Robust Sensor

Streamlined Design

Minimal Sensor Fouling

Oil-filled Submerged AV sensor models are great solution for monitoring sites that are susceptible to fouling of the pressure transducer. The cavity is filled with high-viscosity silicon oil to reduce the collection of sand, silt and grit on the pressure transducer. Use the non-oil-filled cover plate model in sites where the pipe could run dry. Either way, we’ve thought about the little details that will reduce your maintenance or lost data hassles.
