1 / 2 page  F-1 F DIGITAL PLASTIC PADDLEWHEEL FLOWMETERS FP1400 Series U Polypropylene or PVDF Models U 29 Engineering Units (Including User Defined) U Two Programmable Totalizers U Programmable Alarms U Isolated Analog 0 to 5 Vdc or 4 to 20 mA U RS232 Communications Standard U Local Key Pad and 2 x 16 Characters LCD Display U Free Communication Software with Data Logging Capability FP1400 Series flowmeters support various functions including; two independently programmable flow totalizers, user programmable low, high or range flow and temperature alarm, two sets of user programmable optically isolated outputs, self diagnostic alarm, and flow pulse output. The flow rate can be displayed in 29 different volumetric or mass flow engineering units. Flowmeter parameters and functions can be programmed locally via optional key pad and LCD or remotely via the RS232/RS485 interface. Local 2 x 16 LCD readout with adjustable backlight provides flow rate, temperature, total volume reading in currently selected engineering units, diagnostic events indication and feature a password protected access to the process parameters to ensure against tampering or resetting. Liquid flowing through the unit causes the paddlewheel to spin. As the magnets embedded in the paddle spin past the sensor, electrical pulses are produced in which frequency is proportional to the flow rate. The number of pulses per desired time interval and the K-factor (number of pulses/gal) make it is possible to calculate the flow rate and volume passing through the unit. On board CPU and signal conditioner circuitry perform accurate flow and total computation, digital communication and analog 0 to 5 Vdc or 4 to 20 mA output signals. Non-volatile memory stores all hardware specific and user programmable variables, including flow linearization table. SPECIFICATIONS Viscosity: 1 cSt (water) can be used for liquids up to 50 cSt with field calibration (max flow range may be affected) Flow Accuracy (Including Linearity): ±1% of FS Repeatability: ±0.25% of FS Temperature Measurement Range: 60°C (140°F) Temperature Accuracy (Including Linearity): ±0.5°C Flow Response Time: Approx 1 sec (above 10% of full scale flow), approx 2 seconds (below 10% of full scale flow) Maximum Pressure: 10 bar (150 psig) Maximum Pressure Drop: @ 15 psi for sized units @ 20 psi all other sizes Ambient Temperature: -10 to 60°C (14 to 140°F) Output Signals: Linear 0 to 5 Vdc (3000 Ω minimum load impedance); linear 4 to 20 mA (500 Ω maximum loop resistance). Maximum noise 20 mV peak to peak (for 0 to 5 Vdc output) Flow Pulse Output: 3.3 Vdc amplitude (3000 Ω min load impedance) Optically Isolated Outputs: UCE 40 Vdc, ICE 150 mA Power: 11 to 26 Vdc, 100 mV maximum peak to peak output noise Consumption: +12 Vdc (150 mA maximum); +24 Vdc (100 mA maximum); circuit board have built-in polarity reversal protection, 300 mA resettable fuse provide power input protection Communications: RS232 standard, RS485 (optional) FP1408 shown larger than actual size. |
