The axial design PRECISION TURBINE FLOWMETER is inherently linear within a known turndown range, typically 15:1, based on velocity of the measured fluid. The device has unmatched capability of precise and repeatable K-Factor generation based on the turning of the balanced rotor and the subsequently generated frequency pulse signal via the magnetic coil assembly, providing accuracy of +/-.15% with special calibration applied. Each pulse generated represents a discrete amount of volumetric throughput. Dividing the total number of pulses generated by the specific amount of liquid product that passed through the PTF determines the K-Factor.
Put in the simplest of terms, K-Factor is no more complicated than understanding that the meter will generate a specific number of pulses for every unit of product passing through it. If the user can detect the pulses, then it is a straightforward task to determine flow rate and totals. The K-Factor, expressed in pulses per unit volume, may be used to electronically provide an indication of volumetric throughput directly in engineering units.
