solinst 3250 levelvent 6 vented water level dataloggers

Model 3250 LevelVent 6

Real-Time Water Level Data. Zero Barometric Processing.

Get instantaneous, accurate water level measurements without post-processing barometric compensation. The Model 3250 LevelVent 6 combines a Hastelloy® gauged pressure sensor (0.05% FS accuacy), permanent built-in desiccants, and a 10-year battery into a rugged vented logger built for shallow groundwater and surface water monitoring.

  • Instant Water Levels — No Compensation Needed:
    Uses a gauged pressure transducer open to the atmosphere via a vented cable. Delivers direct water level readings immediately without requiring a separate Barologger or post-processing data compensation wizards.
  • Superior Moisture Protection & Maintenance-Free Design:
    Features permanent, built-in hydrophobic filters and desiccants inside both the logger body and the compact wellhead. Eliminates the hassle and expense of replacing external desiccant tubes in the field.
  • Hastelloy® Transducer & Faraday Surge Protection:
    Precision Hastelloy® sensor delivers 0.05 FS accuracy with 2 times over-pressure protection. An integrated Faraday cage design protects internal electronics against power surges and lightning spikes.
  • 2X Fast Downloads & Smart USB-C Connectivity:
    High-speed communication up to 38.4k Baud via the Mk3 USB-C PC Interface Cable directly at the wellhead. Seamlessly update firmware and run automated cable diagnostics in the field.

The LevelVent 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 is the right choice for your water level monitoring application.

Engineered for Shallow Deployments & Aquifer Characterization

When conducting short-term pumping tests or monitoring dynamic surface water fluctuations, waiting to perform barometric post-processing delays decision-making. The LevelVent 6 gives you immediate, high-accuracy water head data right at the wellhead.

  • Gauged Piezoresistive Silicon Sensor: Constructed with a Hastelloy® sensor element for outstanding stability across temperature fluctuations (0˚C to 50˚C compensation range).

  • Rugged Polyurethane Vented Cables: Custom cable lengths up to 1500 ft (450 m) featuring polyurethane jacketing, stranded stainless steel non-stretch strength members, and a vented tube for atmospheric pressure equalization.

  • 10-Year Battery & Zero-Data-Loss Backup: Powered by an internal lithium battery engineered for up to a decade of continuous service. Stores up to 150,000 readings in primary memory plus 20,000 dedicated backup readings.

  • Compact Wellhead Assembly: Snugly mounts inside standard Solinst 2 inch Well Cap Assemblies 30 mm x 76 mm (1.2 inches x 3.0 inches), providing IP64 dust and splash protection for surface communication.

The Importance of Measuring Drawdown

How Using a Levelogger and 101D Water Level DrawDown Meter Together Provides Essential Data What is Drawdown? Drawdown is a change in groundwater level due to an applied stress, caused by events such as: Pumping from a well Pumping from a neighbouring well Intensive water taking from local area Seasonal declines as recharge rates lower How is Drawdown Measured?
