When can a measurement section be used?
A measuring section is equipped with upstream and downstream pipe lengths in compliance with the criteria of the standard (roughness, circularity ...) to ensure good measurement accuracy.
The measurement section is the compromise, from equipment and accessories point of view, between:
- integrated orifice (special flanges, DN ≤ 40, pressure taps in the corners)
- the high-precision measuring tube (complete tube with corner or flange pressure taps, manifold, pressure transmitter, temperature sensor if applicable)
But the respect of the standard for all the criteria influencing the measurement accuracy (upstream and downstream tube lengths, roughness, circularity) is the same for these 3 devices.
