Sangamo Meter. radically different in operation from the induction andcommutating types of meters previously Sangamo meter is of the mercury flotation type. that a pivoted metallic disc carrying electric currentwould tend to rotate when under the influence of amagnetic field. The fundamental discovery of Faraday is veryingeniously utilized in the Sangamo meter. A copperdisc is enclosed in a suitable chamber made of mouldedinsulating material which is divided horizontally intotwo sections, the chamber being partially filled withmercury. In the lower part of the mercury chamberthere are imbedded two copper terminals which serveto conduct the current to the copper disc through theintervening mercury. The mercury serves the doublepurpose of conducting the current to the disc and ofbuoying up the disc so as to make the weight on the
