Stream Gauging Model GFN
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.
