The 1330L is an integral orifice flow element designed for precise flow measurement in small flow applications, available in 1/2, 1, and 1-1/2 inch NPT sizes with flanged or threaded construction. It offers ±0.5% accuracy when calibrated and operates at a maximum temperature of 300°F (148.9°C) and pressures up to 3000 psig for 1/2 and 1 inch sizes, or 1500 psig for 1-1/2 inch. The unit features 316 stainless steel construction with options for Hastelloy C orifice plates, conforms to NACE MR-0175-88 for wetted materials, and has face-to-face dimensions of 3-11/16 inches for 1/2 and 1 inch threaded units or 4-1/16 inches for 1-1/2 inch threaded units. Flanged versions are rated Class 150 or Class 300 ANSI with corresponding weights up to 24.8 lb for 1-1/2 inch Class 300. It mounts directly to differential pressure transmitters via flat gasketed surfaces.
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.
