Level control systems are critical automation solutions that ensure liquid, solid, or granular materials are maintained at a specific level in industrial facilities. Accurate and continuous control of material levels in tanks, silos, reactors, and vessels is vital for both product quality and process safety. In systems where level control is not properly implemented, overflow, dry running, incorrect dosing, and serious safety risks may occur.

In today’s industry, production processes have become increasingly complex, tolerances have narrowed, and quality expectations have risen. Under these conditions, manual level control methods are insufficient for sustainable and safe production. Level control systems continuously monitor processes and automate intervention through sensors, control equipment, and automation software.

As Körfeztek Teknoloji, we consider level control systems not merely as measurement or alarm solutions, but as integrated automation solutions that ensure process stability, increase production efficiency, and support plant safety. By integrating mechanical infrastructure, sensor technologies, automation, software, and data management, we provide customized, reliable, and sustainable level control solutions for industrial facilities.

What Is Level Control?
Level control is the control process that ensures material contained in tanks, silos, boilers, or similar open or closed vessels is maintained within a defined minimum and maximum level range. In this process, the level is measured, evaluated, and automatic intervention is carried out when necessary.

Level control systems perform the following main functions:

Continuous monitoring of material level
Prevention of overflow or emptying risks
Ensuring process continuity
Maintaining safety and quality standards

The Importance of Level Control Systems in Industry
Level control forms the foundation of many industrial processes. Incorrect level control can lead to production stoppages, equipment damage, and environmental risks.

The main advantages provided by level control systems include:

Increased process safety
Preservation of product quality
Prevention of overflow and dry-running risks
Reduction of energy and raw material losses
Reduced operator dependency
Automated and traceable production

These advantages make level control systems indispensable in industries such as chemicals, food, pharmaceuticals, energy, water treatment, petrochemicals, and metallurgy.

Application Areas of Level Control Systems
Level control systems are used in a wide range of industrial applications.

Main application areas include:

Liquid storage tanks
Chemical reactors
Food and beverage production lines
Water and wastewater treatment plants
Silos and bunker systems
Boilers and steam systems
Energy and petrochemical plants

Each application must be specifically designed according to process conditions and safety requirements.

Level Measurement Methods
Accurate and reliable level measurement is the foundation of level control systems. The measurement method is selected based on material type, temperature, pressure, and environmental conditions.

Float Level Measurement
A simple and economical method, typically preferred for clean liquids.

Capacitive Level Sensors
Widely used for both liquid and solid materials, providing contact measurement.

Ultrasonic Level Sensors
Provide non-contact measurement and are commonly used in open tanks and silos.

Radar Level Measurement Systems
Suitable for high-precision and harsh process conditions, minimally affected by steam, temperature, and pressure.

Pressure Transmitters
Calculate liquid level based on hydrostatic pressure and are preferred for deep tanks.

Main Components of Level Control Systems
For a level control system to operate reliably, components must be correctly selected and integrated.

Level Sensors
Measurement devices that detect material level.

Control Unit
PLCs or control relays manage the system based on level information.

Actuators
Pumps, valves, or motors provide level control.

Alarm and Warning Systems
Inform operators in minimum or maximum level situations.

Software and Monitoring Systems
Level data is recorded, reported, and analyzed.

Automation and PLC Integration
Modern level control systems operate integrated with PLC and automation infrastructures. This integration allows level control to be performed automatically without manual intervention.

This structure provides:

Precise and fast level control
Synchronized process operation
Remote monitoring and intervention
Simplified fault and alarm management

Safety and Protection in Level Control
Level control systems play a critical safety role, especially in processes involving hazardous and flammable materials. Overflow or emptying situations can pose serious risks.

For this reason, safety is enhanced through:

Redundant sensors
Safety relays
Dual-channel measurement systems
Emergency shutdown scenarios

Quality and Process Stability
Proper level control is one of the fundamental requirements for process stability. Fluctuating levels can cause inconsistencies in product quality.

With level control systems:

Homogeneous production is ensured
Dosing errors are prevented
Standard product quality is maintained

Energy and Cost Efficiency
Level control systems optimize energy and raw material usage by preventing unnecessary pump operation and material losses.

This results in:

Reduced energy consumption
Extended equipment lifespan
Lower operating costs

Flexible and Modular Level Control Solutions
Flexibility is essential in facilities with high product variety and process variability. Modular level control systems can be easily adapted to different tanks and processes.

This enables:

Rapid commissioning of new processes
Easy management of capacity increases
Optimized investment costs
