• Portable radio wave (radar) current meter velocity detecting SURFACE VELOCITY RADAR / Water Flow Velocity 0.2~18m/s 24GHz (Including tripod） Product introduction: simple, fast, accurate, reliable and stable channel and river measuring devices have always been the pursuit of flow measurement ZJ * * * * in various countries. Due to the limitations of science and technology, this problem has not been solved. We use the radar velocity sensor, adopt the single point velocity method combined with hydrofluidics, deduce the average velocity of the river through the single point velocity, and calculate the water flow in combination with the water level and flow section area. Installation conditions 1. Installation of flow rate sensor The velocity sensor shall be installed above the center of the water surface and shall be as horizontal as possible. The transmitting surface of the sensor shall form an included angle of 30 ° - 45 ° with the water surface. There shall be no branch near the installation point of the river channel, and the flow field shall be relatively stable (in case of uncertainty, portable measurement of on-site velocity distribution can be used first), so as to determine the fixed position and method of the sensor. At present, the commonly used sensor fixing methods include fixed support type (fixed on the bank) and measuring bridge suspension type. For portable, special test points can be set in advance on conditional rivers and channels to facilitate measurement. 2. Installation of water level gauge Pressure water level gauge, float water level gauge and ultrasonic water level gauge can be used. For specific installation, please refer to the instructions provided by relevant products to guide the installation. 3. Host installation Before model selection, it is required to determine the on-site power supply, and inform the manufacturer in advance. AC220V (power 20W), DC12V (power 5W) and solar power supply are optional (100W solar panels need to be selected for long-term cloudy and rainy weather). Corresponding instrument boxes can be equipped for field installation. (there are engineering plastic explosion-proof and waterproof type, stainless steel shell type and steel plate plastic spraying shell type) The instrument can be equipped with GSM, GPRS and CDMA communication; Before determining the scheme, check whether the on-site communication signal meets the requirements? For other uncertain factors, please contact the manufacturer. seven technical parameter General: Operating temperature range: - 30~+70℃ Relative humidity range: 20%~80% Storage temperature range: - 30 ℃ to 70 ℃ Instrument details Measuring range: 0.2~18m/s Measurement accuracy: ±2%±0.03m/s Radio wave emission angle: 12° Standard power of radio wave transmission: 10mW Radio frequency: 24GHz Angle compensation: Vertical angle automatic Storage size: 100 measurements Battery Battery type Rechargeable lithium ion battery Battery capacity (2800mah) Standby mode (at 25 ℃) More than 6 months Continuous work More than 10 hours
