Hydro Services Nose Mounting Ground Feeler Weights

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)

The Nose Mounting Ground Feeler Weights allow current meters to be used closer to the streambed than with Columbus Pattern, but do not protect the meter from oncoming debris. When the weight touches the streambed the foot (bottom contact) is forced up into the weight, closing a contact giving a continuous contact signal at the winch. In countries such as Australia, they are not widely used due to the large amount of debris in the flood flows.

Hydrological Services Nose Mounting Ground Feeler Weights

• Streamlined shape offers less resistance to flowing water and has less effect upon meter rating
• Bright yellow epoxy coated weight or can be supplied unpainted
• Protects current meter against heavy debris damage

Hydrological Services have adopted the U.S.G.S.Columbus Pattern gauging weights which range from 7 to 135kg.

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.

All weights are corrosion resistant and are bright yellow epoxy coated or can be supplied unpainted.
