It is analogous to classical orifice plate, orifice plate bore is eccentric and when flow profile is oriented in the lower part of horizontal (inclined) piping, flow of impurities in the measured fluid is enabled. Due to use of eccentric orifice plate in petrochemistry, chemical and atomic industry, it is made of SST grade stainless steel and of steels with high content of nickel (inconell, hastelloy).
