Biofouling is the unwanted buildup of microorganisms, plants, algae, or organisms such as barnacles and muscles on a wetted surface. When a LevelVent or AquaVent is deployed for an extended period of time, especially in a saltwater environment, there is the risk of biofouling. Biofouling on the pressure sensor can compromise the accuracy of the measurements.

A Solinst Biofoul Screen can be used to protect the LevelVent or AquaVent from biofouling. The copper-coiled Delrin screen naturally reduces biofouling, and lengthens the time a datalogger can be deployed before maintenance is required. The Biofoul Screen simply slips onto the sensor end of the logger where it is held in place with its compression fitting. It adds about 19 mm (3/4") to the length of the logger. It allows water to freely enter the pressure transducer inlets. It is replaced as required.
