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.
Features
- Gauged pressure sensor for highly-accurate water level measurements: 0.05% FS
- Multiple built-in hydrophobic filters and desiccants — no need to replace, reduces maintenance
- Easy-to-access, user-replaceable batteries in Wellhead
- Options for MODBUS (RS-232/RS-485) and SDI-12
- Separate cables for each communication protocol
- Corrosion and abrasion-resistant coating baked-on using polymerization technology
Applications
- Ideal for shallow applications: up to 65 ft (20 m) submergence
- Aquifer characterization: pumping tests, slug tests, etc
- Stream gauging, lake and reservoir management
- Watershed, drainage basin and recharge monitoring
- Stormwater and runoff monitoring
- Long-term water level monitoring in wells and surface water
AquaVent Benefits
- Automatic barometric compensation reduces time required for post data processing
- Integrate into a third-party data collection system for remote real-time data
- Continuous, reliable water level data for long-term monitoring projects
- Actual water level readings for instant aquifer test results

Communication Options
The AquaVent has options for communicating strictly with Solinst software and accessories, or integrating into a telemetry system, SCADA/PLC system or a third-party datalogger.
The AquaVent can communicate with Levelogger Software. It can be used with the Solinst Levelogger App and Interface, and the DataGrabber™.
AquaVent Communication Wellhead
The AquaVent Communication Wellhead fits conveniently onto a 2" (50 mm) well casing using the well cap base (a 4" well adaptor is available).
There are two options: the SP Wellhead has a connection for communicating with Solinst software and accessories; the SPX Wellhead has an additional connection for communicating with third party dataloggers or telemetry systems using MODBUS (RS-232/RS-485) or SDI-12 protocols.
Each Wellhead contains 4 1.5V AA lithium batteries that power the AquaVent logger. They are user-replaceable and can last 8 years based on 1 reading per minute (the internal AquaVent logger battery is only used to maintain the clock).
For permanent moisture protection, the Wellheads contain multiple built-in desiccants and have a hydrophobic filter where the vented cable terminates at surface.
SP Wellhead
One 10-Pin Connection for Solinst Software and Accessory Connector Cables
SPX Wellhead
Additional 12-Pin Connection for SDI-12 and MODBUS RS-232 and RS-485 Connector Cables
