DX-LLX-1C radar flowmeter Introduction: DX-LLX-1C radar flowmeter is a radar type flow measurement product that can simultaneously measure water level, velocity, flow and cumulative flow. It uses the Doppler radar velocity measurement principle to detect the surface velocity of water flow, and uses the built-in radar water level gauge to measure water depth. The velocity area method can be used to calculate the velocity of the section by measuring the water depth and velocity and the section shape set inside the equipment. Microwave radar is not affected by temperature gradient, pressure, air density, wind or other meteorological environmental conditions, so it is easy to maintain and use. The radar can set different transmission frequencies, which can effectively avoid the mutual interference of radar beams of adjacent products during multi-point close range detection. In addition, the monitoring system or unit can measure the water flow of natural river/urban river, canal/culvert/pipeline profile according to the velocity value (multi-point measurement) obtained by detection, together with the geometric shape information of river section, etc. The product is applied to the monitoring of water flow velocity in natural rivers, canals/culverts/pipelines characteristic: 1. Imported 24GHz radar speed detection module and 26GHz radar water level module are built-in. 2. CW planar microstrip radar non-contact detection is not affected by climate, sediment and floating objects. 3. Fast and accurate measurement, stable data output, and suitable for high velocity environment in flood season. 4. The antenna transmission frequency is flexible and adjustable, which can effectively avoid mutual interference of multiple products. 5. Multiple data communication interfaces can be set to facilitate user system connection. 6. The measurement operation mode is combined with the sleep mode to save energy and reduce consumption. 7. It is designed to prevent internal condensation, water and lightning, and is applicable to various outdoor environments. 8. Compact appearance, easy installation and maintenance. 9. Built in anti rain interference algorithm, which is not affected by rainfall. Technical parameters: Effective distance: 0-40m Flow rate range: 0.10-20m/s; 0.10-40m/s Measurement accuracy: ± 0.01m/s; ± 1% of measured flow rate Resolution: 0.001m/s Water level range: 0-30m or 0-70m Water level accuracy: ± 3mm Resolution: 1mm Power supply range: 9-26VDC Power supply current:<50mA (12V) Standby current:<1mA Communication interface: RS485 (Modbus), 4-20mA Operating temperature: - 20-60 ℃ Storage temperature: - 20-70 ℃ Relative humidity: 0-95% RH Protection grade: IP67
