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.Read More
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.

Yes. This system also supports Modbus, which is supported by most PLCs.
No. The unit has temperature compensation on it, but it is the temperature of the sensors that will be very different from the water temperature.
Yes. This bubbler supports the SDI-12 interface as a sensor or server, so any data logger that supports SDI-12 as a client will work.
The only item that requires regular maintenance is the desiccant. The interval that this needs servicing is based on the relative humidity of the site and how often the unit turns on the pump. Purging more often will draw air into the system, so that would shorten the time between visits to replace the desiccant.
Yes. The orifice can be installed in the well piping. Normally the orifice line is supported by a separate stainless-steel cable to prevent the orifice line from moving up or down, as this movement would show up in the data.
No. A stilling well is not needed. The orifice line is normally installed inside a two-inch conduit and secured in place, so there is no movement in the orifice line. It is best to install the outlet just above the sediment in the water to be measured. When the orifice line is securely installed, the unit makes accurate measurements of the water—even if the water has some movement, such as in a river. The measurement averaging time can also be increased to reduce the noise in the data, providing the same function that the stilling well does to average out the fluctuations of the water.
The LevelVUE™B10 does not log its own data and does require a data logger.
No. This is not a good data value for ambient air temperature. It is the temperature as seen by the internal pressure sensing element, and it will be affected by several other factors. For example, direct sunlight on an enclosure will heat it up much higher than ambient air temperature.
