The LevelVent 5 logger contains pressure and temperature sensors, a battery, memory for up to 150,000 data logs, and hydrophobic filter within a 22 mm x 173 mm (7/8" x 6.8") stainless steel housing with a corrosion-resistant coating.

The LevelVent uses a gauged pressure transducer; it is open to the atmosphere via a vented cable to the wellhead. The compact LevelVent wellhead is designed to fit in a Solinst 2" Well Cap Assembly, and provides easy connection for communication accessories.

The vented cable and Solinst LevelVent 5 logger are protected from moisture by permanent, built-in desiccants and hydrophobic filters in the logger and the wellhead.

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.

LevelVent 5 Applications

• Ideal for shallow deployment: up to 65 ft (20 m) submergence
• Aquifer characterization: pumping tests, slug tests, etc.
• Stream gauging, lake, reservoir and dam management
• Watershed, drainage basin and recharge monitoring
• Stormwater and runoff monitoring
• Water supply and tank level measurement
• Long-term water level monitoring in wells and surface water

Vented Datalogger Advantages
• Continuous, reliable water level data for longterm monitoring projects
• No barometric compensation required, saving data processing time
• Instant water level data for real-time aquifer test results

LevelVent 5 Programming & Communication

The LevelVent 5 is programmed and data downloaded using Solinst Levelogger Software and a PC Interface Cable. It can also be used with the Solinst Levelogger 5 App Interface and DataGrabber 5. Both accessories and PC Interface Cable conveniently connect directly to the LevelVent 5 wellhead.

Integrate the LevelVent 5 with Solinst Telemetry Systems, which use the latest wireless technologies. For deeper, hard to access applications, or areas that are prone to flooding, the Levelogger 5 Series of absolute pressure water level dataloggers are also options (see Model 3001 Levelogger 5 Series Data Sheet).

Integrate the LevelVent 5 with Solinst Telemetry Systems, which use the latest wireless technologies.

LevelVent 5 Vented Cable Options

LevelVent 5 vented cable assemblies are available in custom lengths of up to 500 feet.

Vented cables contain communication wires, as well as a vent tube running the length of the cable. Vented cables provide direct read communication from the LevelVent 5 logger to the wellhead. The vent tube and wires are jacketed in polyurethane, providing durability and protection.

The vented cables ar e easily and securely connected to the LevelVent 5 logger and wellhead, using stainless steel twist connections. A 2" Well Cap Assembly and hanger bracket are included to support the wellhead and vented cable when deployed.

Solinst Levelogger App & Levelogger 5 App Interface

The Levelogger 5 App Interface uses Bluetooth® technology to connect your LevelVent 5 to your smart device. With the Solinst Levelogger App, you can download data, view real-time data, and program your dataloggers (see Model 3001 Levelogger 5 App Interface data sheets).

DataGrabber 5

The DataGrabber 5 is a field-ready data transfer device that allows you to copy data from a LevelVent 5 onto a USB flash drive key, with one push-button. The DataGrabber 5 is compact and very easy to transport.
