Rosemount 1595 Conditioning Orifice Plate

Rosemount1 configuration

Configure Your Rosemount 1595 Conditioning Orifice Plate

Patented 4-hole conditioning orifice plate for differential-pressure flow measurement with minimal straight-run piping. Self-centering design eliminates installation alignment uncertainty. Conditions disturbed flow profiles upstream of the plate, allowing accurate measurement with as little as 2 pipe diameters of straight run (vs 10–40 for standard concentric orifices). Pairs with 1496 orifice flange union for installation between line flanges.

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.
