UFT-1A-3

FLOW UNIVERSAL FLOW TRANSMITTER MODEL UFT-1 DESCRIPTION The M odel UFT-1 Universal Flow Transmitter is a solid-state, digital signal converter designed to operate with Data Industrial 200 Series flow sensors. Both analog (4-20 mA) and pulse outputs are available. The Model UFT-1 may be mounted in an optional NEMA 4X enclosure or with digital display of gpm or totalized flow (in a non-watertight enclosure). FEATURES • • • • • • Analog and pulse outputs Optional watertight (NEMA 4X) enclosure Optional displays for flow rate and totalization Low cost Excitation voltage for flow sensors LED indication of pulse activity UFT-1 UFT-1E-1 APPLICATION Analog Output (rate) The Model UFT-1 analog transmitter converts a Data Industrial digital flow signal into a precalibrated 4-20 mA signal. It must be calibrated for each Data Industrial flow sensor installation. The pipe type, size, and maximum flow rate must be specified at the time of order if 4-20 mA output is to be used. Pulse Output (totalization) The M odel UFT-1 p ulse output divides the Data Industrial digital flow signal by a jumper-selectable 10 or 100 position to provide a more usable digital pulse. The pulse output is normally used where flow totalization is required. A simple conversion formula, using the flow factors for Data Industrial flow sensors on the next page, can convert the digital pulses to totalized gallons. The pulse output is an optoisolated transistor switch that can be wired to source or sink pulses to totalizer equipment. Note: This unit is not intended for field setup or field calibration. 3.25 (8.25) in (cm) Pulse Out + Pulse Out – mA Signal Out XDCR Signal In 24 VDC Power Common 2.19 (5.56) SPECIFICATIONS Supply voltage Operating temp Operating humidity Output Input 24 VDC @ 60 mA 32° to 140°F (0° to 60°C) 5% to 95% noncondensing 4-20 mA and solid-state switch 15-150 Hz full scale (dry or electronic contact) Max loop resistance Output switch rating Accuracy Step response 4-20 mA output 750Ω @ 24 VDC 40 VDC @ 200 mA ±0.5% 5 sec from 10% to 90% 2004 KELE CATALOG • www.kele.com • USA 888-397-5353 • International 901-382-6084 223 FLOW DIMENSIONS FLOW UNIVERSAL FLOW TRANSMITTER MODEL UFT-1 WIRING Output Pulse Divider Selection Jumper Pulse (10 or 100) 100 Out 10 Pulse Out + Pulse Out – mA Signal Out XDCR Signal In 24 VDC Power XDCR Sig In PWR Common Totalize + – Power Typical Totalizer Hookup (red) + Flow Sensor (black) – + 4-20 mA – Output Transducer Power Option Jumper (Leave on for Data Industrial flow sensors.

The optional watertight enclosure provides a watertight seal against contaminants. While field calibration is not required with the UFT-1, flow conversion must be accomplished at the monitoring computer. The information below is provided for making the conversion calculations. TABLE 1. FLOW FACTORS FOR DATA INDUSTRIAL FLOW SENSORS MODEL PIPE SIZE in (cm) FLOW FACTOR GALLONS/PULSE JUMPER IN JUMPER IN 10 POSITION 100 POSITION FLOW RATE Flow (gpm) = (mA measured - 4 mA) x Maximum gpm 16 Maximum gpm is the flow rate at 20 mA output on the transmitter and must be specified at the time the UFT-1 is ordered for proper calibration. TOTALIZED FLOW Totalized Gallons = (Flow Factor) x (Output Divider) x (Total Pulses) For totalized m3, multiply the above by 0.00379. Output Divider = 10 or 100 depending on jumper-selection. Flow factors per pulse are shown in the table at the right. 228PV-1.5 228PV-2 228B-2 228C-2 250B-0.5 250B-0.75 250B-1 250B-1.25 250B-1.5 220B-2.5 220B 220B 220B 220B 220B 220B 220B 220B 220B 220B 1-1/2 (3.81) 2 (5.08) 2 (5.08) 2 (5.08) 1/2 (1.27) 3/4 (1.91) 1 (2.54) 1-1/4 (3.18) 1-1/2 (3.81) 2-1/2 (6.35) 3 (7.62) 4 (10.16) 5 (12.7) 6 (15.24) 8 (20.32) 10 (25.40) 12 (30.48) 14 (35.56) 16 (40.64) 18 (45.72) 0.03118 0.04611 0.04579 0.04731 0.005646 0.007514 0.007015 0.01280 0.01780 0.03800 0.07280 0.1396 0.2457 0.3611 0.6710 1.080 1.630 1.944 2.502 3.158 0.3118 0.4611 0.4579 0.4731 0.05646 0.07514 0.07015 0.1280 0.1780 0.3800 0.7280 1.396 2.457 3.611 6.710 10.80 16.30 19.44 25.02 31.58 3.118 4.611 4.579 4.731 0.5646 0.7514 0.7015 1.280 1.780 3.800 7.280 13.96 24.57 36.11 67.10 108.0 163.0 194.4 250.2 315.8 FLOW Notes 1.
