Full CRS - Full Computer Registration Software

The full version of our Metrus Free CRS comes with database integration and access to up to 8 sensors. It can be customized to meet your specific needs and offers a wide range of features and tools.

Leakage calculation and testing are performed according to EN60534-4 and EN12266 with high measurement accuracy using the proprietary METRUS analog-digital converter (PC box). Separate testing of the housing, seat leakage, and set pressure for safety valves is possible. During safety valve testing, individual distinctions can be made between leakage point, pop pressure, opening pressure, and closing pressure.

Measurement data recording and graphical representation are carried out on an industrial panel PC with a touchscreen. Test reports can be customized with your company logo and address and are freely configurable. Additionally, it is possible to directly export test reports as PDF files to a predefined network path. The evaluation is performed automatically and indicates whether the test has passed or failed. Optionally, integration with a higher-level ERP system is also possible.

What is METRUS CRS?

CRS stands for Computer Registration System. In the world of test benches, it refers to a system that transfers test results from measuring devices to a computer. Instead of manually recording measurements on paper, METRUS CRS tracks the measurements and displays them in graphs. Instead of using form inputs, METRUS CRS stores the results digitally, allowing users to either print them or save them in PDF format.

It is not a PLC (Programmable Logic Controller) but merely a system for recording measurement values. This means that METRUS CRS does not control the test bench actions but records and displays the results.

A CRS typically consists of the following components:

• Software running on a computer
• Sensors monitoring the test bench parameters (e.g., pressure, flow, stroke, temperature)
• Electronics to connect the sensors to the computer

METRUS uses proprietary electronics, referred to as the "PC-Box," to convert analog sensor signals into digital data that can be processed by the software. METRUS CRS is usually delivered alongside METRUS test benches, but it can also be integrated into existing METRUS test benches.

METRUS CRS is a database solution that stores all relevant data, such as test data, object data (data of the objects being tested), customer data, and sensor data. It can work with either a MySQL database or a Microsoft SQL database, depending on customer requirements. A migration from one database platform to another is possible at any time.

Flexibility of METRUS CRS Software

The METRUS CRS Software is a highly flexible platform that can be tailored to specific needs. It offers a wide range of features and tools, including measuring devices, graphs, and database management. With its scripting technology, customized applications can be developed, such as:

• Safety valve testing (METRUS CRS SV)
• Control valve testing (METRUS CRS CSV)

The core of these specific applications is the same. The system allows for the expansion and optimization of existing test benches to meet the specific requirements of a company or industry.

The specific applications for safety valve testing (SV) and control valve testing (CSV) provide everything needed for complete and standards-compliant testing. They include implementations of key testing standards such as API 527, EN 12266, or other recognized standards. If a less common standard is required, it can be integrated through custom adaptation.

METRUS CRS thus offers complete flexibility to optimize your testing processes and ensure that all requirements and standards are reliably met.
