Product Options

Overview

The new Solinst AquaVent delivers accurate water level and temperature measurements in shallow groundwater and surface water applications up to 65 ft (20 m). It consists of pressure and temperature sensors, hydrophobic filters and datalogger housed within stainless steel measuring 7/8” x 7” (22 mm x 178 mm). Its design utilises hydrophobic filters and permanent factory installed desiccants making the AquaVent virtually maintenance free.

The AquaVent comprises of a gauged pressure transducer that is open to the atmosphere via a vented cable to the surface. Atmospheric pressure is applied to the transducer diaphragm, applying a cancellation effect to the barometric pressure. This produces a water level recording.

The vented pressure sensor has been designed using Hastelloy®, making it extremely durable whilst maintaining its accuracy in various temperatures and monitoring applications. The sensor produces an accuracy of 0.05% FS and is capable of withstanding 2 times over-pressure without any permanent damage.

The Aquavent is compatible with all Solinst Levelogger Software and App, offering multiple logging options including linear, event and scheduled sampling. There is also the option of communicating through telemetry systems using MODBUS (RS-232/RS-485) or SDI-12 protocols. The AquaVent is available in ranges of 5, 10 and 20 metres.

FAQ's

Water level data from remote Leveloggers can be sent using the model 9500 LevelSender, which uses a GSM cellular modem to send the data to a home computer station or mobile device via email/SMS.
Leveloggers are connected to LevelSenders using a Reader cable which connects to the Levelogger’s Direct Read Cable. This can be done by removing the black dust cap from the LevelSender, lining up the holes and pushing the Reader Cable connector into the LevelSender connection and screwing the Reader Cable into the connection on the LevelSender until tight. Then connect the other end of the reader cable to the top end of the Levelogger’s direct read cable.
Within the diagnostic utility there is an option called ‘read memory dump’ this will access previous logs from a backup location. This dumps all of the Leveloggers memory into a .xle file.

The free app is available on both Apple® and Android™ smart devices.
Apple devices must be running iOS 11 or later on the following compatible devices:

  • iPhone
  • iPad
  • iPad mini
  • iPod touch.

Android devices must be running version 5.0 or higher. Solinst does not guarantee compatibility on all devices running 5.0, but testing confirms the following can be used:

  • Phone: Samsung Galaxy S4 - Model SGH-1337M
  • Phone: Samsung Galaxy S5 - Model SM-G900W8
  • Tablet: Samsung Tab 4 (10.1”) - Model SM-T530NU

As the Levelogger App Interface will not connect directly to the top of a Solinst datalogger, it is necessary to have connection accessories. With the Levelogger or Rainlogger, one of the following accessories is required:

  • Direct Read Cable, clients use this option to suspend dataloggers in the field when they wish to communicate downhole.
  • When working with Leveloggers that are suspended from wireline, or cord, the units must be removed from the well and connected to either a Direct Read Cable (as above) or an Optical Adaptor.
  • For the LevelVent, just connect to the unit via the Vented Cable and LevelVent Wellhead that all units are suspended from in the field – no other connection accessories are required.
  • The AquaVent communication connection is made from the App Interface to the AquaVent Wellhead using an App Connector Cable that is ordered separately.
The Levelogger App Interface is portable hardware that connects to the top of your Levelogger via a Direct Read Cable/Adaptor, to a LevelVent Wellhead, or to an AquaVent Wellhead cable. Bluetooth wireless technology allows communication between the Levelogger App Interface and the smart device with the app installed. It allows viewing/downloading of data, and programming of Solinst dataloggers, as well as many other features.
Solinst offers a wide range of dataloggers that can be used with the Leveloggger App Interface. They include the complete, current Levelogger Edge range of units (Edge, Junior Edge, LTC Edge, Rainlogger Edge), previous Gold Leveloggers/Barologgers, and the latest vented datalogger editions, the AquaVent and LevelVent.
  • Program and start dataloggers in the field.
  • Simplify data management in the field by transporting and using less equipment.
  • View real-time readings.
  • Download and e-mail logged data files.
  • Calibrate LTC Leveloggers (NEW).
  • Run the diagnostic utility (NEW) – used for troubleshooting
