HORIBA PTFM-ONE-DT Dual Pitot Tube Exhaust Flow Meter

Tube Diameter & Measuring Range

The System comes with a B & C Tube in parallel with each other and a valve in between.

• B-type: f42.7 / f39.7 mm (0.15 m³/min to 4.5 m³/min)

• C-type: f60.5 / f56.5 mm (0.3 m³/min to 10 m³/min)

Both B and C Tubes work in parallel with each other, providing a Max Flow of 14.5 m³/min.

Linearity

Either of the following:

• Within ±2.0 % of full scale

• Intercept: |a0| ≤ 1.0 % of full scale
  Slope: 0.98 ≤ a1 ≤ 1.02
  Standard estimated error: SEE ≤ 2.0% of full scale
  Coefficient of determination: r2 ≥ 0.990

Flow Rate Accuracy

Within ±1 % of full scale or within ±1.5 % of readings (whichever larger) (at flow rate of 20 % of full scale)
