Overview

SDR is a Logging Shaft Encoder used in surface water & groundwater applications. Front panel programmable, it holds over one year of data, & operates for over one year on alkaline batteries. SDR supports dual sensors to measure a second stage using an analog or SDI-12 sensor. It supports rating tables and incorporates standard flume and weir equations.

Benefits

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.
