Misuratore di portata ad ultrasuoni FSV-L

volumetricoa gasoliocon montaggio a parete

Ultrasonic flow meter for fixed installation using the transit time difference measurement method. Leveraging the latest electronic advancements and digital signal processing technology, this device is compact and lightweight, offering increased accuracy and ease of use while maintaining excellent immunity to air bubble formation. Communication capability (MODBUS®: optional) is also available.Application Areas: HVAC systems (measurement of heating and cooling water flow), heating, ventilation, and air conditioning (HVAC) systems, energy-saving applications, etc.2 measurement channels and energy consumption calculation functionHigh measurement accuracy: ±1.0%Fast response time: 0.2 secondsIP67 protectionOutput signals: 4-20 mA outputs (2 points), pulses and alarms (4 points)Optional RS485 MODBUS™ communicationFluidHomogeneous liquids that allow the propagation of ultrasonic waves (service water, wastewater, industrial water, seawater, pure water, irrigation water, oil, etc.)Measurement typeUltrasonic measurement by transit time difference - 1 or 2 channelsSpecific functionsTwo independent measurement channels (FSVE_A12-L)One 2-channel measurement channel (FSVE_A12-L)One measurement channel and energy calculation (FSVE_B12-L)Fluid temperatureFrom -40°C to 200°C (depending on sensor)Pipe typeSensorOuter diameterMaterialFSSA (V-mount)25-225 mmPlastic (PVC, etc.)Metal (stainless steel, steel, copper, aluminum, etc.)FSSC (V-mount)50-600 mmFSSC (Z-group)600-1200 mmFSSD (V-mount)13-100 mmFSSE (V or Z-mount)200-6000 mmFSSH (V or Z-mount)50-400 mmRangeFrom 0 to ±0.3.....±32 m/sAccuracy±1% of velocity (flow velocity ≥2 m/s)Response time0.2 seconds (high-speed mode)Operating temperatureFrom -20°C to +55°C (converter)From -20°C to +60°C...80°C (depending on sensor)Analog output4-20 mA DC, 1 point (max load: 600Ω)Contact outputOpen collector: 4 pointsTotal, alarm, etc.Total pulse output: from 1 pulse/day to 100 pulses/sec (open collector)Serial communicationRS-485 (MODBUS) (optional)DisplayBacklit LCD, 2 lines of 16 digitsKeypad4 keys (ESC, up, shift, enter)Power supply voltage100-240 V AC, 50/60 HzConverter housingAluminum alloy, IP67Converter mountingWall or pipe mountingConverter dimensions (mm)H2240 x W247 x D134Reference: FSV-L-1Public price: 3615 €Technical specifications:Measurement method: Ultrasonic, transit time differenceNumber of channels: 2Accuracy: ±1.0%Response time: 0.2 sProtection: IP67Outputs: 4-20 mA (2 points), pulses and alarms (4 points)Optional communication: RS485 MODBUS™Power supply: 100-240 V AC, 50/60 HzMounting: Wall or pipeConverter housing: Aluminum alloyDisplay: Backlit LCD, 2 lines x 16 digitsKeypad: 4 keys (ESC, up, shift, enter)Fluid temperature: -40°C to 200°C (depending on sensor)Operating temperature: -20°C to +55°C (converter), -20°C to +60°C...80°C (sensor)Pipe compatibility: Plastic (PVC, etc.), Metal (stainless steel, steel, copper, aluminum, etc.)Pipe diameter range: 13 mm to 6000 mm (depending on sensor)Range: 0 to ±32 m/sAnalog output: 4-20 mA DC, 1 point (max 600Ω)Contact output: Open collector, 4 pointsSerial communication: RS-485 (MODBUS) (optional)Converter dimensions: H2240 x W247 x D134 mm
