Diaphragm of measuring lenticular DIL. DN 0-200; PN 10-63 MPa

Diaphragm is a type of standard narrowing device (SD) made in the form of a thin disc with an orifice having a sharp rectangular (sometimes conical) edge on the inlet side of the flow. The purpose of the diaphragm is to measure the flow rate of the medium using the variable differential pressure method. DIL is a chamberless diaphragm, installed between the pipe flange connection spigots, for nominal pressure over 10 MPa to 63 MPa with nominal bore from Du 5 to Du 200 mm at medium temperature from minus 50 to plus 510º?.
