Solinst - Model 3500 AquaVent 5 -Vented Water Level Datalogger
The AquaVent 5 uses the same vented pressure transducer and Vented Cable as the LevelVent 5; however, the batteries are user-replaceable 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.The AquaVent 5 Vented Water Level Datalogger records accurate water level and temperature measurements in shallow groundwater and surface water applications. It combines pressure and temperature sensors, hydrophobic filters and datalogger within a 22 mm x 173 mm (7/8" x 6.8") stainless steel housing with corrosion-resistant coating.
The AquaVent 5 uses a gauged pressure transducer; it is open to the atmosphere via a vented cable to surface. Atmospheric pressure is applied to the transducer diaphragm, providing a cancellation effect for barometric pressure. This results in actual water level recordings.
The vented cable and Solinst AquaVent 5 logger are protected from moisture by built-in desiccants and hydrophobic filters.
The vented pressure transducer is made of Hastelloy®, making it extremely durable and accurate in a wide range of temperature and monitoring conditions. The sensor provides an accuracy of 0.05% FS, and can withstand 2 times over-pressure without permanent damage.
The robust memory can hold up to 150,000 data sets when programmed in Solinst Levelogger® Software.
