Item Description
1
Supply, Installation, Testing and Commissioning of Radar Type Velocity based flow meter with measurement of flow with product of velocity and level on continuous basis. To be mounted on open channel the system should simultaneously read both velocity and level to calculate flow / discharge. The system Characteristics 1. Non-Contact Measurement, low power consumption, small beam angle 2. Standard RS 485 Modbus Communication 3. Convenient Installation 4. Flow Velocity and Water Level Output in one. Supply Voltage: 24 VDC or lesserStatic Current ≤ 1 mA (@ 12 V), Operating Current≤ 100 mA (@ 12 V), Water Level Range: 15m (range optional 30 m / 45 m), Water Level Accuracy ± 3 mm, Water Level Resolution: 1 mmWater Level Radar Frequency: 26 GHzWater Level Radar Antenna Type: Planar microstrip array antennaWater Level Radar beam angle: 10 °Flow Velocity measurement range: 0.05 – 21 m/sFlow Velocity accuracy: 8.8 mm /sFlow Velocity Resolution: 1 mm /sFlow Velocity Radar Transmission Frequency: 24 GHzFlow Velocity radar Beam Angle: 12 ° X 12 °Water Surface distance: 0.5 – 35 mOperating temperature: - 35 to 60 ° CStorage temperature: - 40 to 60 ° CWorking Humidity ≤ 95 %Application occasions: Static water or moving water Acquisition Interval: 5s to 24 Hours can be setDigital interface: RS 485MODBUS communication protocolWiring Port: M 20 * 1.5 X 2, Configuration should be through Android/ iOS Mobile Bluetooth Application downloadable from App Store only.
