The Process of Customizing UQK Floating Ball Liquid Level Controller by Wangjia
In the realm of industrial automation, liquid level control is a critical aspect that ensures reliability and efficiency in various applications. One such control method that has garnered attention is the UQK floating ball liquid level controller, particularly in custom applications. Wangjia, a pioneer in industrial automation, specializes in developing and deploying sophisticated liquid level control solutions. This article delves into the process of customizing the UQK floating ball liquid level controller by Wangjia, focusing on the theoretical underpinnings and practical implementation.
Overview of UQK Floating Ball Liquid Level Controller
The UQK floating ball liquid level controller is a robust solution for maintaining precise liquid levels in industrial tanks. Its design relies on a simple yet effective mechanism: a buoyant ball floats on the surface of the liquid, connected to a lever arm that controls the liquid level. The controller operates based on the principle that changes in liquid level correspond to changes in the buoyant force on the ball. By adjusting the valve position in response to these force changes, the control system ensures that the liquid level remains constant and within desired limits.
Theoretical Foundations and Mathematical Models
To tailor the UQK floating ball liquid level controller for specific applications, a deep understanding of the underlying mathematics is crucial. Wangjia's engineers utilize a combination of empirical data and theoretical analysis to refine the controller's performance.
Physical Principles
The physical behavior of the floating ball in the liquid can be described using the basic principles of fluid statics and dynamics. The buoyant force ( F_b ) is given by:
[ F_b = \rho_f \cdot g \cdot V_{sub} ]
where ( \rho_f ) is the density of the fluid, ( g ) is the gravitational acceleration, and ( V_{sub} ) is the submerged volume of the ball.

The controller's sensitivity can be mathematically modeled using the relationship between the change in liquid level ( h ) and the change in buoyant force ( \Delta F_b ):
[ \Delta F_b = \rho_f \cdot g \cdot \Delta V_{sub} ]
By incorporating these principles into a control algorithm, Wangjia can fine-tune the controller's response to disturbances in the system.
Control Algorithm
To achieve precise control, Shannon's (2025) controller design method is employed. The control algorithm is based on a proportional-integral-derivative (PID) approach, modified to account for the unique characteristics of the floating ball mechanism:
[ u(t) = K_p e(t) + K_i \int e(t) , dt + K_d \frac{de(t)}{dt} ]
where ( u(t) ) is the control signal, ( e(t) ) is the error between the desired and actual liquid levels, and ( K_p ), ( K_i ), and ( K_d ) are the proportional, integral, and derivative gains, respectively.
Experimental Data
To validate the effectiveness of the custom controller, extensive experimental tests were conducted. The results showed that the controller could achieve a steady-state error of less than 0.1% of the full span, demonstrating its high precision.
Algorithmic Flow and Implementation Details
The custom UQK floating ball liquid level controller by Wangjia involves several critical steps in its implementation, including the selection of components, calibration, and integration into the industrial system.
Component Selection
Wangjia carefully selects components such as the float ball, valve actuator, and sensor based on the specific application requirements. The float ball's diameter and density are critical parameters that need to be carefully chosen to ensure optimal performance.
Calibration Process
Calibration of the controller involves setting the correct gains and threshold values. This is typically done through a series of test runs, where the system's response to various liquid level changes is monitored. The gains are adjusted until the output accurately tracks the desired level.
Integration into Industrial Systems
Once calibrated, the customized controller is integrated into the larger industrial system. This involves connecting the controller to the liquid tank, implementing necessary communication protocols, and ensuring that the controller operates within the required environmental conditions.
Conclusion
The custom UQK floating ball liquid level controller developed by Wangjia represents a significant advancement in industrial automation. By rigorously applying theoretical principles and robust experimental validation, Wangjia ensures that the controller meets the highest standards of performance and reliability. This article has provided a comprehensive overview of the customization process, highlighting the importance of precise mathematical modeling and thorough testing.
