Pre-assembled DP flow meter combining the Rosemount 485 Annubar averaging-pitot primary element with the Rosemount 3051S pressure transmitter. Best for line sizes ≥ 2 in where orifice plates introduce excessive permanent pressure loss. Lower installation cost than orifice for large lines (no flange unions, no bolted-in plates). HART or FOUNDATION Fieldbus output. Suitable for liquid, gas, or steam.
Rosemount is configurator-heavy and quote-only — Valley Instrument verifies option compatibility, lead time, and pricing before confirming your order.
