6 Standards 06 Standards The test benches are suitable for meters complying with the European directives 75/33/EC and 79/830EEC and with standard ISO The test benches meet the requirements of ISO 4064, EN and OIML R 49 for initial verification tests, and OIML R 75 and EN 1434 for flow sensor initial verification tests. To achieve maximum accuracy the test benches are designed and constructed to comply with the international standard ISO The measurement process of the test bench is designed to achieve a combined measurement uncertainty of less than 0,2% (2 standard deviations) at typical volumes. The base measurement capability of the measuring assembly is better than 0.06%. Sensus Quality Assurance System is approved according to ISO Components of the measurement system such as, scales, flow meters, thermometers, pressure gauges, having influence on measured value were calibrated and are traceable to national standards using units of measurement in conformity with the International System of Units (SI). Scales have a resolution in conformity with EEC Directives 90/384 and 89/336. These types of test benches are being used in test laboratories accredited according to ISO All calculation in the testing program for determination of conventional true value, error calculation and corrections for density, buoyancy expansion, compressibility, temperature difference correction for balance flow meter and other calculations are programmed according to international standards. All stainless steel parts are of high quality ÀISI 304 (AISI 316L).

7 References Sensus Company is producing test benches for water, flow meters and heat meters for more than 20 years. Until now we have supplied more than 160 test benches in 222 countries around the World. Most of them are fully automated. Every important hydraulic component of the test bench is connected to the system with precise thread connections for easy dismanting during maintenance. Measuring principle of the scales is based on Electromagnetic Force Compensation (EFC). This EFC provides you with excellent reproducibility together with high resolution. The measuring cell can be tested with the integrated calibration weight - just by pressing a key. This calibration weight automatically considers the individual gravity at different places on earth. High precision - working immediately Electromagnetic master meters of class 0,15% used in test benches have ceramics liner. Certified according to ISO 9001 Quality Management System ÖQS Reg.no. 3496/0 Open type diverters have divertion times from 0, ,1s with possibility to detect up to 5 points of divertions period.
