The Solinst AquaVent records accurate water level and temperature measurements in shallow groundwater and surface water applications.

It combines pressure and temperature sensors, hydrophobic filters and datalogger within a 7/8" x 7" (22 mm x 178 mm) stainless steel housing. The AquaVent uses a gauged pressure transducer; it is open to the atmosphere via a vented cable to surface. Atmospheric pressure is applied to the transducer diaphragm, providing a cancellation effect for barometric pressure. This results in actual water level recordings. The vented cable and Solinst AquaVent logger are protected from moisture by built-in desiccants and hydrophobic filters. 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. The robust FRAM memory can hold up to 120,000 data sets when programmed in Solinst Levelogger® Software with a compressed linear sampling mode.

The AquaVent has options for communicating strictly with Solinst software and accessories, or integrating into a telemetry system, SCADA/PLC system, or a third-party datalogger. The AquaVent can communicate with Levelogger Software. It can be used with the Solinst Levelogger App and Interface, and the DataGrabber™. For deeper, hard to access applications, or areas that are humid or prone to flooding, the Levelogger Edge absolute pressure water level datalogger is also an option (see Model 3001 Levelogger Edge Data Sheet).

AquaVent Communication Wellhead
The AquaVent Communication Wellhead fits conveniently onto a 2" (50 mm) well casing (a 4" Well Adaptor is available). There are two options: the SP Wellhead has a connection for communicating with Solinst software and accessories; the SPX Wellhead has an additional connection for communicating with third party dataloggers or telemetry systems using MODBUS (RS-232/RS-485) or SDI-12 protocols. Each Wellhead contains four (4) 1.5V AA lithium batteries that power the AquaVent logger. They are user-replaceable and can last 8 years based on 1 reading per minute (the internal AquaVent logger battery is only used to maintain the clock). For permanent moisture protection, the Wellheads contain multiple built-in desiccants and have a hydrophobic filter where the vented cable terminates at surface.

AquaVent Wellhead Communication Cables
There are multiple ways to communicate with the AquaVent; convenient Wellhead Cables are available for each option.

 

USB Connector Cable for communicating with Solinst Levelogger PC Software. Connector Cable for Communicating with the Levelogger App Interface and DataGrabber. Connector Cables for Communicating using SDI-12 and MODBUS RS-232/RS-485 Protocols
For SP and SPX Wellheads For SPX Wellhead Only

 

AquaVent Vented Cable Options
AquaVent Vented Cable assemblies are available in custom lengths up to 500 feet. Vented cables contain power and communication wires, as well as a vent tube running the length of the cable. Vented cables provide direct read communication from the AquaVent 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 AquaVent logger and Wellhead, using stainless steel twist connections. A hanger bracket is included with each Wellhead to support the vented cable when deployed.

 

AquaVent Setup Using Solinst Software
When programming using Levelogger Software, use a USB Connector Cable to connect the AquaVent Wellhead to the computer. (The AquaVent can also be programmed using the Solinst Levelogger App on your smart device.) Levelogger Software is very intuitive; it automatically detects the type of datalogger connected. All in one screen fill in your project information and sampling regime. Settings can be saved for easy re-use. There are options for immediate start or future start and stop times. AquaVent time may be synchronized to the computer clock. The percentage battery life remaining in the Wellhead and the amount of free memory in the datalogger are indicated.
 

Convenient Sampling Options
The AquaVent can be programmed with linear, event-based, or a user-selectable sampling schedule. Linear sampling can be set from 1/8 second to 99 hours, with memory storage for up to 120,000 data sets using the compressed sampling option. Event-based sampling can be set to record when the level changes by a selected threshold. Readings are checked at the selected time interval, but only recorded in memory if the condition has been met. A default reading is taken every 24 hours if no “event” occurs. The Schedule option allows up to 30 schedule items, each with its own sampling rate and duration. For convenience, there is an option to automatically repeat the schedule.
 

Data Download, Viewing and Export
Data is downloaded to a PC with the click of a screen icon. There are multiple options for downloading data, including ‘Append Data’ and ‘All Data’. The software also allows immediate viewing of the data in graph or table format using ‘Real Time View’. The level data is automatically compensated for temperature, and the temperature data is also downloaded. The Data Wizard can be used to input manual data adjustments, elevation, offsets, and density. The software allows easy export of the data into a spreadsheet or database for further processing. The Solinst Levelogger App also allows you to view and save real-time, or logged data right on your smart device.
 

Helpful Utilities
The ‘Self-Test Diagnostic Utility’ can be used in case of an unexpected problem. It checks the functioning of the program, calibration, backup and logging memories, the pressure transducer, temperature sensor and battery voltage, as well as enabling a complete Memory Dump, if required. A firmware upgrade will be available from time to time, to allow upgrading of the AquaVent, as new features are added.
 

Solinst Levelogger App & Levelogger App Interface
The Levelogger App Interface uses Bluetooth® technology to connect your AquaVent to your smart device. With the Solinst Levelogger App, you can download data, view real-time data, and program your AquaVent. Data can be e-mailed from your smart device directly to your office (see Model 3001 Levelogger App & Interface Data Sheets).

DataGrabber™
The DataGrabber is a field-ready data transfer device that allows you to copy data from an AquaVent onto a USB flash drive key. The DataGrabber is compact and very easy to transport. It connects to the AquaVent Wellhead using the Direct Read Interface Cable. One push-button is used to download all of the data in a AquaVent’s memory to a USB device plugged into the DataGrabber. A convenient LED light indicates operation. The data in AquaVent memory is not erased, and logging is not interrupted. The DataGrabber uses a replaceable 9V battery (see Model 3001 DataGrabber Data Sheet).
