Overview

The AquaVentq ventilated water level gauge can measure water level and temperature. The sensor is integrated into a 22 mm x 178 mm stainless steel housing. The AquaVent uses a pressure sensor, which is connected to the outside atmosphere through a trachea. The outside atmospheric pressure and the pressure from the water pressure cancel each other out, thus obtaining the net water level pressure. AquaVent adopts Hastelloy pressure sensor technology, which improves the stability and accuracy of data collection in harsh environments, and can withstand twice the overpressure environment.

Wellhead communication device

The AquaVent wellhead communication device can be installed inside the casing of a 50mm diameter well.

There are two types of devices to choose from. The first type is the SP model, which is only used for solist acquisition programs. The second type is the SPX, which not only has SP functionality but also provides multiple communication protocols, supporting RS-232, RS-485, and SDI-12.

Each communication device contains four 1.5V AA lithium batteries as the power source for AquaVent, which can work continuously for 8 years (based on recording data once per minute).

For moisture prevention, there are desiccants and hydrophobic filters inside the communication device.

Communication cable

There are many ways to communicate with AquaVent, among which the most convenient is through communication cables

● Suitable for SP and SPX (USB interface, application programming interface)

Suitable for SPX (RS-485, RS-232, SDI-12 interfaces)

Ventilation cable

The AquaVent ventilation cable assembly can be customized to a length of up to 500 feet. The ventilation cable includes a power line, a communication line, and an exhaust pipe. The insulation layer of the cable is made of polyurethane, which is solid and durable.

AquaVent software settings

Connecting AquaVent to Solinst parameter setting software is very simple. When connected to a computer and the parameter setting software is opened, the software will automatically find the port to detect the connection type.

In the software, basic information of AquaVent can be viewed, including serial number, firmware version number, pressure unit, temperature unit, compensation, etc. AquaVent data acquisition can range from 1/8 second/time to 99 hours/time. Future start and end times can be set.

The data collected by AquaVent supports multiple downloads, including all data and additional data, and can be exported to spreadsheets and database files for easy use and research by users.

AquaVent supports Bluetooth transmission. By installing the solist APP software on your phone or pad, you can view real-time data and download data through Bluetooth. Data can also be collected through the DataGrabber data acquisition card. DataGrabber uses a USB interface to transmit data and can read AquaVent data by connecting to a communication device. It is compact, lightweight, and easy to carry.
