The Contrec Model 515 (Application PP01) is a high-accuracy, industrial-grade pressurized petroleum flow computer designed specifically to operate with high-security quadrature flowmeters. Engineered for custody transfer, fiscal monitoring, and heavy-duty petrochemical distribution, this advanced instrument calculates gross volume, net volume, and mass flowrates with premium accuracy by integrating real-time pressure, temperature, and density analog inputs. Volume correction calculations are processed in absolute compliance with global ASTM D1250-04 standards, covering crude oils, lube oils, and refined petroleum products. Designed for harsh industrial process environments, the computer is housed in a robust enclosure featuring a backlit display and a smart front panel that supports quadrature signal tracking for ISO 6551 Level B pulse security. With built-in 4-20mA retransmission, an adjustable 8-24V DC sensor excitation supply, and dual RS-232/RS-485 Modbus RTU serial communication ports, the Contrec 515 PP01 integrates seamlessly into complex SCADA networks and distributed plant architectures.
Key Product Features
- ASTM D1250-04 Volume Correction: Dynamically compensates for temperature, pressure, and fluid density to compute high-accuracy petroleum metrics under reference conditions.
- ISO 6551 Level B Pulse Security: Accepts dual-channel quadrature flowmeter inputs to deliver absolute signal verification and prevent pulse miscounts or loop line tampering.
- Onboard Sensor Power Supply: Minimizes local installation infrastructure by providing a front-panel adjustable 8-24V DC transducer excitation output to directly drive field flowmeters.
- Dual-Interface Industrial Telemetry: Standardized with simultaneous 4-20mA analog loop retransmission and digital serial ports supporting Modbus RTU, Printer, and PC protocols.
- Extensive Real-Time Logging: Built-in non-volatile memory features an integrated Real Time Clock (RTC) data logger capable of capturing over 1,000 entries for thorough process audits.
