Stage Discharge Recorder (SDR)

Stage Discharge Recorder (SDR)



Order

Description

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.


Feature

  • 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)
  • With proven float-tape-counterweight technology, it’s a “plug compatible” replacement for a Stevens strip chart or punched-tape recorder.
  • Saves your data in ultra-reliable Flash Memory.
  • NO BACKUP BATTERIES and you NEVER lose your data.
  • Incorporates standard flume and weir equations
  • Computes and logs discharge totals
  • Displays discharge as well as flume/weir stage.
  • Built-in event log tracks events such as data views, data downloads, and setup changes.
  • Runs up to 1 year on an industrial alkaline battery.
  • Data delivered in easy-to-read & -open CSV files.
  • All setup can be done from front panel.
  • Download utilities available for Pocket PC-compatible PDAs & Windows laptops.
  • SD Card Option

Spesification

  • Measurements
Stage/Level measurements, Internal Temp, Battery. Note: a second stage can be measured via SDI-12 or via optional analog interface.
  • Automeasure Interval
15-minute default, 1, 5, & 10 minutes user selectable. 30 & 60 minute intervals also available.
  • Stage/Level Resolution
Shaft encoder with 400 count/revolution. Shaft is 5/16″ diameter. Supported wheel sizes are 1ft, 00.375 meter, 0.5 meter and custom. SDR-0001-3 supports analog input in place of the encoder. The analog input can measure a 0-5V sensor, 4-20ma sensor or resistive bridge sensor.
  • Stage/Level Range
+/-80 ft of calibration point
  • Calculations
Discharge using Parshall Flume, Broad Crested Weir equations, Dual Sensor, Ratin Table or general purpose equation with user entered constants. Calculation of daily volume and daily average stage.
