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.
Why the Solinst LevelVent 5 is a Great Choice:
- Vented version of our popular Levelogger®
- Accurate (0.05%FS) water level data
- 10 year battery based on 1 reading per minute
- No desiccants to replace
- Extremely durable vented cable (up to 500ft length)
- Custom blowout fitting for easy vented cable maintenance
- Complete compatibility with Levelogger accessories and Solinst telemetry systems
The LevelVent 5 is designed to provide instantly accurate water level data, without the need for barometric compensation. If you need true water level data right on site, without running any data compensation routines, the LevelVent 5 is the right choice for your water level monitoring application.
Where to Use the LevelVent 5:
- Ideal for deployments to 500 ft, with up to 65 ft submergence
- Excellent for aquifer characterization: pumping tests, slug tests, and more
- Stream gauging, lake monitoring, reservoir and dam management installations
- Watershed, drainage basin and groundwater recharge monitoring
- Gauged water level sensor is suited to stormwater event and runoff monitoring where rapid readings are typically required
- Water supply and tank level measurement
- Long-term water level monitoring in wells and surface water
Features
