  1. Hydrological Services Pty Ltd Sydney, Australia CMC3 ‘Hydromate’ March 2009

  2. PRODUCT DESCRIPTION • ‘State of the art’ stream gauging computer • Completely ‘paperless’ • Fan equations easily stored in unit • Automatic calculation and display of cross-sectional area, mean velocity and discharge • Data downloaded as a ‘text’ or ‘csv’ file to database in office • Powered by ‘D’ cell rechargeable batteries (2x1.5V) • ‘Non’ volatile memory • Software available in either English or Spanish versions

  3. Mechanical Features • Waterproof Case Dimensions : 210mm x 170mm x 90mm • Weight :1.5kg • Operating Temperature :-5 degrees C - + 55 degrees C • Humidity :0 - 100% Waterproof • Enclosure Rating : IP65

  4. Electronic Features • Graphics LCD and Touchscreen • Internal rechargeable batteries (mains and car charger provided) • Standard connection of Fan • RS232 serial port for PC operated configuration • Easily upgradeable to new software versions • ‘Backlighting’ of LCD

  5. Technical Features • Calibration formulas for up to 32 Fans stored in ‘non-volatile’ memory • Discharge for up to 30 Sites can be measured • Up to 30 verticals per site and up to 11 points per vertical • Measures both instantaneous and average water velocity • Either ‘Mean’ or Mid-Section’ computation options available • Fully charged gives 20hrs operation (no backlight) OR 5hrs (with backlight)

  6. Maintenance • Do NOT charge the Hydromate while it is operating • Do NOT charge Hydromate if alkaline batteries are installed • Do NOT use ballpoint pen on touch screen • Do NOT use excessive finger pressure on touch screen • ‘Clean the Touchscreen feature’ (when unit is operating)

  7. External Connectors ON / OFF button RS232 / Charger port Fan connection (banana type plugs)

  8. Hydromate Operation After first press of ON/OFF button, this screen will appear

  9. Screen Customisation Upside Down View Normal Operation Left hand operator Right hand operator

  10. Data Entry Press ‘Save’ move to next screen Press ‘Change’ - cycle between selections OR - numeric key pad OR - alphanumeric keypad will appear Press ‘Escape’ to exit WITHOUT changes saved

  11. Fan Selection • Displays factory calibration parameters as per calibration report • ‘New Fan’ - displays up to 32 fans that can be customised with calibration data • ‘Edit Fan’ - ’ allows customisation of calibration details using ‘change and save’ buttons • Use cursor buttons, ‘Save’, ‘Change’ and ‘Escape’ buttons as required

  12. Fan Calibration Formulae Three Step Formula n < 0.99 V = 0.1374 n + 0.0828 0.99 < n < 8.12 V = 0.1429 n + 0.0774 n > 8.12 V = 0.1510 n + 0.0116 Two Step Formula n < 4.21 V = 0.1374 n + 0.0828 n > 4.21 V = 0.1510 n + 0.0255 Enter Data as: n < 4.21 V = 0.1374 n + 0.0828 4.21 < n < 4.21 V = 0.1374 n + 0.0828 n > 4.21 V = 0.1510 n + 0.0255 One Step Formula All n V = 0.1374 n - 0.0828 Enter Data as: n < 5.00 V = 0.1374 n - 0.0828 5.00 < n < 5.00 V = 0.1374 n - 0.0828 n > 5.00 V = 0.1374 n - 0.0828

  13. Start New Gauging • Check battery voltage • Select screen contrast, backlight and screen orientation • Set display units • Set discharge computation method (mean or mid-section) • Set clock to local time • Select site

  14. Enter Gauging Details Site name : Enter a 20 character alpha-numeric string. Time & Date: Automatically inserted when a discharge commences. Control: None / Checked / See Notes Method : Wading / Traveller / Cable / Boat / Bridge Rods: Top Set / Cable / Bottom Set Measure: Surface = 0 / Bed = 0 Staff Gauge: Enter gauge height when commencing measurements – optional. Weight Offset: Offset from weight to centre of Fan (Measurement point = Measured depth – Weight offset)

  15. Enter Chainage / Sounding Details Type= WELB / Mid Stream / WERB #Points= Measurement points on this Vertical : 0,1,2,3,4,5,6,9,11 Staff: Enter Staff Gauge height – optional. Distance= Distance across the river from reference point to this vertical Dry Depth: Where applicable Wet Depth= Water Depth at this Vertical Wet Angle: Where applicable Wet Depth= Water Depth at this Vertical : Signifies ‘Optional’ = Signifies ‘Used in Mathematical Calculations’

  16. ‘Measure’ Function • During Measurement – instantaneous velocity • (averaged over the previous 5 seconds) • After measurement – average velocity • (averaged over entire timing period)

  17. Plot Function • Allows operator to plot PART or ALL of the gauging section • Displays ‘panel’ and ‘overall’ discharge for the gauging

  18. Hydromate Interrogator Software • Allows data to be uploaded from the Hydromate to a PC • Software loaded by inserting CD into PC • Fan calibration details can be ‘set’ or ‘retrieved’ • Gauging data can be downloaded in CSV format

  22. ‘Mean’ Section Method “The total discharge (Q) is the product of the distance between verticals by the sum of the products of the mean of the depths of two adjacent verticals by the mean of the average velocities over those two verticals “ Q = v1*BF*(d0+d1) + (v1 + v2)*(d1 + d2) b2 + (v2 + v3)*(d2 + d3) b3+ etc 2 2222 NB: Discharge within ‘panels’ near each bank is computed after selecting a ‘Bank Factor’ (BF) on the CMC3

  23. ‘Bank Panel’ Velocity Factor Applies to ‘Mean Section’ Method only The operator will need to make a judgement, based on his/her observation to determine a factor to apply to mean velocity measured in verticals closest to each bank and enter this factor into the CMC3, in EACH of the Water’s Edge verticals * Based on calculation from AS3778 Part 3.1 ‘Measurement of water flow in open channels’

  24. ‘Mid’ Section Method “The total discharge is the sum of the products of the average velocity in each vertical by the depth of that vertical and by the mean width of the two panels adjacent to the vertical “ Total Discharge = V1d1( b1+ b2) + V2d2( b2 + b3)+ V3d3( b3+ b4) etc 22 2 This method assumes ‘zero’ velocity within ‘panels’ near each bank

  25. Battery Replacement • Remove 6 screws on base of Hydromate • Remove electronics assembly • Remove batteries and replace with alkaline type • Use good quality ‘Energiser’ or ‘Duracell’ brand DO NOT TRY AND CHARGE STANDARD ALKALINE BATTERIES
