    Max.: 43.8 us gal/min (165.8 l/min)


The integral orifice is a flow element can be close -coupled with differential pressure transmitters to make a complete flow meter. It provides easy-to-install, low-cost measurement of the small flows found frequently in plant metering operations and research projects.

The 1330L can be ordered with internal NPT threads or flanged pipe runs, welded both upstream and downstream of the flow restriction. The orifice assembly may be directly mounted to the transmitter or remote using an optional adapter kit.
