9.1.1 Free Suspended Installations

Suspension Wire Installation

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). 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:

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.

Pass coil 3 through the Enviro-Cap™ eyelet or Levelogger/Barologger eyelet and snap coil 3 to the hook shaft.

If the Enviro-Cap™ is not used then some secure tie-off point should be used or installed.

If installing a Barologger, ensure the suspension level is above the highest expected water level.

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.
