97% and 101.5% at the AWWA specified low flow. Accuracy tests are made before shipment, so no adjustments need to be made before installation. CONSTRUCTION The meter consists of a straight through-flow main case, dual inlet measuring chamber, vertically grooved oscillating piston, high capacity strainer, removable

This standard covers the various types and classes of cold water displacement meter in sizes 5/8-6 in., and the materials and workmanship employed in their fabrication.

The C700’s uniquely designed chambers, with dual-stage pistons, are custom engineered for performance exceeding applicable AWWA standards. Nylon materials are selected for strategically placed wear areas, providing long life and reduced noise.

put capability to the standard C-700 register (retains register read-ability). The output is an open collector current sink (NPN) (20 mA max.) magnetically actuated to provide a 50/50 open/closed ratio. Supply voltage 6-24 VDC; supply current 13.5 mA (max.). The unit is rated NEMA 4 for water and dust protection. Note: Register hous-
