N2018-01 Ultrasonic Doppler Velocimeter Introduction: The principle of ultrasonic Doppler flowmeter is to place an ultrasonic sensor in the measured channel or river, and the sensor emits ultrasonic waves into the water. Based on the reflected ultrasonic signal intensity and other parameters, the water flow velocity can be calculated. These data are transmitted to the user through built-in hardware and software. A device widely used for measuring the flow velocity of water in pipelines, channels, or rivers. This ultrasonic Doppler flowmeter is mainly used in fields where the water level is above 0.4 meters. For the field environment, there are two options: pressure and no pressure; POM material, wear-resistant and corrosion-resistant. Technical parameters: Power supply: 10.8VDC~26.4VDC Flow velocity range: ± 0.03m/s to ± 5m/s (customizable ± 0.03m/s to ± 10m/s) Water depth range: 0.02-3m, 0.02-10m (please confirm the maximum water depth before ordering) Flow velocity accuracy: ± 1% (accuracy for inspection and testing by the Ministry of Water Resources) Flow velocity accuracy: ± 1-3% (measurement accuracy may vary due to the influence of the on-site working environment) Depth accuracy: ± 3cm Flow velocity resolution: 1mm/s Temperature resolution: 0.1 ℃ Depth resolution: 1mm. IP68 protection level texture of material: POM Environmental temperature: 0 ℃~60 ℃ (non freezing state)
