Concepts of Technical and Operational Information:

• Equal Pressure: The equal-level filling machine operates by maintaining equal pressure in the liquid reservoir and the container being filled. This ensures that the liquid level in the container remains constant during the filling process, resulting in precise filling.
• Gravity and Vacuum: The equal-level filling machine uses gravity to fill the liquid reservoir and vacuum to control the flow of liquid into the container. The vacuum helps to prevent overfilling and spillage.
• Liquid Type: The equal-level filling machine can be used to fill various types of liquids, including thin liquids such as water and thick liquids such as syrup.

Mechanical Structure:

• Liquid Reservoir: The liquid reservoir is where the liquid to be filled is stored. The reservoir is equipped with sensors that monitor the liquid level and control the flow of liquid into the container.
• Filling Nozzle: The filling nozzle is where the liquid flows out of the reservoir and into the container. The nozzle is designed to maintain equal pressure in the reservoir and the container to ensure precise filling.
• Conveyor System: The conveyor system is used to transport the containers through the filling process. The speed of the conveyor can be adjusted to accommodate different production rates.
• Control Panel: The control panel is used to monitor and adjust the filling process. The panel displays the liquid level in the reservoir and allows the operator to adjust the flow rate of the liquid.

In conclusion, the equal-level filling machine is a versatile and efficient liquid filling machine that is commonly used in the food, beverage, and pharmaceutical industries. Its key features include precise filling, versatility, high speed, and ease of use. The machine operates by maintaining equal pressure in the liquid reservoir and the container being filled, using gravity and vacuum to control the flow of liquid, and can be used to fill various types of liquids. Its mechanical structure includes a liquid reservoir, filling nozzle, conveyor system, and control panel.

Equal-level filling and volumetric filling are two different concepts.

Equal-level filling refers to filling containers to the same liquid level regardless of their individual volumes. This is achieved by using a liquid level sensor and adjusting the fill volume for each container to ensure the liquid level is consistent.

Volumetric filling, on the other hand, refers to filling containers with a fixed volume of liquid. This is typically achieved using a piston or a rotary valve to dispense a precise amount of liquid into each container.

The key features of an equal-level filling machine include a liquid level sensor, programmable fill settings, and a control system to adjust the fill volume for each container. The machine should also be capable of handling a variety of container sizes and types.

The mechanical structure of an equal-level filling machine typically includes a liquid reservoir, a delivery system (such as a pump), and a fill nozzle. The fill nozzle is designed to be adjustable to accommodate different container sizes and shapes. The liquid level sensor is typically located near the fill nozzle.

To ensure the accuracy of the fill volume, the machine must be calibrated regularly. This involves measuring the actual liquid level in a sample of filled containers and adjusting the fill settings as necessary.

Overall, an equal-level filling machine is a reliable and efficient way to fill containers with consistent liquid levels.

Volumetric filling, also known as which is different to the volumetric filling, is a process of filling containers with a fixed volume of liquid. On the contary, the procss of equal-level filling is not based on volume. 

The process involves several steps to ensure accurate and consistent filling:

Container positioning: The containers are placed on the conveyor system and aligned to ensure they are positioned correctly for filling.

Filling nozzles: The filling nozzles are designed to accurately dispense the required volume of liquid into the containers. The number of filling nozzles can vary depending on the speed and volume of production.

Liquid supply: The liquid supply is maintained at a constant level and is fed to the filling nozzles through a series of pipes and valves.

Control system: The filling machine is equipped with a control system that ensures accurate and consistent filling by controlling the flow of liquid to the filling nozzles.

Leveling: The containers are leveled during the filling process to ensure an equal level of liquid in each container.

Capping: Once the containers are filled, they are moved to the capping station where caps are applied to the containers.

The key features of an equal-level filling machine include the ability to accurately dispense a fixed volume of liquid, the use of multiple filling nozzles for high-speed production, and a control system that ensures consistent filling. The mechanical structure of the machine consists of a conveyor system, filling nozzles, liquid supply system, control system, leveling mechanism, and capping station. The dimensions and specifications of each component can vary depending on the specific needs of the production line.

There is another type of mechanical equal-level filling method. In this method, the liquid is filled to a constant level by using a float valve. The float valve is designed to maintain the same level of liquid in the container by opening and closing a valve based on the liquid level.

The equal-level filling machine works by using a series of float valves that are attached to a central reservoir of liquid. Each float valve is connected to a separate filling nozzle that fills a container to a constant level. As the liquid is dispensed from the central reservoir, the float valve opens to allow more liquid to enter the container until the liquid reaches the desired level.

The key features of an equal-level filling machine include the use of float valves to maintain a consistent liquid level, the ability to fill containers of different sizes and shapes, and the option to control the speed of the filling process. This type of filling machine is commonly used in the food and beverage industry, as well as in the pharmaceutical and cosmetic industries.

The mechanical structure of an equal-level filling machine typically consists of a central reservoir that holds the liquid, a series of float valves that are connected to filling nozzles, and a control system that regulates the flow of liquid to the filling nozzles. The filling nozzles can be adjusted to accommodate different container sizes and shapes, and the control system can be programmed to adjust the filling speed based on the specific needs of the application.

Overall, the equal-level filling machine provides a reliable and consistent filling solution for a variety of industries. Its use of float valves and precise control system ensures that each container is filled to the same level, reducing waste and improving efficiency.

Another mechanical equal-lenvel filling method is based on air pressure. The liquid is filled into the container from a filling nozzle until the liquid level reaches the nozzle tip. The air inside the container is then expelled through a separate channel in the filling nozzle, and as the liquid level rises, the air is pushed out of the container. The filling process stops automatically when the liquid level reaches the nozzle tip and the pressure inside the container becomes equal to the atmospheric pressure.

This method is commonly used for filling containers with low viscosity liquids such as water or other beverages, where the liquid can flow easily and the liquid level can be easily controlled. The main advantage of this method is that it ensures a consistent fill level across all containers, which is important for aesthetic and practical reasons.

However, this method may not be suitable for filling high viscosity liquids or liquids that contain particulates or bubbles, as these can cause variations in the liquid level and make it more difficult to control. Additionally, the equal-level filling method may not be as accurate as other filling methods, such as volumetric or weight-based filling, which can measure the exact amount of liquid being filled into each container.
