Economical two-path liquid ultrasonic flow meter for check metering and allocation — two mid-radius parallel-plane measurement paths minimize uncertainty from disturbed flow profiles. Four transducers measure transit-time difference between upstream and downstream paths. Best for check metering downstream of custody-transfer 3814 / 3818 installations, allocation measurement on multi-product blends, or as a primary meter where 4-path 3814 accuracy is over-spec. No moving parts, full-bore meter, virtually no pressure drop. Pairs with the Rosemount 3810 Series Electronics module. Transducer + electronics + body material are application-engineered — Valley Instrument's sales engineer reviews your flow rate / fluid / line conditions and derives the PDS-correct model number for the formal quote.
