Intelligent Level Sensor with PWM Output for Advanced Medium Detection and Process Monitoring

In modern industrial production, accurate liquid detection is no longer limited to simple level measurement. Many processes require intelligent identification of different media, phase separation monitoring, contamination detection, and reliable process protection.

F&V Intelligent Level Sensors are designed with advanced PWM (Pulse Width Modulation) output technology, enabling accurate detection and identification of different liquid media based on their dielectric characteristics.

By analyzing changes in the dielectric constant (DK value) of materials, the sensor can distinguish different liquids, detect media changes, and provide reliable signals for automated process control.

Unlike conventional level switches that only detect the presence or absence of liquid, F&V intelligent level sensors provide a smarter solution for complex industrial applications, including food and beverage processing, chemical production, water treatment, and industrial automation.

Advanced Medium Identification Based on Dielectric Constant Detection

Different liquids have different dielectric properties. F&V intelligent level sensors utilize changes in DK value to identify variations in media characteristics.

Through PWM output signals and professional calibration, the sensor can continuously monitor liquid conditions and recognize different materials within the same process system.

The sensor can be applied for:

Identifying different liquids flowing through pipelines
Detecting oil-water separation conditions
Monitoring product purity changes
Recognizing contamination between different media
Supporting automated process switching and control

For example, the sensor can distinguish between water, oil, milk, CIP cleaning solution, and other industrial liquids according to their dielectric characteristics.

Product Highlights

1. Medium Separation and Phase Separation Detection

During industrial processing, materials may exist in different phases, and these phases may need to be identified or ignored depending on the application requirements.

F&V intelligent level sensors can detect specific liquid phases and support accurate phase separation monitoring.

Typical applications include:

Detecting oil layers floating on water surfaces
Ignoring unwanted foam layers
Monitoring separation processes in tanks and vessels

This function helps improve process accuracy and ensures better control of production quality.

2. Reliable Level Detection in Tanks, Vessels, and Pipelines

Storage tanks, buffer tanks, and filling pipelines are commonly equipped with level sensors for liquid level monitoring.

With extremely fast response time, F&V intelligent level sensors provide accurate and reliable switching signals for automatic control systems.

The sensor helps industries achieve:

High and low-level monitoring
Overflow prevention
Filling process control
Automated production management

3. Early Detection of Medium Contamination

Detecting contamination at an early stage has significant economic and safety value, especially in food and beverage production.

F&V intelligent level sensors can identify changes in liquid characteristics and help detect unwanted substances during processing.

For example:

Detecting residual cleaning agents in liquid food processes
Monitoring product quality changes
Identifying contamination between different liquids

Early detection allows manufacturers to remove contaminated media before further processing, reducing production losses.

4. Pump Dry-Running Protection

Pumps are widely used in industrial production, and dry running can cause serious process problems, including inaccurate dosing, reduced efficiency, and equipment damage.

F&V intelligent level sensors provide reliable liquid presence monitoring, even in challenging conditions such as:

High-viscosity media
Crystallizing liquids
Complex process materials

By ensuring sufficient liquid supply, the sensor helps protect pumps and improve system reliability.
