Specifications
Model 3250 LevelVent 5 Water Level Datalogger
The Solinst LevelVent 5 is a vented version of our popular Levelogger®. The highly accurate datalogger is designed to record water level and temperature measurements during shallow groundwater and surface water deployments.
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.
