Can we help you?

When a Levelogger is deployed for extended periods, especially in coastal and saltwater environments, there is the risk of biofouling.

Biofouling on the pressure sensor or conductivity cell can compromise the reliability of the readings.

Leveloggers can be cleaned by soaking for a short time in a very weak acid solution, but this can be time consuming, increasing maintenance costs and trips to the field.

The Model 3001 Biofoul Screen for the Levelogger is an affordable option to lengthen the time a Levelogger Edge, Levelogger Junior Edge, or LTC Levelogger Junior can be deployed, before maintenance is required.

Using the natural anti-fouling characteristics of copper, the Biofoul Screen is designed to reduce the unwanted buildup of microorganisms, plants, algae, or organisms such as barnacles and mussels.

The Biofoul Screen consists of a Delrin sleeve wrapped with copper wire. The Biofoul Screen simply slips onto the sensor end of the Levelogger, where it is held in place by friction fit. The screen allows water to freely enter the pressure sensor of any Levelogger, and the conductivity cell of an LTC.

The Biofoul Screen improves the long-term performance of all Leveloggers, and helps ensure reliable conductivity and pressure measurements.
