Select "BI DIRECTION" (Direct / reverse flow measuring mode) in
parameter number "B10 ".
Reverse direction span can be set in parameter No."B30".
Flow rate unit is the same as forward direction span.
Further reverse range span should be set in the same number of places of
decimals as forward range span.
Example: forward flow rate : 1.000 then reverse flow rate should be 4.000.
Hysteresis width at switching direction can be set in parameter No."B31".
It is the rate(%) of the smaller span, either forward or reverse span.
