	300mm to 600mm	±1.0% of reading (±0.010m/s at a flowrate less than 1m/s)

※1：The fluid must not contain bubble.

※2：Maximum applicable bore size may not satis by the requirement depending on the material or status of piping.

※3：In case of lining pipes, the lining must contact with the main pipe.(Lining material is tar epoxy or mortar, or the like.)

※4：Specification when measures volume flow.

※5：The pipe must be full of liquid and the flowrate distribution must be ideal.
