with pressure-measuring point for air flow measurement
Air flow measurement:
The differential pressure approach compares the static pressure before the
inlet nozzle with the static pressure inside the inlet nozzle.
Air flow can be calculated on the basis of the differential pressure (difference
in pressure of the static pressures) in keeping with the following equation:
If constant air flow control is used, then the nozzle pressure has to be kept
constant:
k takes into account the specific nozzle characteristics.
1 or 4 pressure measuring points are spaced along the circumference of
the inlet nozzle. Connection on the customer side is accomplished via a
premounted T tube connector. This tube connector is suited for pneumatic
hoses with an internal diameter of 4 mm.
