Solinst 3250 LevelVent 5

The LevelVent 5 records very accurate water level and temperature measurements in shallow groundwater and surface water applications. The loggers combine pressure and temperature sensors, datalogger, and memory for up to 150,000 data logs within a 22 mm x 173 mm (7/8” x 6.8”) stainless steel housing with corrosion-resistant coating. The LevelVent 5 logger also contains a 10-year lithium battery (based on 1 reading per minute).

The LevelVent 5 use a vented pressure sensor; it is open to the atmosphere via a vent tube to surface. This applies atmospheric pressure to the sensor, resulting in water level readings that are automatically compensated for barometric effects

The loggers use the same durable Hastelloy pressure sensor as the Levelogger 5, providing 0.05% FS accuracy. It can operate in temperatures from -20ºC to 80ºC (0ºC to 50ºC is the temperature compensation range).

The LevelVent 5 come in different pressure ranges to suit expected water level fluctuations, from 5 to 20 m (15 to 65 ft.). Vented Cables are available in lengths to 500 ft. The Vented Cable and loggers are protected from moisture by built-in desiccants and hydrophobic filters.

When programmed using Levelogger Software, the LevelVent 5 can be set to record as often as every 1/8 of a second. There are linear, event-based, and scheduled sampling mode options. They are also compatible with the Solinst Levelogger 5 App Interface, Solinst Readout Unit (SRU) and DataGrabber 5.

The LevelVent 5 Wellhead is compact and seats inside a Solinst 2″ Well Cap Assembly. It provides an easy connection for communication accessories. The LevelVent 5 Wellhead connects to Solinst Levelogger PC Software using a USB PC Interface Cable. The Levelogger 5 App Interface, SRU and DataGrabber 5 connect directly to the LevelVent 5 Wellhead.
