The Solinst Model 3250 LevelVent 5 is a vented version of the 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.

As the Levelogger App Interface will not connect directly to the top of a Solinst datalogger, it is necessary to have connection accessories. With the Levelogger or Rainlogger, one of the following accessories is required:
Leveloggers. Provides detailed information on the datalogger,
and includes options for running a self-test, doing a memory
dump and creating/emailing reports.
