Flowmeter

Abstract

Flowmeters, by means of the liquid director located on the cylindrical body with two open ends, measure with the rotation of the completely thermoplastic helical shaped wheel (20) placed inside the body in a way that directs the water while passing through the helical shaped wings of the inlet and outlet flow directors (30, 40) during the passage of the liquid. Since the wing angles on the outlet flow director (40) have the same direction as the helical impeller (20) in order to ensure device safety on the device to which it is connected, it does not move during the reverse flow of the liquid passing through the body (10). These sensors allow the easy calculation of water flow rates by using a suitable flow formula by counting the electrical pulses at the outlet of the liquid passing through it and allow calculations to be made by measuring the pulse frequency according to the flow rate. The completely thermoplastic helical-shaped wheel (20) in said product can be characterised by its design.

Description

FLOWMETERTechnical Field of The Invention

[0001] This invention is a flowmeter that can be used in all devices with a liquid flow system, comprising a cylindrical body with two open ends (10), and inside this body (10), a flow measurement sensor that has first an inlet flow director (30) and then an outlet flow director (40) positioned in the flow direction, has poka-yoke pin sockets at both ends that prevent reverse installation between these two flow directors (30, 40), can be installed without any errors, and completes the grouping with a helical- shaped wheel (20) that allows the measurement of the liquid passing through the body (10).

[0002] This flowmeter is a flow measurement sensor with a helical- shaped wheel (20) that is the same as the outlet flow director and thus can measure flow, and does not use an external additional metal pin that holds the wheel on the axis between the flow directors (30,40).

[0003] During the flow of liquid through the flow meter, the working shaft is suspended by the positive pressure created on the static liquid filled in the bearings and thus reduced to a minimum. It is characterised by the fact that only the impeller sides of the bearings are open, the gap between the impeller and the bracket is very small, both the liquid in the bearings remains static and the particles in the liquid flowing through the sensor are prevented from entering the bearing, thus eliminating the effects of compression or slowdown that will be caused by pollution. At the same time, said product is characterised by the fact that it does not hold metal-containing materials and has an easy-to-install feature by means of its special completely thermoplastic helicalshaped wheel (20) (in a single-piece structure without any additional metal pins), is more sensitive with its wireless plain pcb, is a sensor that is economical, lighter, longer-lasting and can be used in different sectors.

[0004] Flowmeters are used independently of any device or sector for the purpose of measuring any liquid flow in daily life areas, and are frequently used especially in combi boilers, boilers and similar devices. The present invention is the sensors used to measure the amount of liquid passing through it. Said sensor is used in order to obtain accurate results without affecting the temperature and pressure of the measured liquid and the measured flow rate of the liquid.State of the Art

[0005] The flowmeter used in the state of the art provides measurement by keeping fluids such as gas, air and liquid under control. This sensor provides the number of turns of the rotating propeller by means of the water passing through it and this number of turns is measured with the help of magnetic sensors.

[0006] Said flowmeters help to measure the amount of liquid flowing in the system and are used to improve the sensitivity, resolution and accuracy of liquid measurement to the maximum level. Mostly metal and glass raw materials are used. However, other materials such as thermoplastic can also be used. In metal and similar heavier products, problems such as rust / corrosion can be encountered over time, and problems such as deterioration in flow and measurement may occur in the future. With the use of thermoplastic materials, rust, corrosion and deterioration in flow problems are prevented.Brief Description of the Invention

[0007] Flowmeters, by means of the liquid director located on the cylindrical body with two open ends, measure with the rotation of the completely thermoplastic helical shaped wheel (20) placed inside the body in a way that directs the water while passing through the helical shaped wings of the inlet and outlet flow directors (30,40) during the passage of the liquid. Since the wing angles on the outlet flow director (40) have the same direction as the helical impeller (20) in order to ensure device safety on the device to which it is connected, it does not move during the reverse flow of the liquid passing through the body (10).

[0008] These sensors allow the easy calculation of water flow rates by using a suitable flow formula by counting the electrical pulses at the outlet of the liquid passing through it and allow calculations to be made by measuring the pulse frequency according to the flow rate. The completely thermoplastic helical- shaped wheel (20) in said product can be characterised by its design.Detailed Description of the Invention

