Abstract
Description
[0001] GAS METER WITHOUT MAGNETIC AND MECHANICAL GEAR ASSEMBLY
[0002] Technical Field
[0003] The invention relates to a gas meter comprising a sensor and a numerator with LCD display connected to the sensor, which is used to reduce the cost by eliminating the rotary joint gear, axle gear assembly, magnetic coupling assembly and mechanical numerator gears and calibration gears and to provide the measurement during the rotation of the bakelite (rotating disk).
[0004] State of the Art
[0005] A gas meter is a device mounted on a gas supply pipe to measure and display the flow rate (amount of usage) of gas. The main purpose of this meter is to determine the user's natural gas consumption in cubic meters (m3) in order to accurately calculate the bill for this gas. A natural gas meter consists of a series of mechanical parts, usually housed in a metal case.
[0006] The design and manufacture of a gas meter involves mechanical engineering principles, because the efficient operation of the internal mechanisms is important. Moreover, since a gas meter is a modern metering device, it has remote monitoring and data transmission capabilities. This implies the use of smart meters and provides energy companies and consumers with real-time consumption information. In terms of safety, the device must be able to detect leaks and be protected against overpressure situations. Calibration and verification processes are carried out regularly to ensure that the gas meter consistently provides accurate readings. Finally, energy management and data analysis involves using the consumption data provided by smart gas meter systems to optimize energy management and increase efficiency. Therefore, gas metering covers a wide range of technical areas, including both mechanical and electronic engineering. Several different gas meter designs are widely used depending on the volumetric flow rate of the gas to be measured, the predicted flow range, the type of gas being measured and other factors.
[0007] In the patent document numbered KR100434228B1, a solution is mentioned for measuring the disk movement with the sensor and reflecting it on the LCD screen as a result of the gas moving the disk with the shafts.
[0008] In the patent document numbered KR101924426B1, it is mentioned that as a result of the gas moving the diaphragm back and forth, the rotational force of the rotary sliders and gears is reflected on the digital screen with the help of the sensor.
[0009] In the Patent document numbered KR20040105386A, it is mentioned that the pressure sensor attached to the gas flow pipe is operated with a magnet attached to the rotating plate to measure the gas flow and the sensor reflects the calculated flow rates on the LCD screen.
[0010] In the Patent document numbered JP2018021849A, it is mentioned that the displacement of the diaphragm with gas pressure, the rotary disk (rotor) is activated by the wing shafts making oscillating movements, and with the addition of a magnet placed on it with a base and a magnetic sensor placed facing the magnet, the centrifugal force is created by the rotational movement of the rotor and the separation of foreign materials is ensured.
[0011] When the existing works in the art were examined, the need for a gas meter that includes a sensor and a numerator with an LCD screen connected to this sensor to reduce the cost by eliminating the rotary joint gear, axle gear assembly, magnetic coupling assembly and mechanical numerator gears and calibration gears and to provide the measurement during the rotation of the bakelite (rotating disk) was needed. Objects of the Invention
[0012] The object of the present invention is to reduce the cost by eliminating the rotary joint gear, axle gear assembly, magnetic coupling assembly and mechanical numerator gears and calibration gears, and to develop a gas meter comprising a sensor and a numerator with LCD display connected to this sensor to provide the measurement during the rotation of the bakelite (rotating disk).
[0013] Another object of the present invention is to improve financial savings and production simplification by eliminating the use of many mechanical gear assemblies and approximately 12 gears consisting of large and small calibration gears with different numbers of teeth.

[0037] A gas meter for measuring the volume of gas according to the invention essentially comprises
[0038] - a body (1),
[0039] - a meter cover (2) located on the body (1),
[0040] - an inlet fitting (3) through which gas is supplied to the meter,
[0041] - an outlet fitting (12) connected to the internal volume of the meter cover (2), through which gas is discharged from the meter,
[0042] - an inner body (5) connected to the inlet fitting (3), into which the gas is filled,
[0043] - two inlet chambers connected to the inlet fitting (3), two outlet chambers connected to the inlet chambers and the inner volume of the meter cover, located in the inner body (5),
[0044] - diaphragms between the inlet chambers and the outlet chambers, in different phases relative to each other, - lower joints that convert the movement performed by the diaphragms into an angular oscillatory movement due to the pressure difference between the respective chambers,
[0045] - upper joints (11), which convert the movement of the lower joints into a regular rotational movement,
[0046] - a disc (10) made of bakelite, rotated by the upper joints (11), having a channel allowing flow between the inlet and outlet chambers depending on its instantaneous angular position, and a gap (13) allowing flow between the outlet chambers and the inner volume of the meter cover (2),
[0047] - a sensor (8) facing the disk (10) and measuring the number of rotations of the disk (10) by detecting the change caused by the gas passage gap (13) into the inner body during the rotation of the disk (10).
[0048] The inventive gas meter may further comprise
[0049] - An electronic card with LCD display (6) connected to the LCD display number meter (4), which is an electronic component that converts the gas passage into numbers in cubic meters, showing the malfunctions and errors that may occur in the meter, error and warning messages, date and time information, the time of measurements, and total, instantaneous and timedependent consumption information and statistics in cubic meters, and can transfer data with components on the circuit board and communication modules such as Wi-Fi, RF, etc,
[0050] - a support (7) that allows the sensor (8) facing the disk (10) to remain stationary in the body (5),
[0051] - a numerator (4) with LCD display to which the sensor (8) is connected,
[0052] - cable (9) connecting the sensor (8) and LCD display numerator (4).
[0053] In the inventive gas meter, the gas coming from the inlet fitting (3) goes to the chambers in the inner body (5). The gas pressure difference in the chambers activates the diaphragm and the upper joints (11) connected to the diaphragm. The upper joints (11) give rotational motion to the disk (10) and cause the disk (10) to rotate. The sensor (8) located opposite the disk (10) measures the number of turns taken by the disk (10) with the help of the gap on the disk (10) and transmits the result to the electronic card (6) with LCD display on the LCD display numerator (4). The gas whose volume is measured is transferred to the usage area via the outlet fitting (12).
[0054] A gas meter according to the invention may also enable the measurement results to be displayed on an external display instead of on the LCD numerator (4). For this purpose, the relevant data can be transmitted to said external display by means of a cable (9) or a wireless device.
[0055] In the present invention, magnetic and mechanical gear assemblies are not used, which will provide production efficiency and financial gain.
