The Contrec Model 515 (Application MP01) is an advanced, high-performance volume flow computer uniquely engineered with integrated master prover logic to deliver “on-the-fly” in-line calibration validation for frequency volumetric flowmeters. Optimized for custody transfer and fuel distribution headers, this robust instrument calculates line mass and volumetric flowrates independently from proving totals. The secondary dual frequency channel accepts raw pulse data from a reference master meter, automatically calculating a recommended Meter Factor based on current flow conditions without interrupting active process loops. To compensate for harsh thermal and fluid variables, the computer integrates live analog temperature and pressure values, executing flow-weighted averaging rather than simple time averaging to maintain premium precision. Enclosed in a ruggedized, weather-tight enclosure featuring an adjustable backlit display, the Contrec 515 MP01 provides side-by-side 4-20mA retransmission, an adjustable 8-24V DC excitation supply, and dual RS-232/RS-485 Modbus RTU serial architecture for advanced refinery and pipeline telemetry hubs.
Key Product Features
- In-Line Master Prover Engine: Executes real-time, “on-the-fly” validation runs against a reference master meter to derive and recommend optimized Meter Factors.
- Flow-Weighted Analog Averaging: Mathematically integrates temperature and pressure analog readings over fluid volume rather than time to eliminate process data skewing.
- Dual Signal Tracking Paths: Maintains line flowrate parameters and master verification parameters completely independent of one another inside the calculation core.
- Onboard Transducer Power Output: Eliminates auxiliary field wiring overhead by delivering a software-controlled 8-24V DC excitation supply to power connected flowmeters.
- Remote Verification Control: Proving runs can be executed remotely via discrete rear-panel hardware inputs or through serial network commands.
