FlowTrak Flow Conditioner

Sierra Instruments’ Flow Conditioning Plates represent an economical solution to problems associated with monitoring flow installations where

long, straight runs of piping are not available.


The flow conditioning element effectively eliminates velocity profile distortions, swirl and temperature stratification in the gas stream. The flow conditioner creates a uniform velocity profile by means of two stainless steel perforated plates. Designed to work in schedule 40 pipe ( other scheduals contact factory) with 150# flanges, the front flow conditioning screen is sandwiched between two 150# flanges, along with two 1/8” gaskets (gaskets and flanges are supplied by customer). The flange mounting bolts serve to center the screen in place.

The flow plates reduce upstream piping diameters to
less than three diameters after most common flow disturbances. Extensive testing has demonstrated that this device virtually eliminates the effect of piping conditions with fewer upstream diameters than any other flow conditioning technique.

Flow plates may be purchased separately for general flow conditioning or they may used with existing Sierra insertion meters if calibrated as a set.
