The Bubbler System: A Reliable Solution for Level Measurement in Environmental & Water Treatment

The bubbler system, a tried and true technology in environmental and water treatment, provides a robust and accurate method for measuring liquid levels. Its operation is based on the principle of pressure differential, making it highly suitable for various applications where traditional methods like float switches or ultrasonic sensors may fall short.

How it Works:

The bubbler system utilizes compressed air to create a constant stream of bubbles through a submerged tube. This air stream displaces the liquid, generating a pressure proportional to the depth of the liquid. The pressure difference between the air supply and the bubbler tip is measured by a differential pressure transmitter, which provides an accurate reading of the liquid level.

Advantages of Bubbler Systems:

• High Accuracy and Reliability: Bubbler systems are known for their accuracy and reliability, even in harsh environments. They are unaffected by foam, suspended solids, and variations in liquid density.
• Versatility: Bubbler systems can measure levels in tanks, ponds, reservoirs, and other liquid containers, regardless of their size or shape. They are also suitable for measuring levels in liquids containing high concentrations of solids or suspended matter.
• Low Maintenance: Bubbler systems require minimal maintenance. The submerged tube is typically made of durable materials, and the air supply requires minimal upkeep.
• Cost-Effectiveness: Although the initial installation cost may be higher than some other level measurement methods, bubbler systems offer long-term cost savings due to their reliability and low maintenance requirements.

Applications in Environmental & Water Treatment:

Bubbler systems find widespread use in various environmental and water treatment applications, including:

• Wastewater Treatment: Measuring levels in aeration tanks, clarifiers, digesters, and sludge holding tanks.
• Drinking Water Treatment: Monitoring levels in reservoirs, clearwells, and filtration tanks.
• Process Control: Controlling the flow of liquids, automating the addition of chemicals, and monitoring levels in various industrial processes.

Common Terminology for Pneumatic-Type Differential Level Controller:

Pneumatic Differential Level Controller: A device that measures the level of a liquid by creating a differential pressure between the air supply and the bubbler tip.

Differential Pressure Transmitter: A sensor that measures the pressure difference between the air supply and the bubbler tip.

Bubbler Tube: A submerged tube that introduces compressed air into the liquid.

Air Supply: A source of compressed air that provides the constant flow of bubbles.

Calibration: The process of adjusting the differential pressure transmitter to ensure accurate level readings.

Conclusion:

The bubbler system offers a robust, accurate, and reliable solution for level measurement in environmental and water treatment applications. Its versatility, low maintenance requirements, and cost-effectiveness make it a popular choice for various industries. Understanding the working principle and common terminology associated with bubbler systems allows engineers and operators to effectively utilize this technology for optimal process control and environmental monitoring.
