The AquaVent system is designed to be conveniently installed on a 2" well casing (4" with an adaptor). However, other installations are acceptable, if proper precautions and recommendations are followed.
The AquaVent 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. The Wellhead measures ø 4.0" x 5.5" (102 mm x 140 mm).
Consider the use of an extended top cap style protective well head. This would allow full access to the AquaVent Wellhead components at the top of the monitoring well.
Ensure you connect your AquaVent logger to the Vented Cable, and the Vented Cable to the Wellhead. See Section 1.5.1 for connection instructions. See Section 8.2.2 for installation using the well cap base and the Support Hanger Bracket.
