Stage Discharge Recorder
SDR-0001-1

		THE SHAFT 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 option SDR-0001-3 or -4) SD Card Option*

Are You Required To...

Monitor discharge in canals & ditches for regulatory reasons?
Provide daily, weekly, or monthly reports on water usage?
Would you like to be able to...
Immediately see STAGE/ DISCHARGE at flume/weir sites?
Download up to 6 MONTHS OF DATA to Pocket PC or Laptop?
Have DATA IN SPREADSHEET-FORM for easy processing?
Have a RECORD SHOWING WHEN A SITE WAS VISITED & WHAT CHANGED?
Buy REPLACEMENT BATTERIES at a HARDWARE STORE?
Have NO FEAR OF LOSING DATA if the battery does go dead?

If you answered “Yes!” to any of these questions, then you need a STAGE DISCHARGE RECORDER.

KEY FEATURES

Sutron’s ultra-reliable SDI-12 optical encoder fused with logger technology from our state-of-the art SatLink-2 Logger/Transmitter to create an encoder that never forgets.

Using proven float-tape-counterweight technology, the STAGE-DISCHARGE RECORDER is a “plug compatible” replacement for a Stevens strip chart or punched-tape recorder.
The STAGE-DISCHARGE RECORDER saves your data in ultra-reliable Flash memory.
This means that there are NO BACKUP BATTERIES for the memory and you NEVER lose your data.
STAGE-DISCHARGE RECORDERs incorporate standard flume and weir equations and can compute and log discharge totals and display discharge as well as flume/weir stage.
A built-in event log keeps track of when anyone views or downloads data or makes changes to the setup.
The STAGE-DISCHARGE RECORDER will run up to one year on an industrial alkaline battery.
You get your data as easily read CSV (Comma-separated variable) files that can be opened with any spreadsheet program.
All setup can be done from the front panel of the encoder, and download utilities are available for Pocket PC compatible PDAs and Windows laptops.

ORDERING

SDR-0001-1 or SDR-0001-1SD (with SD Card option)

RECOMMENDATIONS

1. Stilling well with minimum 8” diameter
2. 5/16” shaft float wheel/pulley with circumference of 12”, 18”, & 375mm. If the float wheel does not have an insulating hub, a PVC float must be used. (See Ordering Options)
3. Beaded wire/tape compatible with the float wheel.
4. Float/ counterweights.
5. 12-volt alkaline battery with capacity of at least 20 amp-hrs. (See Ordering Options).
