3 The analogue output current from the connected equipment
should be 2 0

A or less when selecting 0 to 1 0 V. When more
than 2 0
μ
A current fl ows, it is possible that the accuracy is not
satisfi ed below 0.5 V.

Flow Range
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.
∗
“Straight section” means a part of the piping without any bends or rapid changes in the cross
sectional area.
• When the PFMC7501 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.
