What is a Liquid Level Sensor?
A liquid level sensor is an instrument used to detect and measure the height or volume of liquid in a tank or container. These sensors are indispensable for industrial processes that demand precise monitoring to prevent overflows, leaks, or equipment damage.
Liquid level sensors provide real-time data that enable operators to make quick decisions, ensuring operational efficiency and safety. Industries like food and beverage, water treatment, and chemical manufacturing heavily rely on these devices to comply with safety regulations and maintain process consistency.
Icon Process Controls specializes in manufacturing liquid level sensors that are highly accurate, durable, and versatile, making them a preferred choice for industrial applications.
Types of Liquid Level Sensors by Icon Process Controls
Icon Process Controls offers various types of liquid level sensors tailored to meet specific requirements. Below is a detailed breakdown of the four most popular types: radar, submersible, ultrasonic, and float sensors.
1. Radar Liquid Level Sensors
ProScan 3 • ProScan 2 • ProScan • MLR-70 Guided Wave
How They Work
Radar level sensors operate by emitting microwave signals toward the liquid surface. These signals bounce back to the sensor, which calculates the liquid level based on the travel time of the reflected waves. This method provides fast and highly accurate measurements.
Advantages
- Non-Contact Operation: Radar sensors do not touch the liquid, making them ideal for hazardous, corrosive, or high-temperature applications.
- Environmental Resilience: These sensors perform reliably in extreme conditions, including high temperatures, pressures, or dusty and vapor-filled environments.
- Consistent Accuracy: Radar sensors maintain precision even in challenging conditions, ensuring reliable performance in demanding applications.
Applications
Radar sensors are commonly used in industries such as oil and gas, chemical processing, and food manufacturing, where contamination control is critical. They are also extensively used in water storage and wastewater treatment facilities.
User Insights
Operators appreciate the durability and low maintenance requirements of Icon’s radar sensors. Many users highlight their reliability in environments where precision is critical.
2. Submersible Liquid Level Sensors
100 Series • 200C Series • 300S Series • TankPro
How They Work
Submersible sensors are immersed directly into the liquid. They measure hydrostatic pressure, which is proportional to the liquid depth, and convert this pressure into accurate level readings.
Advantages
- Ideal for Depth Monitoring: Submersible sensors excel in applications requiring measurement at significant depths, such as deep wells or large tanks.
- Rugged Construction: Built with corrosion-resistant materials, these sensors handle continuous exposure to liquids without compromising performance.
- Continuous Monitoring: Submersible sensors are designed for round-the-clock operation, ensuring consistent performance in demanding environments.
Applications
These sensors are widely used in water and wastewater management, environmental monitoring, and deep reservoirs.
User Insights
Operators in water treatment facilities value the robust construction and accuracy of Icon’s submersible sensors. These sensors deliver dependable data even in challenging environments.
3. Ultrasonic Liquid Level Sensors
How They Work
Ultrasonic sensors emit high-frequency sound waves toward the liquid surface. The sensor measures the time it takes for the sound waves to reflect back, calculating the liquid level based on the speed of sound in the air.
Advantages
- Non-Contact Design: These sensors avoid contamination by not touching the liquid, making them perfect for hygienic applications.
- Versatile Performance: Ultrasonic sensors function across various environmental conditions and are straightforward to install and maintain.
- Low Maintenance: The lack of moving parts reduces the need for regular upkeep, ensuring cost-effective operation.
Applications
Ultrasonic sensors are commonly employed in industries such as chemical storage, food processing, and wastewater management, where cleanliness and accuracy are paramount.
User Insights
Users praise Icon’s ultrasonic sensors for their simplicity and reliability. They also appreciate the non-contact design, which ensures consistent readings without frequent adjustments.
4. Float Level Sensors & Switches
CFL Float Liquid Level Sensor • PLF • PLS • FloatPro
How They Work
Float level switches use a buoyant float that rises and falls with the liquid level. When the float reaches a specific point, it activates a switch that signals the control system.
Advantages
- Affordable Solution: Float switches are cost-effective, making them ideal for basic high or low-level detection needs.
- Reliable and Simple: With minimal moving parts, these sensors are easy to install and maintain.
- Effective for Basic Applications: While not as precise as other sensors, they provide reliable level detection in straightforward applications.
Applications
Float switches are frequently used in open tanks, sumps, and reservoirs, especially in water treatment, mining, and manufacturing industries.
User Insights
Operators appreciate the simplicity and dependability of Icon’s float level switches. Users often cite their affordability and effectiveness in delivering consistent performance for basic applications.
