Instructions on using the Qmax menu (flow range end value)
The device is factory calibrated to the flow range end value Qmax
DN
, unless other customer
information is available. The ideal flow range end values are approximately 2-3 m/s (0.2 ... 0.3 x
Q
max
DN).
The smallest and largest possible flow range end values are shown in the table in chapter 6.6
" Flowmeter sizes, flow range ".
