Aquavent 5 vented datalogger

Aquavent 5 vented datalogger

The AquaVent 5 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 22 mm x 173 mm (7/8″ x 6.8″) stainless steel housing with corrosion-resistant coating.

Description

Características

The AquaVent 5 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 5 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 memory can hold up to 150,000 data sets when programmed in Solinst Levelogger® Software.

  • 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 AquaVent 5

Funcionamiento

AquaVent 5 Communication Wellhead
The AquaVent 5 Communication Wellhead fits conveniently onto a 2″ (50 mm) well casing using the well cap base (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 4 1.5V AA lithium batteries that power the AquaVent 5 logger. They are user-replaceable and can last 8 years based on 1 reading per minute (the internal AquaVent 5 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.

Well head SPX

SPX Wellhead has an additional connection for communicating
with third party dataloggers or telemetry systems using MODBUS (RS-232/RS-485) or SDI-12protocols.

AquaVent 5 Vented Cable Options
AquaVent 5 Vented Cable assemblies are available in custom lengths of 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 5 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 5 logger and Wellhead, using stainless steel threaded connections. A hanger bracket is included with each Wellhead to support the vented cable when deployed.

Options

AquaVent 5 Setup Using Solinst Software
When programming using Levelogger Software, use a USB Connector Cable to connect the AquaVent 5 Wellhead to the
computer. (The AquaVent 5 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. Fill in your project information and sampling regime, all in one screen. Settings can be saved for easy re-use. There are options for immediate start or future start and stop times.
AquaVent 5 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 5 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 150,000 data sets.
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.

Aplicaciones

• 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.

Ventajas

• Automatic barometric compensation reduces time required for post data processing.
• Integrate into a third-party data collection system for remote real-time data.
• Continuous, reliable water level data for long-term monitoring projects.
• Actual water level readings for instant aquifer test results.
