Overview

Overview Benefits Specifications Resources

SUTRON fused the ultra-reliable SDI-12 optical encoder with our state-of-the-art SatLink2 Logger technology to create an encoder that never forgets.

Dual Sensor

Setup SDR to measure a second stage using an analog* or SDI-12 sensor

Rating Table

Compute discharge using a rating table with up to 50 points

Averaging

Stage can be computed by averaging multiple samples over a user-set period

4-20mA output

Output stage or discharge using the 4-20mA circuit (requires SDR w/analog:SDR0001-4)
