Its robust design and advanced algorithms make it an indispensable tool for operations where precise and verifiable data is essential. The device’s ability to handle different media types, from liquids to steam, highlights its impressive adaptability and makes it a central component in many process control systems.

Certified for Heat and Cold Metering

A key feature of the ERW 700 is its certification for heat metering (MID MI-004) and cold water metering (PTB). These approvals are a testament to its accuracy and reliability, allowing it to be used in custody transfer applications, such as district heating. This means the ERW 700 can serve as a legally compliant billing counter for district and local heating systems. Furthermore, its approval for cold water metering makes it equally effective for cooling applications, offering a dual-purpose solution for energy management. These certifications provide users with the confidence that the data collected is not only precise but also adheres to strict international standards for commercial transactions. The device’s reliability in these critical applications ensures fair and transparent billing for end-users.

Logger Functions for Comprehensive Data Management

The ERW 700 is more than just a real-time calculator; it also incorporates powerful logger functions for comprehensive data management. These features allow the device to record a wide range of historical data, which is invaluable for analysis, auditing, and performance monitoring. The ERW 700 can log set day and monthly values, providing long-term trends and consumption patterns. It also includes period memory, error memory, parameter memory, and MIN/MAX memory, ensuring that no critical data point is lost. This detailed logging capability allows operators to track system performance over time, diagnose issues, and optimize energy usage. The ability to store this wealth of information directly on the device simplifies data retrieval and analysis, making the ERW 700 a highly efficient tool for any energy management program.

Flexible Inputs for Wide Compatibility

The ERW 700 boasts a highly flexible input system that allows it to be integrated with a broad range of existing sensors and flowmeters. It accepts various input signals, including 2 x 0/4…20 mA, 2 x pulse or frequency, and 2 x Pt100/500/1000. This versatility ensures that the flow computer can be combined with virtually all common volume flowmeters, such as ultrasonic, electromagnetic, Vortex, differential pressure, and Coriolis meters. This compatibility makes it an ideal upgrade for older systems, as it can leverage existing infrastructure without the need for a complete overhaul. The modular and expandable nature of its inputs and outputs further enhances its adaptability, allowing for up to 6 x 4-20mA and 7 x digital connections, as well as various communication protocols like mbus, Modbus, and Profibus.

Advanced Calculations and Precision Engineering

The precision of the ERW 700 is a result of its advanced calculation capabilities. It performs high-precision calculations for crucial variables like density, enthalpy, and compressibility. The device adheres to the rigorous IAPWS-IF97 standard for its water steam table, guaranteeing that all calculations related to water and steam are of the highest accuracy. The ERW 700 also includes a compensation input for a density signal, which further refines its calculations by accounting for variations in fluid density. This meticulous approach to measurement ensures that the data it provides is reliable and trustworthy, which is essential for both operational efficiency and financial accuracy in billing applications. This dedication to precision sets the ERW 700 apart in the field of flow and energy measurement.

Specific Applications for Diverse Industries

The ERW 700’s specific applications are diverse, making it an invaluable asset in numerous industries. A primary use is as a billing counter for district and local heating systems, where it accurately measures and records energy consumption for commercial purposes. In industrial processes, it can be used for condensate/steam measurement, helping to monitor and optimize energy usage in manufacturing plants. Its bidirectional measurement capability is crucial for systems that have flow in both directions, such as in certain HVAC or chemical processes. The heating/cooling switching function allows a single device to manage both heating and cooling systems, providing a comprehensive solution for climate control. It also includes special functions like tariff and fault counters, which are essential for commercial and diagnostic purposes. These specialized applications demonstrate the ERW 700’s flexibility and value across a wide spectrum of operational needs.
