Description

SMART TYPE TURBINE FLOWMETER תוניברוט גוסמ םכח םימ דמ FIELD OF INVENTION The present invention is directed to smart type apparatus for measuring a liquid flow rate, and more specifically to turbine type liquid flowmeter.

BACKGROUND OF THE INVENTION Water is such viable product delivered to water customers by the municipal or private water delivery systems usually on a cost per unit of volume basis, generally cost per cubic meter, m³. In these systems, a water meter is typically disposed in-line of fluid pipe between Supply and Customer property to measure the amount of water flowing from the supply pipe to the customer. In order to bill the customer for water usage, it is necessary to periodically read the meter to determine the amount of usage over a fixed period of time. This process is referred to in the industry as metering or meter reading, which must be arranged in accordance with legal metrology rules .

Thus, the invention relates to liquid flowmeter, in particular, water meter, (hereafter the words liquid and water are interchangeably) developed in accordance with legal metrology rules. There International and Nationals Legal Metrology Departments are, which define the following: "…to enable economies to put in place effective legal metrology infrastructures that are mutually compatible and internationally recognized, for all areas for which governments take responsibility, such as those which facilitate trade, establish mutual confidence and harmonize the level of consumer protection worldwide".

In other words if the municipal or private water delivery / accountable systems and their consumers have agreements on water consumption, where signed "cost per m³", then water flowmeter should directly meter a m³ of water, but not a velocity of ultrasound or whatever regarding to water flow in pipe. As well as a min/max water flow head (or pressure) must be provided in the water delivery systems .

Generally, apparatus for measuring the liquid flow rate of the water utilities includes the communicating parts such as a convertor of the liquid flow into a measurable motion specifically of the rotating type in direct proportion to the liquid flow speed, a convertor of the measurable motion into measurable signal easy to digitize, specifically of the electrical signals type, which can be used for detecting the instantaneous flow and the total integrated flow, a convertor of the digitized signal into accountable data being readable to capture and transmit into the corresponding accounting system of the water delivery systems.

CN210981383U discloses a turbine type flowmeter, comprising a housing being provided with a fluid inlet, a fluid outlet, and a measurement interface being fitted with a flow measurement device; a turbine, having a blades, rotatably disposed inside the housing for transmitting a rotational force to the flow measuring device; the first fluid director and the second fluid director are symmetrically arranged on two sides of the turbine for directing fluid to the turbine to rotate it and for directing fluid exiting a fluid outlet of said housing respectively .

Note that the turbine type flowmeter and impeller type flowmeter mean one has a rotation axis along a path of liquid flow, and another has it perpendicular therein .

US8279080 discloses a remote water meter for monitoring system. A mesh network-type transceiver unit is coupled to a water meter housing having a water counting mechanism inside to transmit water consumption information as well as other sensor information, such as backflow detection, water pressure, and water metrics (e.g., residual chlorine and temperature) to a central server system via a bridge device and a corresponding mesh network. Mechanical energy from the water flowing through the water meter housing is converted to electrical energy via an energy conversion unit .

Becker et al, Energy Autonomous Wireless Water Meter with Integrated Turbine Driven Energy Harvester, Journal of Physics: Conference Series 476 (2013) 012046, discloses a fully integrated wireless, energy-autonomous water metering system. The system is powered by an energy harvester, based on a water-driven turbine wheel that is directly coupled to an electromagnetic energy transducer. The power delivered by the generator is dependent on the amount of flowing water. Therefore, the power is commonly non-continuous, fluctuant, and unstable in the voltage amplitude. To be able to report the meter readings at all times, the system should have a battery rechargeable by the generator and energizing the system during the standing time.

US7504964B2 discloses apparatus for monitoring, comprising: a meter that monitors usage of a distribution system; an electronic data recorder that processes data from the meter; an external unit that controls the processing of data in the electronic data recorder with a communication protocol; and where the communication protocol comprises, an initialization signal, an interval identification signal that identifies a present reading cycle for the data from the meter with a unique signal width of the interval identification signal, where the unique signal width comprises a multiple of a signal cycle width, and a clock signal.

