Loading...

Stage Discharge Recorder (SDR)

    • 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

    • 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.
