probe sleeve kit must be used. Probe sleeve kits provide both electrical insulation and lateral stability for the probe
(see F ig u re 6).

IMPORTANT! When using probe sleeve kits, a minimum length of 75 mm of probe canister must be contained within
the 3-inch riser. Check also t hat the full safe working capacity of the tank can be measured by the probe chosen.
• Probes specified for tanks with entries smaller than 3 inches must always be long enough to rest on the tank bottom
and not ‘hang’ in the riser adaptor (see Figure 7).
