The basic structure of an elliptical gear flowmeter is mainly composed of a flow transmitter and a counting mechanism. The following is a detailed introduction to the components of the elliptical gear flowmeter: Counter: The counter is an important part of the elliptical gear flowmeter, used to record and display the total amount of fluid flowing through it. It is usually associated with the number of rotations of an elliptical gear, and the fluid flow rate is determined by calculating the number of rotations of the gear. Transmitter: A transmitter (also known as a sensor) is used to convert flow signals into electrical signals or other forms of signals that can be transmitted. In this way, traffic information can be remotely monitored or recorded, facilitating automated control and data processing. Precision regulator (used for DN50 and above): The precision regulator is used to adjust the measurement accuracy of the flowmeter. In flow meters of DN50 and above, precision regulators can ensure that the flow meter can maintain high measurement accuracy under different operating conditions. Sealed coupling: Sealed couplings are used to connect different components of flow meters and ensure their sealing between them. This can prevent fluid leakage and ensure the normal operation of the flowmeter. Front and rear covers: The front and rear covers are located at the front and rear of the flowmeter, respectively, to protect the internal structure of the flowmeter. They are usually made of sturdy materials to ensure good performance even in harsh working environments. Cover plate: The cover plate is located on the upper or side of the flowmeter and is used to close the opening of the flowmeter. It usually works closely with other components of the flow meter to ensure that the fluid does not leak. Elliptical gear: Elliptical gear is the core component of elliptical gear flowmeter. It consists of two elliptical gears that mesh with each other, and when fluid passes through the flowmeter, it drives the gears to rotate. By measuring the number of rotations and rotational speed of the gear, the fluid flow rate can be calculated. The design of elliptical gears makes the flowmeter insensitive to changes in fluid viscosity, thereby improving measurement accuracy. Shell: The shell is the outer casing of an elliptical gear flowmeter, used to accommodate and protect all components of the flowmeter. It is usually made of sturdy and corrosion-resistant materials that have been ground to ensure that the flowmeter can maintain stable performance even in harsh working environments. The following is a schematic diagram of the internal structure of an elliptical gear flowmeter for a more intuitive understanding of its structure: In summary, the basic structure of an elliptical gear flowmeter includes a counter, transmitter, precision regulator (used for DN50 and above), sealed coupling, front cover, cover plate, elliptical gear, housing, and rear cover. These components work together to enable the elliptical gear flowmeter to accurately measure and record fluid flow.

2. Working principle of elliptical gear flowmeter

The flowmeter is composed of a measuring box and a pair of elliptical gears installed inside the measuring box, forming a sealed lunar cavity with upper and lower cover plates (not absolutely sealed due to the rotation of the gears) as the unit for calculating the primary displacement.
