present invention is described by way of an embodiment in which a flow meter for measuring the amount of water is used. Referring to the first and second figures, the embodiment of the present invention is a flow meter 1 , which comprises a body 10 having a plurality of nozzles 101 for flowing in and out of a water supply flow and an outlet 102 for upwardly flowing out. The nozzles 101 are connected to each other to form a passage 103 through which the water supply flow flows; and a metering device 11 is disposed in the socket 102 for measuring the flow rate flowing through the body 10 to obtain a flow value correspondingly. And the flow rate value is displayed on the flow meter 1 by a display portion 12 (for example, a display table), and/or the flow rate signal is transmitted to the remote receiver via wire or wireless for subsequent use. The flow meter 1 of the embodiment of the present invention can be divided into an impeller type flowmeter, an electromagnetic flowmeter, an ultrasonic flowmeter, a vortex flowmeter, etc. due to different modes of operation of the internal metering device 11--- The flow meter, regardless of the type of flow meter, can be used in the present invention. Therefore, even if the flow meter is not in the above listed modes of operation, it can also be used in the present invention and is included in the patent scope of the present invention. Inside, I would like to give it to Chen Ming.
As long as the water flow body 1 continues to flow, the flow rate value derived therefrom continues to increase, so that the flow rate value displayed on the display unit 12 is also cumulatively increased. However, the rate of increase in flow rate will vary during the day. Generally speaking, when the water consumption is high (for example, when washing in the morning and evening), the speed is increased faster, and when the water consumption is small (for example, when sleeping late at night), the speed is increased slowly. If there is no water at all in the middle of the night (or a certain period of time), but the flow meter 1 is still being metered (the display unit 12 is slowly increasing cumulatively), it is apparent that there is a leak.
Therefore, in addition to the above-mentioned structural components, the flowmeter 1 of the present invention further includes a leakage detector 13 disposed in the flowmeter 1 and can be installed inside the metering device 11 or installed in the space of the channel 103; Referring to the third figure, the leak detector 13 is connected to the metering device 11 and can receive the instantaneous flow rate value and the total flow rate value measured by the metering device 11 when the fluid flows through the flow meter 1, and the leak is The damage detector 13 can set a detection period and a detection value for the instantaneous flow value and the total flow value, and the detection period and the detection value can be adjusted according to the water ecology, for example, for the general daytime home type. The user can set the detection period to be late at night (for example, 02:00~04:00), and the detection value can be set to be lower; for example, for the general daytime no-home class user, The detection period is set during the day (for example, 10:00~12:00), and the detection value can also be set to be lower. Under the same principle and function, the detection period set is not only one, but also more than one. For example, for normal working users, the detection period can be set once in the morning (for example, 10:00~12:00), once in the afternoon (for example, 14:00~16:00), and once in the middle of the night (for example, 02:00~04: 00), so that the leak detection situation can be discovered early by performing continuous detection of intensive multiple times at the time of completely unmanned water.
Both the metering device 11 and the leak detector 13 in the present invention are preferably equipped with a soft and hard electronic component to achieve the main function of electronic metering and detection comparison. When the detecting user generates an instantaneous flow value and/or a total flow value exceeding the set detection value within the set detection period, it indicates that the user has a possibility of leakage, and thus will be in the display unit. 12 displays a suspicious display of leakage, and/or transmits the suspected leaked signal to a remote receiver via wire or wireless for the management to know. However, it is not a suspicious one to determine that a leak has occurred. Therefore, the leak detector 13 can detect a user who is suspicious of leakage for a long period of time (multi-day and/or multi-period), and can detect the change. The time period and the change (up or down) detection value and other methods are used to cross-determine the leakage possibility and the leakage possibility of the leaky suspicious household, and the leakage potential may be estimated on the display unit 12. The display of the sexual and possible quantities, and/or the transmission of the estimated possibility and possible amount of leakage is transmitted to the remote receiver via wire or wireless for the management to know.
It can be seen from the above description that the present invention mainly provides a leakage detector in the flowmeter, the flowmeter includes a body having a plurality of nozzles into and out of the water supply flow, and the nozzles are connected to form a water supply. And a metering device mounted on the body for measuring a flow rate flowing through the body to correspondingly obtain a flow rate value; the leakage detector is connected to the metering device to receive the metering device The instantaneous flow value and the total flow value measured by the fluid flowing through the flow meter; and the leakage detector sets one (including) detection time period and one detection value for the instantaneous flow value and the total flow value to The instantaneous flow value and the total flow value are compared with the set detection value during the set detection period, thereby estimating the leakage possibility and the leakage possibility of the water environment of the flow meter. The excellent function of the invention is that the flow meter can detect the leakage, so as to facilitate timely repair or replacement, so as to prevent the leakage situation of the water environment of the flow meter and achieve the ultimate goal of avoiding waste of water resources.
In summary, the structural components of the present invention have not been seen in the past, and the intended purpose and effect can be achieved when the patented requirements are met; however, the above embodiments are merely illustrative of the composition and efficacy of the present invention, and thus The scope of the invention is to be construed as being limited to the scope of the invention.
