The QCM Series internal kit permits maintenance requiring limited downtime by eliminating the need for the meter to be removed from the line for servicing. The kit contains all internal parts of the meter: rotor, bearings, support assemblies, and snap rings. The Quick Change Meter series provides +/- 1.0% standard linearity and is repeatable to +/- 0.15% over the designed flow range. Turbines, Inc. documents the K-factor for each meter by means of a NIST-traceable factory or independent laboratory calibration.
