Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, has just released the NEW SERIES DFT DIFFERENTIAL FLOW TRANSMITTER. The Series DFT uses a segmented wedge differential producer to measure flow rates as related to pressure to monitor process fluids. The segmented wedge provides a simple and reliable restriction for sensing flow as related to pressure differential. The sensor can be mounted in any position and allows the designer to install it in any orientation: horizontal, vertical or inverted. The sensor is offered with three flow measuring ranges: 0.5-5, 1-10 and 1-15 GPM and three electrical output signals: 4-20 mA, 1-5 VDC and 1-10 VDC. The sensor offers low-cost precision with a measuring accuracy of ±2% of full-scale range and repeatability of ±0.5%.• Service: Compatible liquids. • Wetted Materials: End ports: PVC; Wedge element: PVC;Pressure sensor: polyethermide. • Flow Measuring Ranges: 0.5-5, 1-10, 1-15 GPM. • Accuracy: ±2% of full-scale. • Repeatability: ±0.5% of full-scale. • Response Time: Indication of no less than 90% of any step change within < 500 ms. • Power Requirements: 12-35 VDC. • Output Signal: 4-20 mA, 0-5 VDC or 0-10 VDC. • Maximum Current Consumption: 25 mA. • Minimum Load Resistance: 1000 ?. • Maximum Transmission Distance: 200 ft. • Resolution: Infinite. • Temperature Limits: 170°F (76°C). • Pressure Limits: 125 psig (8.6 bar). • Enclosure Rating: NEMA 4. • Maximum Particulate Size: 200 microns. • Weight: 1 lb (0.45 kg).
