Suspension Wire/Rope Installation
When installing using a suspension wire or rope, the Levelogger is pre-
programmed and started using the software. It is then deployed using a
suspension wire or rope connected to the installation cap of the Levelogger
to the underside of a well cap. The data is retrieved manually, by withdrawing
the Levelogger, removing the installation cap and attaching an Optical Reader
directly to the datalogger. Data is downloaded to a desktop or laptop PC or by
using a Leveloader Gold.
Solinst supplies stainless steel suspension wire assemblies including SS stranded
wire and hooks available in a variety of lengths from 50 ft (15 m) to +500 ft
(+150 m), and Kevlar rope assemblies. Solinst also supplies a specially designed,
tamper-proof, vented, locking well cap known as the Enviro-Cap™ from which
the Levelogger can be suspended.
This type of installation is applicable to both submerged and barometric record
applications. Follow these steps to install the Levelogger using stranded cabling
and hooks:
1. Loop the cable through the coil 2 of the hook assembly, then wind the looped
strands several times around the hook shaft and pass through coil 1.
2. Pass coil 3 through the Enviro-Cap™ eyelet or Levelogger/Barologger eyelet
and snap coil 3 to the hook shaft.
3. If the Enviro-Cap™ is not used then some secure tie-off point should be used
or installed.
4. If installing a Barologger, ensure the suspension level is above the highest
expected water level.
5. When retrieving data and/or reprogramming the Levelogger, extract it from
the monitoring location, unthread the installation cap, interrogate and re-
suspend the unit rechecking the security of the wireline clamps each time.
