Description

The Solinst 3500 AquaVent 5 records accurate water level and temperature measurements in shallow groundwater and surface water applications. It is open to the atmosphere via a vented cable to surface that is protected from moisture by built-in desiccants and hydrophobic filters. Atmospheric pressure is applied to the transducer diaphragm, providing a cancellation effect for barometric pressure. This results in actual water level recordings. The sensor can withstand 2 times over-pressure without permanent damage.

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
• Stormwater and runoff monitoring
• Long-term water level monitoring in wells and surface water

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
• Corrosion and abrasion-resistant coating baked-on using polymerization technology
