Levelogger® 5
Model 3001
The Levelogger 5 records highly accurate groundwater and 
surface water level and temperature measurements. It combines 
a pressure sensor, temperature detector, 10-year lithium battery, 
and datalogger, sealed within a 22 mm x 160 mm (7/8" x 6.3") 
stainless steel housing with a corrosion-resistant coating baked-on 
using polymerization technology.
The Levelogger 5 measures absolute pressure using a Hastelloy® 
pressure sensor, offering high resolution and an accuracy 
of 0.05% FS. Readings are stable in extreme pressure and 
temperature conditions. The Hastelloy sensor can withstand 
2 times over-pressure without permanent damage. Combined 
with the durable coating inside and out, the Levelogger 5 has 
high corrosion and abrasion resistance in harsh environments. 
The Levelogger 5 uses a Faraday cage design, which protects 
against power surges or electrical spikes caused by lightning. 
Its durable maintenance-free design, high accuracy and stability, 
make the Levelogger 5 the most reliable instrument for long-term, 
continuous water level recording.
