HY.FLOW600 handheld Doppler flow meter I. Introduction handheld Doppler flow meter / flow meter, using the Doppler principle to measure the non-full pipe (pipe, tube or other egg-shaped tube) flow, provides instantaneous flow value and cumulative flow value, meter built-256M data storage space, external memory card sensor 4GSD long-term work and live in poor effluent quality, optional SMS or GPRS wireless module for remote telemetry. Second, the technical parameters: flow range of 0.02m / s ~ 10m / s velocity measurement resolution of 1mm / s velocity depth measurement accuracy of ± 2% range 0 ~ 5m depth of 2mm depth resolution Accuracy ± 0.2% 0 ~ 65oC temperature range of built-in power meter Battery-powered display LCD touch screen display recording period manual and automatic storage capacity 4G memory instantaneous velocity, water level, water temperature measuring point name of the stored measurement range of natural rivers, streams, pipes, trapezoidal channels, rectangular drainage flow rate, the cross section measurement Third, the application range of applications broader scope, such as: widely used in storm monitoring, wastewater treatment, natural rivers, municipal water supply and drainage, water loss / infiltration monitoring, irrigation flow monitoring, industrial pollution measurement, research & tidal estuaries, fisheries / water conservation, coastal erosion research, sewer / culvert process monitoring, monitoring road drainage canals flow studies, river flow monitoring and other industries. Main menu of non-pipeline, siltation trapezoidal canal drainage pipes irregular rectangle measuring storage record four channels, the data is stored within the main menu after each measurement data is automatically stored or manually good storage, you can touch the screen to view, or SD card to store your computer to view, you can do statistics Reports graphics, 4GSD card storage velocity, flow rate and other data.
