*1 The rated flow range indicates the range that is supposed to be used in general.
*2 The rated flow range indicates recommended operating range.
*3 Can be used within the display range as well as within the rated flow range.
*4 Flow under the zero cut flow will be displayed as 0 L/min.
*5 The repeatability is effective within the display range. Convert the F.S. (full scale) listed in the table ac
*6 Maximum 20 mA for alarm output.
