Cox Exact Dual Rotor Turbine Flow Meters

Cox Exact Dual Rotor Turbine Flow Meters


For over 50 years, COX Flow Measurement has met the test of endurance, which can only be achieved by manufacturing a quality flowmeter with unsurpassed repeatability and linearity. COX meters remain one of the highest quality flow measurement instruments available with unmatched calibration uncertainty. COX Flow Measurement is a Tier 1 supplier to Rolls Royce and all products are manufactured under AS9001, ISO 9001 and other strict industry quality standards.

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.
