<br />DISCHARGE MEASUREMENTS AT GAGING STATIONS <br /> <br />13 <br /> <br /> <br />Figure 16.-lower section of ice rod for use with vane ice <br />meler. <br /> <br />Weight-hanger pins of various lengths are <br />available for attaching the sounding weight to <br />the weight hanger. (See fig. 19.) The stainless <br />steel pins are threaded on one end to screw into <br />the weight hanger and slotted on the other. <br />Sounding reilds <br />A sounding reel has a drum for winding <br />the sounding cable, a crank and ratchet ll8- <br />sembly for raising and lowering the weight or <br />holding it in any desired position, and a depth <br />indicator. Table 1 contains detailed informa- <br />tion on each of the five reels most commonly <br />used. <br />The A-pack reel is light, compact, and ideal <br />for use at cablewllY sites a considefltble distance <br />from the highway. (See fig. 20.) It can also <br />be used on cranes, bridge boards, and boat <br />booms. <br /> <br />II <br /> <br />n <br />H <br />^h <br />t <br />i <br /> <br />.... <br /> <br />( <br /> <br /> <br />-::a......