In prior art the flowmeter value is greatly influenced by liquid flow velocity, liquid flow behavior (laminar/turbulence flow; low/high consumption jets), e.g. because the slipping between in-flow and dry magnets coupling, when measuring the same water volume e.g. 1 m³ (i.e. same consumption but different cost), disclosed in Competence’s Theorem: Solving Problems of Water Utilities, International Journal of Energy Economics and Policy, 2018, 8(5), 104-1https://www.econjournals.com/index.php/ijeep/article/view/6760; As well as, whatever flowmeter for measuring a liquid flow rate via measurable motion such as a rotation of the turbine is a hydraulic resistance decreasing a flow head or pressure of the liquid flow that requires to increase a hydraulic power of the water delivery systems (and water consumption cost) .

The liquid flowmeter is the functionally simple design task nested in more complex accounting task where the flowmeter structure cannot be allowed to become too complex. This is because in a typical applications in the water delivery systems, the flowmeter will be repeated so many times. The cost of each additional element in terms of money and space is therefore multiplied many times. It is therefore no simple matter to identify those functions that are sufficiently useful to justify their incorporation into the flowmeter. It is similarly no simple matter to implement those functions so that their incorporation is not realized at too high a cost.

Prior art survey conclusion: the present flowmeters for home use are or too expensive or/and sophisticated or/and do not meet the requirements of legal metrology.

Thus, municipal or private smart type water delivery systems have a strong need for low cost self-powered metering devices being remotely readable and with legal metrology properties in framework of "Smart City" automatic regulation arrangement.

It should be appreciated, however, that the present invention is not limited to these specific embodiments and details, which are exemplary only. It is further understood that one possessing ordinary skill in the art, in light of known systems and methods, would appreciate the use of the invention for its intended purposes and benefits in any number of alternative embodiments, depending upon specific design and other needs.

Reference is now made to Figs 1, 2a, 2b illustrates the overall invention presenting a process for measuring a liquid flow rate with recovering a liquid flow head of the measured liquid flow (hereafter, called process) and an apparatus for that. The apparatus represents the turbine type flowmeter 10 (hereafter, called flowmeter) installed in-line of fluid pipe (not shown).

Reference is now made to Fig. 3 illustrating the assembled flowmeter 10 installed vertically while it can be installed vertically and angled positioning as well. In accordance to the invention the flowmeter 10 includes the static parts and rotating parts shown in Fig. 10; there the static parts are axially assembled in closed structure, in which the flowmeter does not require any additional housing. Each of the static parts has circumferential ring grooves, signed as "o" to set within a corresponding O-ring for sealing therebetween in the hermetic assembling. As well as each of the static parts are circumferentially precisely positioned one to other by pins, signed as "p".

In accordance to the invention the process includes a sequence of the processes, shown in Fig. 1, where "a" is a converting the inflowing measurable liquid flow to be the pulsed liquid flow; "b" is a converting the pulsed liquid flow to be the spiral type pulsed liquid flow; "c" is a converting the spiral type pulsed liquid flow into rotating type measurable motion proportional to the measurable liquid flow; "d" is a converting the measurable motion into measurable data; "e" is a providing for the measurable data to be readable; "f" is a communicating the readable measurable data to accounting system of the water utilities; "g" is a recovering the pressure and head of the measured liquid outflowing to in-line fluid pipe. The mentioned processes are discussed below in greater details with binding to apparatus in according to the invention.

The flowmeter for measuring the liquid flow rate with recovering a liquid flow head (hereafter, a head and/or pressure) of the measured liquid flow is in four specific functional components: a convertor of the liquid flow, a convertor of the motion, a measuring means and the pumping type the head recovering means. The functional components of the flowmeter 10 are combined one other in the industrial applicability.

