485 Annubar Primary Element
SKU: 485
Annubar averaging pitot tube primary element — measures the velocity-pressure profile across the full pipe cross-section by sensing at multiple insertion ports. Small in-pipe profile minimizes permanent pressure loss (energy savings) versus orifice plates. Pak-Lok or flanged hot-tap-installable for retrofit on operating lines. Used for liquids, gases, and steam in clean-process applications where a low-permanent-loss flow element is preferred over an orifice. Pairs with the 3051SMV / 4088 multivariable transmitters for compensated mass flow.

Averaging-pitot primary element with T-shaped sensor design — measures velocity pressure across the full pipe cross-section. Up to 0.75% flow-rate accuracy, lowest permanent pressure loss of any DP flow meter, available in 2 to 96-in. (50 to 2400 mm) line sizes. Pak-Lok and flanged hot-tap installable for retrofit on operating lines. Used for liquids, gases, and steam in clean-process applications where a low-permanent-loss flow element is preferred over an orifice plate. Pairs with the 3051SMV / 4088 multivariable transmitters for compensated mass flow. (Units are built to customer-supplied pipe ID + wall dimensions; line size codes act as nominal selectors.)

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.
