Amergraph Cable

This cable is commonly used for stream gauging. It is a double purpose cable which is specially constructed to permit the suspension in the stream of the current meter and heavy ‘‘Columbus’’ weights and at the same time provide a medium through which the meter signals are carried to a counting device.

The Amergraph Cable consists of an insulated inner core of 6 copper and 6 stainless steel wires wound to the left, whilst the outer strands consist of 15 galvanised wires wound to the right. Alternatively a single galvanised wire tape cable can be used for supporting the weight and meter and acting as a return wire whilst an additional external bell type wire is then required as the other leg of the circuit.
