The Series DFT from Dwyer Instruments Inc., Michigan City, IN, uses a segmented wedge differential producer to measure flow rates as related to pressure differential for process fluids. Available flow measuring ranges are 0.5–5 gpm, 1–10 gpm, or 1–15 gpm with 4–20 mA, 1–5 VDC, or 1–10 VDC outputs. Measuring accuracy is ±2% F.S. and repeatability is ±0.5%. The sensor can be mounted in any position.
