Cox Exact Dual Rotor Turbine Flow Meters are the pinnacle of turbine meter technology that delivers results not attainable with single rotor designs. The Exact meter’s hydraulically coupled helical dual rotor design provides exceptional performance and many unparalleled benefits.
The patented dual rotor design extends the flow measurement range, due to the high incidence angle on the second rotor, resulting in turndowns of 120:1 on the smallest meter to 500:1 on larger meters. This exceptional flow range allows universal viscosity curves to blend over a 60:1 turndown range. This wide flow range often eliminates the need for more costly manifold systems.

Benefits
* Superior absolute accuracy with wider UVC turndown ratios
* Cancelation of fluid swirl effects.
* Exceptional speed-of-response, with reduced pressure drop
* Rotor ratio diagnostics
* Provide less friction and can be used in water and hydrocarbons
* Greater turndown flow range, often eliminating the need for manifold systems
* Internals are rigidly clamped against a step in the bore, with rod and nut torqued design
* Calibrations performed in a NVLAP* accredited primary standards laboratory with audited uncertainty disclosure
