Solinst AquaVent 5 Ventilert Vannstands-logger

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.

Applications

• Ideal for shallow applications: up to 20 m (65 ft) submergence
• Aquifer characterization: pumping tests, slug tests, etc.
• Stream gauging, lake and reservoir management
• Watershed, drainage basin and recharge monitoring
• Wetlands and stormwater run-off monitoring
• Long-term water level monitoring in wells, surface water bodies and seawater environments

Features

• Gauged pressure sensor for highly-accurate water level measurements: 0.05% FS
• Multiple built-in hydrophobic filters and desiccants - no need to replace, reduces maintenance
• Easy-to-access, user-replaceable batteries in Wellhead
• Options for MODBUS (RS-232/RS-485) and SDI-12
• Separate cables for each communication protocol
• Use with Solinst software for multiple logging options including linear, event, and scheduled sampling

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.
