Accuracy and straight pipe length
• Connection with different size piping, valve or filter
Install straight pipes as needed with the lengths given in the table below.
If a device that is not listed in the table is installed either upstream or downstream,
contact the azbil Group for the length of the straight pipe section.
If reverse flow is also expected, it is necessary to have the same length of straight
pipe downstream as upstream.
*1: Do not connect a carbon steel pipe for pressure service (JIS G3454) or stainless steel pipe (JIS G3459)
that is larger than schedule 40. Doing so might cause a deterioration of accuracy. (If the pipe schedule
number is larger, the inner pipe diameter is smaller, resulting in reduced accuracy.)
*2: The straight pipe section lengths given in the right-hand columns above are for connection of a filter the
same size (internal diameter) as the MCF.
