3001 Levelogger 5, M5
The Hastelloy sensor has great performance and response times in extreme temperature and pressure environments. It can withstand 2 times over-pressure without permanent damage. The Levelogger 5 comes in different pressure ranges to suit expected water level fluctuations, from 5 m to 200 m (15 ft. to 600 ft.).
The sealed unit contains a temperature sensor that gives accurate readings (±0.05ºC) and provides temperature compensated water level values. The Levelogger 5 has a lithium battery that lasts 10 years based on 1 reading every minute. The internal datalogger has memory for 150,000 level and temperature readings.
For use in seawater, and for extra corrosion, abrasion and chemical resistance, the 22 mm x 160 mm (7/8" x 6.3") stainless steel housing has a durable coating (inside and out) baked-on using polymerization technology. The Faraday cage design provides protection against power surges or lightning strikes. The Levelogger 5 operates in temperatures from -20ºC to 80ºC (0ºC to 50ºC is the temperature compensation range).
Features:
Highly stable communication: single-eye optical interface—easier to clean, more scratch resistant
Large memory: 150,000 sets of data
Strong, robust design: double o-ring seals for increased leakage protection
High thermistor sensitivity: upgraded platinum RTD
Superior protection in harsh environments: corrosion and abrasion resistant coating—inside and out
Intuitive Levelogger Software: Diagnostic Utility for more proactive user “self-tests”
Applications:
Aquifer characterization: pumping tests, slug tests, etc.
Watershed, drainage basin and recharge monitoring
Stream gauging, lake and reservoir management
Harbour and tidal fluctuation measurement
Wetlands and stormwater run-off monitoring
Water supply and tank level measurement
Mine water and landfill leachate management
Long-term water level monitoring in wells, surface water bodies and seawater environments
