Speed Sensors

The multi-hole velocity probe is one of the differential flow meters, which in principle is based on the Pitot tube. The mean value of the total fluid pressure is read through the holes on the inlet side of the probe and the pressure in the wake behind the probe is read on the holes on the outlet side. From the difference of these pressures, the mean flow rate and flow can be determined. The advantage of the speed probe is the low permanent pressure drop, simplicity of construction and the possibility of using the probe in circular and rectangular pipelines.
