2.2.3 Devices with integrated nominal diameter reduction
The device versions F1R and F2R offer an integrated nominal diameter reduction up to two
nominal diameter sizes to assure best results in accuracy and optimum measuring ranges; even
in pipelines with large diameters, which have been designed for a low pressure loss.
