An integrated orifice meets the ASME MFC-14M standard for flow measurement in pipework from 6mm in diameter and offers a complete set with differential pressure primary element and upstream and downstream straight lengths for optimum measurement accuracy. It is equipped with special flanges for direct mounting of the transmitter.

According to ASME MFC-14M, an integrated orifice is a complete flow measuring device: it includes the primary measuring element (orifice plate), the special flanges, the corner pressure taps (0/0) and upstream and downstream straight lengths. It is designed to fit directly on small pipes up to DN 40.
