The Solinst LevelVent is a vented version of our popular Levelogger®. The highlyaccurate datalogger is designed to record water level and temperature measurements during shallow groundwater and surface water deployments.

The LevelVent logger contains pressure and temperature sensors, a battery, FRAM memory for up to 120,000 data logs*, and hydrophobic filter within a 7/8" x 7" (22 mm x 178 mm) stainless steel housing.

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 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 Programming & Communication
The LevelVent is programmed and data downloaded using Solinst Levelogger Software and a USB PC Interface Cable. It can also be used with the Solinst Levelogger App and Interface, and DataGrabber. Both accessories and PC Interface Cable conveniently connect directly to the LevelVent wellhead. For deeper, hard to access applications, or areas that are prone to flooding, the Levelogger Series of absolute pressure water level dataloggers are also options (see Model 3001 Levelogger Edge Data Sheet).  

LevelVent Vented Cable Options
LevelVent 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 logger to the wellhead. The vent tube and wires are jacketed in polyurethane, providing durability and protection. The vented cables are easily and securely connected to the LevelVent 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.
