A selection of well caps and plugs for protecting monitoring boreholes and suspending equipment in-situ.
Levelogger Direct Read Well Caps
Direct Read well caps for "2-inch" and "4 inch" borehole linings are available for suspending single or two loggers (one Levelogger, one Barologger) together. These push-fit over standard well lining.
Both single and dual style well caps incorporate an additional 16mm diameter access port to allow the use of a water level dip meter without disturbing the logger. These are capped with a plug which can removed using a hex key.
The Internal Diameter of the "2 inch" well caps is 59 mm (to fit over 60mm OD lining). The height of the "2 inch" cap above the lining collar when installed is 100mm.

Levelogger Well Head Suspension Cradles
These aluminium wellhead suspension cradles are designed for Leveloggers suspended with either Stainless Steel or Direct Read Cable. Two 23mm diameter holes in the cradle base are designed to accommodate Levelogger Gold Direct Read Cable and connectors. The winged suspension arms can be pulled opened or closed to straddle borehole collars of between 80mm and 250mm in diameter.
These cradles are mainly used for temporary logging installations where security is not a concern or for attaching to borehole lining below existing security covers.

Torquer Well Plugs
Torquer well caps are a simple well plug incorporating two eyelets for securing loggers suspended on stainless steel cable.
Choose a Torquer well plug to match your borehole ID (minimum borehole lining ID in mm is indicated in description). Torquer well plugs are capable of expanding in excess of 10 mm above their minimum diameter to provide a water tight seal. Padlocks are not supplied.
For use with loggers, plugs can be supplied with a 2mm diameter vent hole to prevent pressurisation of the borehole during logging. Please be aware this does introduce a small opening in the plugs and consequently vented plugs should not be used for permanent sealing of boreholes, particularly where flooding can occur.

EnviroCap Well Caps
EnviroCaps with 2mm vent holes, are an alternative to Torquer well plugs. They are ideal for securing loggers suspended on stainless steel cable within 2 inch (48mm min ID / 60mm max OD) and 4 inch (96mm ID and 110mm max OD) diameter monitoring boreholes.
EnviroCap locking well caps are attached to the top of well lining, and include a ring for suspending cable. They feature an exclusive built-in magnetic locking system that is completely sealed from the outside environment eliminating the need for padlocks.
A 2mm vent hole can be added to the cap to prevent pressurisation of the borehole during use making these suitable for deployment with Leveloggers or other datalogging equipment.
EnviroCap's unique magnetic locking keys are universal - one key fits all caps.
