Overview
The LevelVue™B10 is a cost-effective, accurate, reliable solution for water-level measurements based on a non-submersible pressure transducer system. This type of sensor is a bubbler. Bubblers accurately measure the pressure it takes to create a continuous airflow in an airline submerged in water. The LevelVue B10 is designed for ease of use while providing long-term performance and accuracy. With a built-in keypad and display, you can complete your setup and site visit tasks using the LevelVue B10. The LevelVue B10 interfaces with data loggers or other controllers using SDI-12 or Modbus.

Detailed Description
The LevelVue B10 bubbler incorporates all the components needed to be a self-contained, pressurized air-supply system. This bubbler has an industrial air compressor (-40° to +80°C), large air tank (0.8 L), and other components that replace the need for pressurized air tanks and manual valves found in the older continuous gas flow systems. The LevelVue B10 meters the airflow to create a constant flow in the orifice line regardless of the water depth above the outlet. Precision sensors monitor the tank pressure and the line pressure to consistently maintain the same airflow. The precision sensor monitoring the pressure on the orifice line precisely detects the pressure required to push air through the line. This pressure value is directly related to water depth. Applying a simple conversion to the pressure value creates the value of water depth in feet, meters, or other units of measure.
