Daniel Straightening Vanes

Daniel

Daniel™ Straightening Vanes minimize the adverse effects of flow disturbances by generating a consistent flow profile. Installed upstream of a Daniel Orifice Fitting or Daniel Ultrasonic Flow Meter, these devices smooth out and straighten the fluid flow to reduce measurement uncertainty by minimizing the effects of swirl, turbulence and other costly flow disturbances caused by insufficient straight pipe and/or valves. The straightening vanes also allow for shorter upstream pipe lengths and can significantly reduce space requirements, installation costs and startup time.
