Water Level Datalogger

The Levelogger Edge is a self contained, automatic water level and temperature recording device. It combines a Hastelloy pressure sensor, temperature thermistor, 10-year lithium battery, and a datalogger with FRAM memory for 40,000 sets of data points, or up to 120,000 using the new compressed linear sampling option. All components are sealed within a
7/8" x 6.25" (22 mm x 159 mm) stainless steel housing with corrosion resistant Titanium based PVD coating.

The Levelogger Edge maintains the high resolution of previous Leveloggers, and an accuracy of 0.05% FS. The new, more precise Barologger Edge provides the easiest and most accurate method of barometric compensation.

Battery life is 10 years based on a 1-minute sampling rate. The Levelogger Edge also inherits the 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 Edge the most reliable instrument for long-term, continuous water level recording.
