Detailed Introduction


Integral orifice primary element utilizes a self centering orifice plate design to eliminate installation error. Enables highly accurate flow measurement in small line sizes. Available with a variety of process connections. Available in ½" to 1½" (15 ~ 40 mm) line sizes.

Principle ● Improves accuracy and repeatability
● Self-centering plate design eliminates installation errors that are magnified in small line sizes
● Precision honed pipe sections allow accuracy of up to ±0.75% of flow rate
● Installation flexibility with numerous process connections
