Double duty flowmeter

As fluid passes through Exact Flow’s new DX-DL dual-rotor turbine flowmeter, the dual rotors become hydraulically coupled due to their counter-rotation. Not only does this allow the rotors to overcome the inertia and drag that typically affect single-rotor turbine flowmeters, it also extends the flow range to 500:1—five times the 100:1 flow range of a single-rotor flowmeter.

The dual-rotor system also cancels out rotor acceleration so that flow strengtheners are not required to control process fluid swirl. The extended flow range capability allows for the deployment of fewer flowmeters to cover a wide range of flow. This eliminates the need for manifold systems, which simplifies installation and maintenance and lowers costs. (
