Solinst announced the release of the LevelVent—a vented version of the company’s Levelogger water level and temperature data logger. The LevelVent shares many of the features that make the Levelogger a favorite for groundwater and surface water monitoring, but without the need for a barologger.

The LevelVent combines pressure and temperature sensors, a 10-year battery, and a data logger with FRAM memory for up to 120,000 data sets within small 7/8-inch x 7-inch stainless steel housing. It uses a gauged pressure transducer and is open to the atmosphere via a vented cable to surface. Custom-designed, durable vented cable assemblies are available up to 500 feet.

The LevelVent has a compact wellhead, which is designed to fit in a Solinst 2-inch well cap assembly for simple deployment. The wellhead connects easily to the vented cable, as well as directly to Solinst communication accessories such as the Levelogger app interface, DataGrabber, and PC interface cable.

The LevelVent is programmed using intuitive Solinst Levelogger software, which also contains options for downloading and viewing data, as well as real-time view, data compensation and diagnostic utilities. The LevelVent can be programmed in linear mode with sampling as fast as every 1/8th of a second, event-based mode, or with a user-defined schedule ideal for pumping and other aquifer characterization tests.

The LevelVent 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-percent and can withstand two times over-pressure without permanent damage. It features a robust, low-maintenance design.
