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%.
