Model 3001 Levelogger Edge and Barologger Edge

The Model 3001 Levelogger® Edge provides absolute precision when automatically recording changes in water level (pressure) and temperature. It is a self-contained (non-vented) datalogger, that uses a superior, corrosion-resistant, Hastelloy® pressure sensor with an accuracy of ±0.05% FS.

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 Edge comes in different pressure ranges to suit expected water level fluctuations, from 15 ft. to 600 ft. (5 m to 200 m).

The sealed unit contains a temperature sensor that gives accurate readings (±0.05ºC) and provides temperature compensated water level values. The Levelogger Edge has a lithium battery that lasts 10 years based on 1 reading every minute. The internal datalogger has FRAM memory for 40,000 level and temperature readings, or up to 120,000 using the compressed linear sampling option.

For use in seawater, and for extra corrosion and chemical resistance, the 7/8" x 6.25" (22 mm x 159 mm) stainless steel housing is coated in a Titanium based PVD finish. The Faraday cage design provides protection against power surges or lightning strikes. The Levelogger Edge operates in temperatures from -20ºC to 80ºC (0ºC to 50ºC is the temperature compensation range).

The Levelogger Edge is programmed using the intuitive Levelogger PC Software, or alternatively using the Solinst Levelogger App and Interface. Optical infrared communication allows multiple installation options, including stand-alone, or Direct Read communication. There are many convenient accessories and remote monitoring options to suit each application.

The Levelogger Edge can be set to record as often as every 1/8 of a second, up to every 99 hours. There are linear, event-based, and scheduled sampling mode options. Scheduled sampling is ideal for groundwater professionals conducting aquifer characterization tests.

Because Leveloggers are absolute dataloggers, they measure both water pressure and barometric pressure above the sensor. Using a separate Barologger Edge is the most efficient and accurate method to obtain simultaneous barometric readings in air. The readings can be used to subtract from the Levelogger data, to obtain true water levels.

The Levelogger Software Data Wizard allows multiple Levelogger files to be compensated at once, using one Barologger file. Only one Barologger is required within a 20 mile (30 km) radius, or with every 1000 ft. (300 m) change in elevation.
