Note 2: The approximate size of the connection port (D) is 8 mm for the MCF0080 (1/4 inch), 15 mm for the
MCF0150/0151 (1/2 inch), 25 mm for the MCF0250 (1 inch), 40 mm for the MCF0400 (1 1/2 inch),
and 50 mm for the MCF0500 (2 inch).
Note 3: 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.
Note 4: MCF models and connecting pipe sizes are shown below.
▲ Pipe one size smaller than the MCF
● Pipe the same size as the MCF
+ Pipe one size larger than the MCF
Note 5: The figure below shows an example of the MCF0080 connected with a reducer. The accuracy is
within the specification range (±3 %FS).
When connecting the MCF to a pipe 1 size larger than the MCF port (for example, the MCF0080 to
a 1/2 inch pipe), to determine the straight pipe length, use the section of the table marked “Pipe one
size larger in dia. (connected with reducer).”
Note 6: The figure below shows an example of the MCF0150 connected with an enlarging pipe. The accu-
racy is within the specification range (±3 %FS).
Do not connect a smaller size pipe to the MCF without a straight pipe section. Doing so might cause
a reverse flow in the measurement module, even though there is a regular forward flow in the main
flow path. Therefore the display might indicate a negative value or an extremely low flow rate com-
pared with the actual rate.
