What length of straight piping is required on the IN side of a PF2A series digital flow switch?

For accurate flow recognition, a section of straight piping 8 times the piping port size is required on the inlet side. When installing a throttle valve, etc., installing it on the outlet side is recommended. When installing a throttle valve on the inlet side, provide a sufficient length of straight piping immediately before the flow switch.
