Notes:
*1. The unit L/min (normal) refers to the volumetric flow rate adjusted for 0 ˚C, 101.325 kPa.
*2. Flow is displayed as a negative value without changing the setting.
*3. Indication value and integrated pulse output can be displayed and output without changing the setting, but 4–20 mA output requires a change of the span setting.
*4. The guaranteed accuracy range figures are ±3 % FS.
*5. Integrated pulse output specifications (selectable by settings)
