Model CD92TAR meter is for cold water, inferential, single jet type, super dry pattern, i. E. Dry dial, magnetic drive type, with the lower magnet fitted directly to the fan wheel which is the only moving part submerged in water, therefore this meter is ideally suited for operating with hard and scaling water with sand in suspension without the rapid deterioration of gears which in traditional designs are submerged in water. Its sealed register mechanism under vacuum prevents condensation problem.
