It is recommended to take a manual water level measurement before installing an AquaVent logger, shortly after installation, periodically during your monitoring interval, and at the end of your measurement period. Use these measurements to verify AquaVent readings, and for data adjustments later on. Ensure you take manual readings as close in time as possible to a scheduled AquaVent reading.
Before deployment, make sure you do the following:
- Program your AquaVent logger, using Levelogger Software, with the correct project identification, memory mode, sampling regime, time, etc.
It is useful to synchronize the times of all AquaVent loggers being used for the same project.
- Set a future start time in the office, or start the AquaVent logger in the field using Levelogger PC Software and a laptop, or the Solinst Levelogger App & Interface.
- Determine borehole depth to ensure AquaVent logger does not touch the bottom of the well (avoid submergence in sediment)
- Record the deployment depth of your AquaVent logger.
The length of the Vented Cable should not be assumed as the deployment depth, as there may be some slack in the cable, especially when using the hanger bracket.
- Use a Solinst Model 101 or 102 Water Level Meter to take a manual depth to water measurement that will be used to verify AquaVent readings
- Determine the minimum and maximum expected water levels, as AquaVent loggers must remain submerged for the entire monitoring period.
- The AquaVent system is designed to be conveniently installed on a 2" well casing (4" using an adaptor). However, other installations are acceptable, if proper precautions and recommendations are followed.
- The Wellheads have a rating of IP 64 (dust and splash resistant), so should not be submerged at anytime. They can be secured inside an enclosure, however, it must be vented to equalize atmospheric pressure.
- Do not drop the AquaVent logger into the water, carefully lower it into place. Avoid installing in areas where "water hammer" or hydraulic jump" (very sudden, large increases in pressure) may occur.
- Be careful not to nick or bend the Vented Cable during installation.
For tips, precautions, and more information on installations in different environments and applications, see the latest AquaVent User Guide.
After deployment, make sure you do the following:
- Take a manual depth to water measurement after the well has stabilized (approximately 10 minutes))
- Take another manual depth to water measurement just before removing the AquaVent logger from the well