[0009] Flowmeters are devices that measure fluid substances such as gas, liquid or air passing through a system in terms of “unit mass’7”unit time” or “unit volume” / ”unit time”. They measure electronically or mechanically and transfer the measurement results to the display panel. In other words, a flowmeter is a type of device used to measure the volume or mass of a gas or liquid. The present invention is characterised by a system that prevents metal-containing substances from adhering to it by means of the special (completely thermoplastic) helical- shaped impeller (20) in devices with a liquid flow system, does not use an additional metal pin externally on the helicalshaped impeller (20), has specially shaped liquid-directing helical- shaped wings (21) so that the liquid can pass with maximum flow on the impeller, and provides direction to the water, and has flow directors (30,40) with wing angles in the same direction as the winged helical- shaped impeller (20). Additionally, it is characterized by being completely made of thermoplastic materials, thus resistant to rust / corrosion and robust, by being able to be easily, flawlessly and accurately grouped by holding onto the flowguide holding slots (11) specially shaped for them inside the body (10) without the need for additional welding or screwed assembly by means of specially shaped tabs (31,41, 32,42) on the inlet and outlet flow directors (30,40) and mutually interlocking (Poke Yoke) grouping system to prevent incorrect grouping, by having a modular, completely thermoplastic body (10) that allows it to have sensors with three different capabilities / features, and also by being lighter, more economical and longer lasting with wireless bare pcb.

[0010] The flow directors (30,40) that are located on the inner surface of the thermoplastic body (10) consisting of a single piece with a cylindrical inner shape, at the inlet and outlet sections of the body (10) and are shaped as reciprocal interlocking poka-yokes that prevent incorrect grouping completes the grouping process by fitting perfectly, easily and without error into the pin slots (33,34) that are located in the wheel centres by means of poka-yoke pins (22,23) that are made of one piece, are thick on one side and thin on the other, do not allow for faulty assembly, are placed on the flow director holding slots (11) that are located on the inlet and outlet sections of the flow meter with a cylindrical inner body (10).

[0011] The present invention is characterised by being a flow measurement sensor that comprises a cylindrical body with two open ends (10), an inlet flow director (30) and an outlet flow director (40) that come out with the body inside this body, and helicalshaped wheels (20) positioned between this inlet flow director and outlet flow director and providing measurement of the liquid passing through the body, and completes the grouping perfectly without the need for ultrasonic welding, hot plate and similar techniques.

[0012] Another feature of the invention is that during the flow of liquid through the flowmeter, the working shaft is suspended by the positive pressure created on the static liquid filled in the bearings and thus the friction is reduced to a minimum. The fact that only the impeller sides of the bearings are open and the gap between the impeller and the bracket is very small prevents both the liquid in the bearings to remain static and the particles in the liquid flowing through the sensor from entering the bearing, thus eliminating the effects of compression or slowdown caused by pollution.

[0013] Another feature of the invention is that by means of its special completely thermoplastic helical- shaped impeller (20) (in a single-piece structure without any additional metal pins), it does not hold metal-containing substances and has an easy- to-install feature, it is more sensitive with a wireless bare pcb, and it is an economical, lighter, long-lasting sensor that can be used in different sectors.

[0014] Another feature of the invention is that since the impellers do not compress, the water here is directed in a way that it cannot reach the bearing area in any way.

[0015] Another feature of the invention is that by means of the wing directions of the brackets and impellers in the system being the same, the liquid comes and goes directly, and thus there is no turning effect on the wing structure.

[0016] Another feature of the invention is that, in said product, the helical- shaped wheel structure and the wing tips are made completely round, preventing the magnetic field from spreading in certain places and preventing the compression or accumulation of ferromagnetic materials in these areas.

[0017] Another feature of the invention is that, with the drop-shaped structure it has, the amount of particles is reduced and the sensitivity in measurements is increased.

[0018] Another feature of the invention is characterised by the system defined by the presence of a V (angled and flat shaped) impeller that prevents the liquid inside from rotating by hitting the blind spots of the impeller with a magnetic feature in the reverse flow, but has no effect in the normal flow.

[0019] Another feature of the invention is that it provides assembly without the need for any techniques such as ultrasonic welding, hot plate, screws or the like for the grouping process by means of the flow director holding slots (11) specially positioned inside the body (10) for the tabs (31,41) shaped on the inlet and outlet flow directors, and thus easily completes the grouping process.

[0020] Another feature of the invention is that the inlet and outlet flow directors (30,40) in said product can be easily, flawlessly and accurately grouped by holding onto each other without the need for additional welding or screwed assembly to the flow director holding slots (11) specially shaped for them inside the body (10) by means of the specially shaped (31,41) tabs (32,42) on them and the mutually interlocking (Poke Yoke) grouping system that prevents incorrect grouping.

[0021] Another feature of the invention is characterised by the fact that the wing angles on the inlet and outlet flow director (40) have wing angles in the same direction as the helical impeller (20), but do not measurements to be made during the reverse flow of the liquid.

[0022] Another feature of the invention is characterised by reducing the amount of particles and providing high sensitivity by means of the drop form of the impeller.Brief Description of the Drawings
