In contrast to total emissions calculations, flow is an equally important factor as pollutant concentration. The accuracy of flow measurement plays a crucial role, therefore,HJ353-2019, HJ354-2019, HJ355-2019, HJ356-2019 industry standards specify clear requirements for flow error and its measurement. DeRunThe DR-102A Open Channel Flow Comparison Measurement System consists of an on-site flow measurement and transmission unit, an online flow meter data acquisition unit, and an open channel flow meter comparison data management system. It employs high-precision level sensors, still water well level measurement, video recognition for on-site flow data acquisition, and real-time level comparison without delay. This system provides a one-stop solution for on-site flow comparison, generates reports on-site, and meets the technical requirements of national environmental protection standards such as HJ353-2010, HJ354-2019, and HJ355-2019 for measurement accuracy and testing methods. It is an ideal tool for environmental monitoring, environmental supervision, third-party operation companies, and third-party testing companies to calibrate, compare, and verify the validity of data for installed open channel flow meters. Feature Highlights: Suitable for various weirs: Compatible with Barcher weirs, rectangular weirs, right-angled triangular weirs, and equal-width thin-walled weirs, etc.; Operation Simple: Built-in multiple weir channel standard formulas for easy setup; Accurate Measurement: High precision measurement, unaffected by smog, foam, condensation, and other factors.; Video Recognition: Professional video recognition technology, effortlessly and accurately capture online traffic data; Real-time Comparison: No time delay in real-time comparison between the on-site flow meter level and the comparison device level; Report Output: Synchronously obtain standard traffic and online traffic, automatically perform error calculation, and output reports on-site.; Data Export: All reports can be exportedUSB export for easy editing and application. Battery-powered: Continuously operational with battery power12 hours. Technical Specifications: Flow Measurement Range Determined by weir type and water level Flow measurement error ≤3% Repetitive Flow Error ≤1% Level Measurement Range 50.00mm~1000.00mm Level measurement error ≤0.70mm Level resolution ≤0.05mm Level repeatability error ≤0.15mm Timekeeping Error ≤10s/24h Continuous Operating Time 12h Power supply method DC12V (rechargeable battery) / AC220V Work Environment Temperature （0~50）℃ Workplace humidity ≤85%RH
