The water meter calibration test benches comply with OIML R 76 requirements and support in-process weight loading for real-time calibration during operation.
For water meter verification, the Q3 test bench employs a proprietary dynamic imaging system that integrates high-speed photography (≥120 fps) with trailing pointer tracking technology. Q2 and Q1 meters utilize a hybrid optical-inductive sensing method for precision signal acquisition. The system operates with fully automated focusing and supports parallel testing of up to 10 units.
Specialized meters requiring manual intervention can be processed via software-controlled start-stop commands, with automated error calculations performed without disrupting standard workflows. Water Meter Calibration Test Benches dynamic image processor simultaneously captures both mechanical and sensitive pointers, reducing water consumption at low-flow thresholds (≤0.001 m³/h) and enhancing verification efficiency by 40% compared to conventional methods.
All sampled images are archived as raw image files (TIFF/PNG formats) on the central computer, ensuring full traceability for audit purposes.
