EX Turbine/High accuracy, wide viscosity range

EX Turbine EX Turbine

A turbine flowmeter for industry application that allows stable high accuracy measurement for the liquid with a wide range of viscosity including low Reynolds number area. It is suited mainly for petroleum, liquefied gas, and water flowrates.



High accuracy: ±0.2% RD is available.


High accuracy metering is possible even in low Reynolds number area.
