ABSTRACT:
A system for measuring the quantity of particulate material carried by a fluid flow. The system is connected to receive the fluid flow and induces a change in direction in that flow. The pressure drop of the fluid flow across the direction change is sensed and the pressure drop related to the quantity of particulate material within the fluid flow. In a preferred embodiment, the direction change is along a generally helical path with the pressure drop being measured across at least a portion of that path. The pressure sensors may be adjusted to measure static as well as positive and negative velocity pressures so as to zero out the pressure drop due to the fluid flow alone.
