The Contrec Model 515 (Application FA02) is a high-performance industrial add/subtract mass flow computer specifically optimized for continuous process lines requiring precise multi-channel mass aggregation and balancing. Tailored to perform real-time mathematical addition or subtraction operations on two separate flow channels, this advanced instrument evaluates independent frequency or analog transmitter signals to deliver an ultra-precise resultant mass flow rate and total. It can interface directly with field flowmeters or collect re-transmitted signals from other discrete flow computers within the plant network. Housed in a weather-tight IP65 industrial housing with a crisp backlit LCD screen, the Model 515 FA02 guarantees structural protection against moisture and dust in arduous process environments. Complete with programmable high/low level alarms, an adjustable 8-24V DC sensor power output, analog retransmission, and dual-port RS-232/RS-485 Modbus RTU telemetry, it serves as a robust custody transfer and balancing solution for modern B2B mass handling loops.
Key Product Features
- Dual-Input Mass Balancing: Engineered specifically for mass units of measure, providing real-time mathematical addition or subtraction over two independent process loops.
- Universal Signal Interfacing: Seamlessly processes inputs from a wide variety of frequency instruments (millivolt, reed switch, Namur proximity, pulse trains) or scaled 4-20mA analog loops.
- Onboard Transducer Excitation: Features an adjustable, software-controlled 8-24V DC output voltage from the front panel to directly power connected field flowmeters.
- Advanced Audit Trail Logging: Integrates a precise Real Time Clock (RTC) logger that captures over 1,000 entries of process totals, batch histories, and system tag statuses.
- Scalable Pulse Retransmission: Offers a programmable open collector pulse output with adjustable volumetric scaling factors and custom pulse widths for external PLC handshake loops.