The convertor of the liquid flow includes, in turn, a convertor 100 for converting the inflowing liquid flow to be pulsed liquid flow, shown in Fig. 4, and the spiral fluid convertor 200 shown in Figs. 6 and 7. The convertor 100 represents an inflowing fluid receiver provided with fluid receiving camera 102, a fluid inlet 101 and a compressible bellow valve 230 operable therewith, whereby in camera 102 the compressible camera 103 is separated therein. There signed as 104 are the flowmeter assembling means. When the liquid flow does not flow the fluid inlet 101 is in closed state by compressible bellow valve 230; in accordance to process "a", as shown in Fig. 1, when the corresponding liquid pressure difference arises the valve 230 is pushed by pressured liquid mass and the fluid inlet 101 is opened. The compressible bellow valve 230 is compressed and the liquid mass is extruded in manner of pulse, flow 1003 in Fig. 1, out the compressible bellow volume, for further merging with inflowing liquid via camera 102, flow 1002 in Fig. 1. Due to a continuity of the liquid flow the measurable pulsed liquid flow is produced for further impinging upon turbine means shown in Fig. 5. The pulsed liquid flow inside of the flowmeter 10 overcomes a moment inertia of the rotatable parts therein during the measurable process and conceptually provides the measurement precise in all range of the liquid flow velocities. Fig. 5 illustrates a convertor 200 of the spiral type pulsed liquid flow for converting into measurable rotating type motion, which includes the sequentially assembled a spiral fluid convertor 200 provided with shaped blades for converting the inflowing liquid flow 1002 and extruded liquid 1003 to be a spiral type pulsed liquid flow 1004, process "b" in Fig. 1, impinging upon the turbine blades 340 of the turbine 320, flow 1005 of process "c" in Fig. 1.

A spiral type jet of liquid outflowing the turbine fluid director for impinging on the turbine blade is shown by the arrow 1004, and the turbine rotation is shown by the arrow 1005. For industrial implementation the turbine blades of this shape are performed as axially integrated two half-blades 340.1 and 340.2 via axially integration e.g. of the corresponding two half-turbines. As well as for industrial applicability the convergent nozzle 401 and divergent nozzle 411 are conically implemented as the surfaces of the details 400 and 410 respectively. The spiral type pulsed liquid flow and turbine rotation have practically one direction, wherein a force of the pulse component of the pulsed liquid flow allows to overcome the rotation moment inertia and drag force of the turbine 320 for more precise measuring mentioned above.

Fig. 11 illustrates the rotor 500, which represents the hermetic hollow housing 520 coupled with rotatable shaft in manner of symmetrical parts 510 and 511via positioning pins 540 and 541. Each part of rotatable shaft has a hermetic hollow chamber signed as 550 and 551, which, with hermetic hollow housing 520, provide the rotatable shaft 510, 511, the first and second shaft ends 321, 621, shown early in Fig. 10, turbine 320 and pump 620 disposed on the rotatable shaft to have a buoyancy in the liquid, i.e. to be a particle of the liquid mass. The microcontroller means 530 shown in Fig. 12 is disposed inside the housing 520; there as well are circumferentially disposed the inductive coils 532, and printed circuit board of the microcontroller means 531 provided with wireless communicability.

For that, the hermetic hollow housing 520 is performed by transparent silicone with corresponding hardness, no less 60...80 shore. The printed circuit boards of the microcontroller means 531 and circumferentially disposed inductive coils 532 shape a skeleton for transparent silicone hermetic housing 520.

The measured liquid flow, signed as 1008 in Fig. 1, outgoing the measuring means via divergent nozzle 411 is pumped further and saved of spiral type flow, signed as 1009 in Fig. 1, which further impinges upon the blades 1010 of the pumping fluid director 210, which, in turn, converts the spiral type liquid flow to be laminar axially directed liquid, flow 1011, for further filling the fluid accumulative camera 112 of the outflowing fluid collector 110.

Fig. 17 illustrates a single blade 215 of the pumping fluid director 210, which is optimally shaped in the present embodiment for converting spiral type liquid flow 1010 to be laminar and axially directed 1012.

Reference is now made to Fig. 18 presenting a schematic diagram of the metering circuitry of a turbine flowmeter 10. An electric signals from inductive coils 20 are received by controller 40. Numeral 30 refers to a rechargeable battery energizing controller 40. Battery 30 is rechargeable via electricity generated in inductive coils 20. The electric signals generated in response to rotation of the rotor 500 by the liquid flow to be meters is digitized in converter and processed by metering means 42 which are configured for calculating a simultaneous flow rate and accumulating fluid consumption. The obtained data are stored in memory 43. Communication unit 50 provides an access to the data stored in memory 43. According to one embodiment of the present invention, communication unit 50 is a pulse light source configured for transmitting the obtained data in a coded manner, for example, by Morse code. The transmitted data can be visually decoded by a user or by the corresponding transceiver means for further communicating to e.g. municipal or private water accountable systems. The pulse light source for transmitting the obtained data in a coded manner, for example, by Morse code is provided via transparent part of the flowmeter housing 70.
