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 velocityDuring Measurement – instantaneous velocity (averaged over the previous 5 seconds) After measurement – average velocityAfter measurement – average velocity (averaged over entire timing period)

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

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

22 ‘Mean’ Section Method Q = v 1 *BF*(d 0+ d 1) + (v 1 + v 2 )*(d 1 + d 2 ) b 2 + (v 2 + v 3 )*(d 2 + d3) b 3 + etc “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 “ 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 FactorComment 90%*Normally applied to bank panels of rectangular or square shape 66%Normally applied to triangular shape bank panels 50%Normally applied to triangular shape bank panels 33%Normally applied to triangular shape bank panels * Based on calculation from AS3778 Part 3.1 ‘Measurement of water flow in open channels’

24 ‘Mid’ Section Method Total Discharge = V 1 d 1 ( b 1 + b 2 ) + V 2 d 2 ( b 2 + b 3) + V 3 d 3 ( b 3 + b 4 ) etc “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 “ This method assumes ‘zero’ velocity within ‘panels’ near each bank

25 Battery Replacement DO NOT TRY AND CHARGE STANDARD ALKALINE BATTERIES 1.Remove 6 screws on base of Hydromate 2.Remove electronics assembly 1.Remove batteries and replace with alkaline type 2.Use good quality ‘Energiser’ or ‘Duracell’ brand
