N2021-11 Small Ultrasonic Doppler Velocimeter Introduction: Small size, easy to install, suitable for low water level sites; There are two types to choose from: no pressure and pressure. When carrying pressure, ultrasonic ranging can also be carried; Positive and negative flow velocity measurement (no negative flow velocity function when water level is below 0.4m), made of POM material, pressure resistant and wear-resistant. Technical parameters: Power supply: 10VDC~30VDC Flow velocity measurement range (water level should be 5m above the top of the sensor): The positive flow velocity is+0.03m/s to+5.00m/s The negative flow velocity is -1.00m/s to -0.3m/s (customizable flow velocity range) Depth measurement range: 0.02-3.00m, 0.02-10.00m Flow velocity measurement accuracy: ± 2-3% of the measured flow velocity Depth measurement accuracy: ± 5% Flow velocity measurement resolution: 1mm/s Depth measurement resolution: 1mm Protection level: IP68 Wire length: 20m (other wire lengths need to be customized) Product selection: Product type: DP Doppler Product series: GS: Universal Series Depth range: P0： No pressure; P30：3m ； P100：10m Shell appearance: F1： Small in size; F2： rotundity Shell material: P：POM； U：PPSU； C：POM+PC+ABS Communication method: C8：RS485 Elevation angle: D0： 0 ° elevation angle; D34： 34 ° elevation angle
