The Ground Feeler Device is a mechanical spring loaded attachment that is used in conjunction with any gauging winches fitted with Amegraph cable and connected to Columbus pattern gauging weight.

The unit is designed to alert the operator that the gauging weight has come in contact with the streambed during gauging operation.

When the gauging weight contacts the streambed, the GFD causes the current meter signal to short-circuit. The operator will hear a continuous beep emitting from their current meter counter, or with various models of counters, there will be no signal received from the current meter. Either of these events indicates that the gauging weight is in contact with the streambed.

Once the weight is raised slightly off the streambed, normal current meter signal operation will commence.

The GFD eliminates the need to observe the main cable movement on a cableway to determine if the gauging weight comes into contact with the streambed. In situations where the distance is too far to observe the main cable movement, or in a harsh weather conditions, the GFD makes streambed sensing an easy and accurate procedure.
