The Contrec Model 515 (Application SC06) is a heavy-duty industrial steam energy flow computer engineered specifically for stacked differential pressure volumetric flowmeters, such as vortex or turbine meters fitted with stacked transmitters. Optimized for custody transfer and plant energy balancing, this sophisticated processing instrument implements generic differential pressure flow calculations while fully incorporating the reference calibration conditions of the primary meter. Mass flow and thermodynamic energy variables are dynamically resolved in strict accordance with the international IAPWS-IF97 Industrial Formulation (1997). The multi-mode processing core utilizes live analog temperature and pressure transmitter loops to accurately determine specific volume and specific enthalpy changes across water, saturated steam, and superheated steam phases. To expand the overall operational range without losing precision during low-flow processing states, the system natively integrates stacked volumetric analog flow inputs. Enclosed in a weather-sealed IP65 field-mounting enclosure featuring an alphanumeric backlit LCD display, it delivers exceptional data reliability and audit safety under severe plant constraints. Outfitted with an adjustable 8-24V DC sensor excitation supply, isolated 4-20mA analog retransmission, and dual-port RS-232/RS-485 Modbus RTU serial links, it ensures secure local tracking and definitive audit transparency.

Key Product Features

Volumetric DP Flow Specialization: Designed specifically for differential pressure volumetric flow sensors, incorporating primary field calibration states within real-time equations.
IAPWS-IF97 Thermodynamic Math: Implements comprehensive international formulations to resolve exact real-time specific volume and specific enthalpy across water, saturated steam, and superheated steam phases.
Stacked Transmitter Input Option: Configured to manage dual stacked differential pressure transmitters to extend overall operational flow turndown limits.
Onboard Transducer Power Supply: Features an integrated, front-panel adjustable 8-24V DC excitation output providing up to 50mA to eliminate separate field power loops.
Comprehensive Audit Trail Logging: Non-volatile flash memory combines with an internal Real Time Clock (RTC) data logger to securely capture over 1,000 entries of totals, rates, and diagnostic states.
