*1 Analog output accuracy is within ±3% F.S.
*2 A and C will change according to the setting of the zero cut function.
*3 The analog output current from the connected equipment
should be 20 μA or less when selecting 0 to 10 V. When more
than 20 μA current flows, it is possible that the accuracy is not
satisfied below 0.5 V.
* The min. value of the rated flow range will change according to
the setting of the zero cut function.

IN Side Straight Piping Length and Accuracy (Reference Data)
• The piping on the IN side must have a straight section of piping with a length of 8 cm or more.
If a straight section of piping is not installed, the accuracy can vary by approximately ±2% F.S.
* The "straight section" refers to a section of piping without any bends or rapid changes in the cross
sectional area.
• When the PF2MC7501 or 7102 is connected to tubing, use a tube I.D. 9 mm or more just before
the product. The accuracy can vary by approximately ±2% F.S. when such tubing is not used.
