The UF 322 range uses transit-time ultrasonic principle to m e a s u re velocity. The UF 322 co-s and UF 322 co m e a s u re the flowrate by integrating the hydraulic profile fro m 2 to 6 velocity chords : PERFORMANCE m Accuracy on velocity measurement < +/- 0.5 % m Accuracy on level acquisition < 0.1 % (excluding errors of level device) m Accuracy of section description < 0.25 % m Typical accuracy of flow calculation : 1 to 5 % according to application and number of chords m Maximum length of channel : according to the f requency of probes (0.5 MHz and more ) m Calculation of flowrate by programmable rule : Flow = f (Level) when all probes are out of flow FEATURES m Graphical display of readings and curv e s m Easy to use keypad steps through set up windows m Diagnostic screen shows : Echo display, gain … m Language choice : English, French, German, Spanish, Italian… m 8 site set-ups can be stored in memory m Software for PC / Windows NT, 95, 98 m Date, time data logger . 8 064 lines of 4 variables (32 400 in option) or . 4 032 lines of 9 variables (16 200 in option) m Direct transfer of data to spreadsheet m Display : flow, velocity, level, volume … m Isolated programmable current output 4-20 mA m 3 programmable relays outputs : alarms, faults totalisation… m Numerical output RS 232 or 485 - JBus/Modbus m Odd shaped channels can configured in set-up (in 20 trapezial sections) m Hydraulic model describes in 20 sections : - fixed model : absolute mode - variable model : relative mode m Possible acquisition of 2 levels - alarm if different m Ultrasonic signal processing with DSP (Digital Signal Processing) ELECTRICAL CHARACTERISTICS m Power supply (max. consumption : 10 W) : . 230/115 V AC 50/60 Hz . 12 - 32 V DC as standard (option : 50 V) m Inputs : 2 signals 4-20 mA for level(s) 15 V power supply for piezzo or ultrasonic sensors 2 wires m Outputs - 1 output 4-20 mA isolated – resolution 10-4 - 3 static relays outputs 100 V - 100 mA - 10 VA - 1 output RS 232 or 485, 300 to 9600 Bauds, JBus/ModBus. MECHANICAL CHARACTERISTICS m UF 322 e n c l o s u re is cast aluminium - epoxy coated ; all cable entries are via plug type connections m Protection IP 67 ; Relative humidity : 90 % Temperature : - 25° C / + 50° C m Dimensions : version CO-S : 340 x 240 x 123 mm (H x L x D) version CO : 340 x 240 x 225 mm m Submergeable probes. NOTES ON SITE SELECTION m P e rf o rmance and results mainly depend on geometric readings, positioning and number of probes. m Use of Ultraflux probe mounting tools is recommended m Avoid sites with bubbles or entrained air Velocity 3 (V3) Velocity 2 (V2) Velocity 1 (V1) Level Flow Example of results (3 chords) t Supply Outputs RS UF322 co Level 2 (and/or) Level 1 Junction cable Probes
