Hydro Services Columbus Pattern Gauging Weight

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

These streamlined weights maintain a steadier position in water flowing at high velocities and align the current meter into the flow. They also offer less resistance to flowing water and have less effect upon the meter rating. They are longer than the current meter, thereby offering some protection from bridge piers and flowing debris. The hanger bar is attached to the weight and the Current Meter is mounted on the hanger bar. This assembly is suspended from a gauging winch with an armoured signal cable. Hanger bars are used to suspend the gauging weights below the OSSBI Universal Current Meter and are available in two sizes.
