NIT NO. 18 ITEM NO. 4

Supply of Velocity based flow meter model FL 432 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. Make: Seimens/EIP/VEGA 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: 12 VDC, Static 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 mm Water Level Radar Frequency: 26 GHz Water Level Radar Antenna Type: Planar microstrip array antenna Water Level Radar beam angle: 10° Flow Velocity measurement range: 0.05-21 m/s Flow Velocity accuracy: 8.8 mm/s Flow Velocity Resolution: 1 mm/s Flow Velocity Radar Transmission Frequency: 24 GHz Flow Velocity radar Beam Angle: 12° X 12° Water Surface distance: 0.5-35 m Operating temperature: - 35 to 60°C Storage temperature: -40 to 60°C Working Humidity ≤ 95% Application occasions: Static water or moving water Acquisition Interval: 5s to 24 Hours can be set Digital interface: RS 485MODBUS communication protocol Wiring Port: M 20* 1.5 X 2, Make : EIP/Siemens /VEGA
