SUTRON SDR Stage Discharge Recorder

Description Détaillée

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. Averaging Stage can be computed by averaging multiple samples over a user-set period. Rating table Compute discharge using a rating table with up to 50 points.
