DIFFERENTIAL FLOW TRANSMITTER.

Description

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%.
