Levelogger Biofoul Screen Instructions
Operating Principles
When a Solinst water level datalogger is deployed for an extended period of time, especially in coastal and seawater enviornments, there is the risk of biofouling on the Pressure Sensor and Conductivity Cell, which can affect the reliability of the measurements.
Biofoul Screen (#110659)
The Biofoul Screen can be used with the Levelogger 5, Levelogger 5 Junior, Levelogger 5 LTC, LevelVent 5, AquaVent 5, as well as previous Solinst datalogger versions.

Using the Biofoul Screen
- Loosen the Retaining Nut on the Biofoul Screen Body.
- Slide the datalogger into the Biofoul Screen Body, sensor end first, until it seats in the end of the Body.
Note:
The Biofoul Screen is designed to allow water to flow freely through the Screen and the Conductivity Cell, as well as to the Pressure Sensor inlet.
- It is recommended to line-up the Conductivity Cell with the opening in the Biofoul Screen Body (if installing on a Levelogger 5 LTC).
- Hand tighten the Retaining Nut onto the body of the datalogger. Do not over tighten.
- Replace the Biofoul Screen as required.
When installed, the Biofoul Screen adds approximately 3/4″ (19 mm) to the length of the datalogger.

How Using a Levelogger and 101D Water Level DrawDown Meter Together Provides Essential Data What is Drawdown? Drawdown is a change in groundwater level due to an applied stress, caused by events such as: Pumping from a well Pumping from a neighbouring well Intensive water taking from local area Seasonal declines as recharge rates lower How is Drawdown Measured?
