Perforated plate flow conditioner
A specially designed perforated plate flow conditioner, available from Endress+Hauser, can be
installed if it is not possible to observe the inlet runs required. The flow conditioner is fitted
between two piping flanges and centered with the mounting bolts. Generally, this reduces the
inlet run required to 10 × DN with complete accuracy.
