Ultrasonic flow measurementApplication fieldsAir conditioning systems (measurement of heating and cooling water flow), HVAC installations, energy-saving applications, etc.Benefits2 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), pulse and alarm (4 points)Optional MODBUS™ RS485 communicationThis fixed-mount ultrasonic flowmeter applies a measurement method based on transit time difference. Leveraging the latest electronic advances and digital signal processing technology, we have developed a compact and lightweight device with greater accuracy and ease of use, while maintaining excellent immunity to air bubble formation. It also features communication capability (MODBUS®: optional).FluidHomogeneous 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 and energy calculation channel (FSVE_B12-L)Fluid temperature-40°C to 200℃ (depending on sensor)Pipe typeSensorOuter diameterHardwareFSSA (V-mount)25-225 mmPlastic (PVC, etc.)Metal (stainless steel, steel, copper, aluminum, etc.)FSSC (V-mount)50-600 mmFSSC (Z-mount)600-1200 mmFSSD (V-mount)13-100 mmFSSE (V or Z-mount)200-6000 mmFSSH (V or Z-mount)50-400 mmRange0 to ±0.3.....±32 m/sAccuracy±1% of velocity (flow velocity ≥2 m/s)Response time0.2 seconds (high-speed mode)Operating temperature-20°C to +55°C (converter)-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: 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 size (mm)Height 2240 x Width 247 x Depth 134Reference: FSV-L-1Public price: 3615 €Technical specifications:2 measurement channels and energy calculationHigh accuracy: ±1.0%Fast response: 0.2 sIP67 protection4-20 mA outputs (2 points), pulse and alarm (4 points)Optional MODBUS™ RS485Fluid temperature: -40°C to 200°C (sensor dependent)Pipe diameter: 13 to 6000 mm (depending on sensor)Power supply: 100-240 V AC, 50/60 HzConverter housing: Aluminum alloy, IP67Mounting: Wall or pipe
