Installation: Sizing: Turbine flowmeters measure the average velocity of the flowing stream and this requires that the velocity profile of the fluid stream be symmetrical across the internal diameter of the flowmeter body when it engages the rotor. In order to assure that the flowing streams velocity profile is symmetrical, it is necessary to provide straight runs of pipe into and out of the flowmeter. For most applications, a length equal to 10 diameters of the nominal turbine meter inlet size upstream and 5 diameters of the nominal turbine meter inlet size downstream of the meter are...
