The Contrec Model 515 (Application BC03) is a high-performance industrial batch controller explicitly engineered for precise preset fluid dispensing and delivery verification using mass frequency or analog flowmeters. Designed to serve as a fast and flexible automation core, this versatile instrument executes accurate single-stage or two-stage batch control sequences to prevent hydraulic shock and safeguard localized plant equipment. To eliminate costly volumetric discrepancies and process wastage, the computing core integrates advanced dynamic overrun compensation to adjust for mechanical valve closure delays. Additionally, a built-in safety monitoring matrix provides continuous protection via integrated no-flow, leakage, and overflow error detection. Enclosed in a weather-tight IP65-rated housing with a clear backlit LCD screen, the controller features a smart front panel that allows authorized operators quick access to commonly used preset quantities. With standard RS-232 and RS-485 Modbus RTU serial communication channels, it delivers seamless data telemetry for automated terminal, loading, and chemical blending architectures.
Key Product Features
- Fast Dual-Stage Batch Control: Executes rapid, multi-stage dumping and filling sequences, providing quick access to preset authorization profiles directly from the front panel.
- Comprehensive Fault Detection: Minimizes system risks and guards pipeline assets through specialized automatic tracking of leakage, overflow, and no-flow pipeline faults.
- Flexible Universal Input Conditioning: Natively processes inputs from frequency tools (pulses, millivolt, Namur) or active analog loops, applying square law and multi-point non-linear correction filters.
- High-Capacity Transaction Memory: Built-in non-volatile storage captures a robust internal ledger of the last 1,000 transactions complete with precision time and date stamps.
- Detail or Basic Menu Selection: Configurable interface views allow plant engineers to select between a comprehensive “Detail” view or a streamlined “Basic” operational menu to match operator technical profiles.
