The AquaVent 5 uses the same vented pressure transducer and Vented Cable as the LevelVent 5; however, the batteries are userreplaceable and located in the AquaVent 5 Wellhead at surface. The AquaVent 5 Wellhead provides options to communicate with Solinst Levelogger Software and accessories as well as third party equipment using SDI-12 or MODBUS protocols. The Wellhead fits conveniently onto a 50 mm (2") well casing. Permanent desiccants and hydrophobic filters protect the AquaVent 5 from moisture.
