585 Annubar Primary Element (Severe Service)
SKU: 585
Severe-service annubar averaging pitot tube — same flow-sensing principle as the 485, engineered for extreme conditions: process temperatures to 1500°F (815°C), ANSI B16.5 2500# pressures, and aggressive media. Solid sensor construction (no welded joints in the wetted path) for failure-resistant operation in main-steam, hot-flue-gas, and high-pressure-pipeline service. Wide material range (316L, Hastelloy C-276, Alloy 800H) for chemistry compatibility. Used in power-station main-steam flow measurement and other applications beyond the 485's envelope.

Severe-service averaging-pitot primary element — engineered for severe-service and main-steam applications beyond the 485's envelope. Solid sensor design (no welded joints in the wetted path) provides failure-resistant operation in main-steam, high-pressure-pipeline, and aggressive-chemistry service up to ASME Class 2500. Available in 4 to 96-in. (100 to 2400 mm) line sizes. Wide material range — 316 SST, Alloy C-276, Alloy 800H (high-temperature main steam), and PVDF — for chemistry compatibility. Pairs with the 3051SMV / 4088 multivariable transmitters for compensated mass flow.

1195 Integral Orifice Primary Element
Integral orifice primary element for small line sizes (0.5 - 1.5 in. / 15 - 40 mm) — the orifice plate is permanently mounted in a precision-machined meter body, eliminating the centering uncertainty that plagues field-installed plates. Self-centering construction. Best for lab-scale, low-flow, sample-conditioning, and pilot-plant flow measurement where standard orifice fittings are too coarse. Pairs with 3051CFP / 3051SFP / 2051CFP assembled DP flow meters. Wide material variety for chemistry compatibility.

1495 Orifice Plate
Standard concentric / eccentric / segmental / quadrant orifice plate — the workhorse of differential-pressure flow measurement. Precision-machined per ASME / ISO 5167 standards. Sized to your line size, beta ratio, and material requirements. Used between standard 1496 orifice flange unions for installation. Best for general-purpose flow measurement on clean liquids, gases, and steam where conditioning orifice (405C / 1595) special features aren't needed.

1496 Orifice Flange Union
Orifice flange union — paired flanges with integrated tapping points for D-D/2 or flange-tap differential pressure connections. Designed to bolt around a 1495 orifice plate (or any standard orifice plate) and provide stable, leak-free pressure-tap take-offs to the DP transmitter. Slip-on or weld-neck flanges. ANSI 150 through 1500 lb pressure ratings. Carbon steel, stainless steel, or alloy options. The standard installation hardware for orifice-plate flow measurement.

1595 Conditioning Orifice Plate
Patented 4-hole conditioning orifice plate — four equally spaced orifices instead of the standard concentric single bore. The four-hole design conditions disturbed flow profiles (eddies, swirl, asymmetry from upstream pipe fittings) BEFORE measurement, eliminating the 10-50 diameters of straight run that ASME orifice plates require. Only 2 diameters upstream and 2 downstream needed — installs in tight piping where standard 1495 plates can't get enough straight pipe. Same materials and beta ratios as standard 1495 plates. Best for retrofit applications and crowded plants.
