Combining high accuracy T3000 Turbine Meter measurement with a C700 Positive Displacement Meter in one assembly, the C3000 exceeds the performance required in AWWA Standard C-702. For selection of the appropriate chamber for measurement, the assembly includes a differential pressure valve downstream of the turbine measuring chamber that remains closed during low flows, causing all flow to be measured by the Positive Displacement chamber. When flows exceed about 1/2 the rated capacity of the PD meter, the valve opens, allowing the Turbine measuring element to capture high flows. Compound Meters are available in sizes 2" to 8".

The C3000 design is modular, facilitating maintenance. The drop-in measuring element of a standard T3000 Turbine meter allows fast change-out of the high-flow element when required. A standard C700 Positive Displacement meter can replace the by-pass line meter as required. Long life designs for both the turbine and positive displacement meters, coupled with a high-performance valve, minimize repair.

For utilities desiring the efficiency and safety of advanced reading technologies, Encoder, Digital or Pulse Generator registers are available for all C3000 meters.
